• PetaPoco with parameterised stored procedure and Asp.Net MVC

  - by Jalpesh P. Vadgama

  I have been playing with Micro ORMs as this is very interesting things that are happening in developer communities and I already liked the concept of it. It’s tiny easy to use and can do performance tweaks. PetaPoco is also one of them I have written few blog post about this. In this blog post I have explained How we can use the PetaPoco with stored procedure which are having parameters.  I am going to use same Customer table which I have used in my previous posts. For those who have not read my previous post following is the link for that. Get started with ASP.NET MVC and PetaPoco PetaPoco with stored procedures Now our customer table is ready. So let’s Create a simple process which will fetch a single customer via CustomerId. Following is a code for that. CREATE PROCEDURE mysp_GetCustomer @CustomerId as INT AS SELECT * FROM [dbo].Customer where CustomerId=@CustomerId Now  we are ready with our stored procedures. Now lets create code in CustomerDB class to retrieve single customer like following. using System.Collections.Generic; namespace CodeSimplified.Models { public class CustomerDB { public IEnumerable<Customer> GetCustomers() { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; return databaseContext.Query<Customer>("exec mysp_GetCustomers"); } public Customer GetCustomer(int customerId) { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; var customer= databaseContext.SingleOrDefault<Customer>("exec mysp_GetCustomer @customerId",new {customerId}); return customer; } } } Here in above code you can see that I have created a new method call GetCustomer which is having customerId as parameter and then I have written to code to use stored procedure which we have created to fetch customer Information. Here I have set EnableAutoSelect=false because I don’t want to create Select statement automatically I want to use my stored procedure for that. Now Our Customer DB class is ready and now lets create a ActionResult Detail in our controller like following using System.Web.Mvc; namespace CodeSimplified.Controllers { public class HomeController : Controller { public ActionResult Index() { ViewBag.Message = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return View(); } public ActionResult Customer() { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomers()); } public ActionResult Details(int id) { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomer(id)); } } } Now Let’s create view based on that ActionResult Details method like following. Now everything is ready let’s test it in browser. So lets first goto customer list like following. Now I am clicking on details for first customer and Let’s see how we can use the stored procedure with parameter to fetch the customer details and below is the output. So that’s it. It’s very easy. Hope you liked it. Stay tuned for more..Happy Programming

• Visual Studio 2010 Beta 2 Startup Failures

  - by Rick Strahl

  I’ve been working with VS 2010 Beta 2 for a while now and while it works Ok most of the time it seems the environment is very, very fragile when it comes to crashes and installed packages. Specifically I’ve been working just fine for days, then when VS 2010 crashes it will not re-start. Instead I get the good old Application cannot start dialog: Other failures I’ve seen bring forth other just as useful dialogs with information overload like Operation cannot be performed which for me specifically happens when trying to compile any project. After a bit of digging around and a post to Microsoft Connect the solution boils down to resetting the VS.NET environment. The Application Cannot Start issue stems from a package load failure of some sort, so the work around for this is typically: c:\program files\Visual Studio 2010\Common7\IDE\devenv.exe /ResetSkipPkgs In most cases that should do the trick. If it doesn’t and the error doesn’t go away the more drastic: c:\program files\Visual Studio 2010\Common7\IDE\devenv.exe /ResetSettings is required which resets all settings in VS to its installation defaults. Between these two I’ve always been able to get VS to startup and run properly. BTW it’s handy to keep a list of command line options for Visual Studio around: http://msdn.microsoft.com/en-us/library/xee0c8y7%28VS.100%29.aspx Note that the /? option in VS 2010 doesn’t display all the options available but rather displays the ‘demo version’ message instead, so the above should be helpful. Also note that unless you install Visual C++ the Visual Studio Command Prompt icon is not automatically installed so you may have to navigate manually to the appropriate folder above. Cannot Build Failures If you get the Cannot compile error dialog, there is another thing that have worked for me: Change your project build target from Debug to Release (or whatever – just change it) and compile again. If that doesn’t work doing the reset steps above will do it for me. It appears this failure comes from some sort of interference of other versions of Visual Studio installed on the system and running another version first. Resetting the build target explicitly seems to reset the build providers to a normalized state so that things work in many cases. But not all. Worst case – resetting settings will do it. The bottom line for working in VS 2010 has been – don’t get too attached to your custom settings as they will get blown away quite a bit. I’ve probably been through 20 or more of these VS resets although I’ve been working with it quite a bit on an internal project. It’s kind of frustrating to see this kind of high level instability in a Beta 2 product which is supposedly the last public beta they will put out. On the other hand this beta has been otherwise rather stable and performance is roughly equivalent to VS 2008. Although I mention the crash above – crashes I’ve seen have been relatively rare and no more frequent than in VS 2008 it seems. Given the drastic UI changes in VS 2010 (using WPF for the shell and editor) I’m actually impressed that the product is as stable as it is at this point. Also I was seriously worried about text quality going to a WPF model, but thankfully WPF 4.0 addresses the blurry text issue with native font rendering to render text on non-cleartype enabled systems crisply. Anyway I hope that these notes are helpful to some of you playing around with the beta and running into problems. Hopefully you won’t need them :-}© Rick Strahl, West Wind Technologies, 2005-2010

• Inequality joins, Asynchronous transformations and Lookups : SSIS

  - by jamiet

  It is pretty much accepted by SQL Server Integration Services (SSIS) developers that synchronous transformations are generally quicker than asynchronous transformations (for a description of synchronous and asynchronous transformations go read Asynchronous and synchronous data flow components). Notice I said “generally” and not “always”; there are circumstances where using asynchronous transformations can be beneficial and in this blog post I’ll demonstrate such a scenario, one that is pretty common when building data warehouses. Imagine I have a [Customer] dimension table that manages information about all of my customers as a slowly-changing dimension. If that is a type 2 slowly changing dimension then you will likely have multiple rows per customer in that table. Furthermore you might also have datetime fields that indicate the effective time period of each member record. Here is such a table that contains data for four dimension members {Terry, Max, Henry, Horace}: Notice that we have multiple records per customer and that the [SCDStartDate] of a record is equivalent to the [SCDEndDate] of the record that preceded it (if there was one). (Note that I am on record as saying I am not a fan of this technique of storing an [SCDEndDate] but for the purposes of clarity I have included it here.) Anyway, the idea here is that we will have some incoming data containing [CustomerName] & [EffectiveDate] and we need to use those values to lookup [Customer].[CustomerId]. The logic will be: Lookup a [CustomerId] WHERE [CustomerName]=[CustomerName] AND [SCDStartDate] <= [EffectiveDate] AND [EffectiveDate] <= [SCDEndDate] The conventional approach to this would be to use a full cached lookup but that isn’t an option here because we are using inequality conditions. The obvious next step then is to use a non-cached lookup which enables us to change the SQL statement to use inequality operators: Let’s take a look at the dataflow: Notice these are all synchronous components. This approach works just fine however it does have the limitation that it has to issue a SQL statement against your lookup set for every row thus we can expect the execution time of our dataflow to increase linearly in line with the number of rows in our dataflow; that’s not good. OK, that’s the obvious method. Let’s now look at a different way of achieving this using an asynchronous Merge Join transform coupled with a Conditional Split. I’ve shown it post-execution so that I can include the row counts which help to illustrate what is going on here: Notice that there are more rows output from our Merge Join component than on the input. That is because we are joining on [CustomerName] and, as we know, we have multiple records per [CustomerName] in our lookup set. Notice also that there are two asynchronous components in here (the Sort and the Merge Join). I have embedded a video below that compares the execution times for each of these two methods. The video is just over 8minutes long. View on Vimeo  For those that can’t be bothered watching the video I’ll tell you the results here. The dataflow that used the Lookup transform took 36 seconds whereas the dataflow that used the Merge Join took less than two seconds. An illustration in case it is needed: Pretty conclusive proof that in some scenarios it may be quicker to use an asynchronous component than a synchronous one. Your mileage may of course vary. The scenario outlined here is analogous to performance tuning procedural SQL that uses cursors. It is common to eliminate cursors by converting them to set-based operations and that is effectively what we have done here. Our non-cached lookup is performing a discrete operation for every single row of data, exactly like a cursor does. By eliminating this cursor-in-disguise we have dramatically sped up our dataflow. I hope all of that proves useful. You can download the package that I demonstrated in the video from my SkyDrive at http://cid-550f681dad532637.skydrive.live.com/self.aspx/Public/BlogShare/20100514/20100514%20Lookups%20and%20Merge%20Joins.zip Comments are welcome as always. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• SQL SERVER – A Picture is Worth a Thousand Words – A Collection of Inspiring and Funny Posts by Vinod Kumar

  - by pinaldave

  One of the most popular quotes is: A picture is worth a thousand words. Working on this concept I started a series over my blog called the “Picture Post”. Rather than rambling over tons of material over text, we are trying to give you a capsule mode of the blog in a quick glance. Some of the picture posts already available over my blog are: Correlation of Ego and Work: Ego and Pride most of the times become a hindrance when we work inside a team. Take this cue, the first ever Picture post was published. Simple and easy to understand concept. Would want to say, Ego is the biggest enemy to humans. Read Original Post. Success (Perception Vs Reality): Personally, have always thought success is not something the talented achieve with the opportunity presented to them, but success is developed using the opportunity in hand now. In this fast paced world where success is pre-defined and convoluted by metrics it is hard to understand how complex it can sometimes be. So I took a stab at this concept in a simple way. Read Original Post. Doing Vs Saying: As Einstein would describe, Insanity is doing the same thing over and over again and expecting different results. Given the amount of information we get, it is difficult to keep track, learn and implement the same. If you were ever reminded of your college days, there will always be 5-6 people doing different things and we naturally try to emulate what they are doing. This could be from competitive exams GMAT, GRE, CAT, Higher-Ed, B-School hunting etc. Rather than saying you are going to do, it is best to do and then say!!! Read Original Picture Post. Your View Vs Management View: Being in the corporate world can be really demanding and we keep asking this question – “Why me?” when the performance appraisal process ends. In this post I just want to ask you one frank opinion – “Are you really self-critical in your assessments?”. If that is the case there shouldn’t be any heartburns or surprises. If you had just one thing to take back, well forget what others are getting but invest time in making yourself better because that is going to take you longer and further in your career. Read Picture Post. Blogging lifecycle for majority: I am happy and fortunate to be in this blog post because this picture post surely doesn’t apply to SQLAuthority where consistency and persistence have been the hallmark of the blog. For the majority others, who have a tendency to start a blog, get into slumber for a while and write saying they want to get back to blogging, the picture post was specifically done for them. Paradox of being someone else: It is always a dream that we want to become somebody and in this process of doing so, we become nobody. In this constant tussle of lost identity we forget to enjoy the moment that is in front of us. I just depicted this using a simple analogy of our constant struggle to get to the other side, just to realize we missed the wonderful moments. Grass is not greener on the other side, but grass is greener where we water the surface. Read Picture Post. And on the lighter side… Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: About Me, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• Agile Database Techniques: Effective Strategies for the Agile Software Developer – book review

  - by DigiMortal

     Agile development expects mind shift and developers are not the only ones who must be agile. Every chain is as strong as it’s weakest link and same goes also for development teams. Agile Database Techniques: Effective Strategies for the Agile Software Developer by Scott W. Ambler is book that calls also data professionals to be part of agile development. Often are DBA-s in situation where they are not part of application development and later they have to survive large set of applications that all use databases different way. Of course, only some of these applications are not problematic when looking what database server has to do to serve them. I have seen many applications that rape database servers because developers have no clue what is going on in database (~3K queries to database per web application request – have you seen something like this? I have…) Agile Database Techniques covers some object and database design technologies and gives suggestions to development teams about topics they need help or assistance by DBA-s. The book is also good reading for DBA-s who usually are not very strong in object technologies. You can take this book as bridge between these two worlds. I think teams that build object applications that use databases should buy this book and try at least one or two projects out with Ambler’s suggestions. Table of contents Foreword by Jon Kern.

• Things to install on a new machine – revisited

  - by RoyOsherove

  as I prepare to get a new dev machine at work, I write the things I am going to install on it, before writing the first line of code on that machine: Control Freak Tools: Everything Search Engine – a free and amazingly fast search engine for files all over your machine. (just file names, not inside files). This is so fast I use it almost as a replacement for my start menu, but it’s also great for finding those files that get hidden and tucked away in dark places on my system. Ever had a situation where you needed to see exactly how many copies of X.dll were hiding on your machine and where? this tool is perfect for that. Google Chrome. It’s just fast. very fast. and Firefox has become the IE of alternative browsers in terms of speed and memory. Don’t even get me started on IE. TweetDeck – get a complete view of what’s up on twitter Total Commander – my still favorite file manager, over five years now. KatMouse – will scroll any window your hovering on, even if it’s not an active window, when you use scroll the wheel on it. PowerIso or Daemon Tools – for loading up ISO images of discs LogMeIn Ignition – quick access to your LogMeIn computers for online Backup: JungleDisk or BackBlaze KeePass – save important passwords MS Security Essentials – free anti virus that’s quoest and doesn’t make a mess of your system. for home: uTorrent – a torrent client that can read rss feeds (like the ones from ezrss.it ) Camtasia Studio and SnagIt – for recording and capturing the screen, and then adding cool effects on top. Foxit PDF Reader – much faster that adove reader. Toddler Keys (for home) – for when your baby wants to play with your keyboard. Live Writer – for writing blog posts for Lenovo ThinkPads – Lenovo System Update – if you have a “custom” system instead of the one that came built in, this will keep all your lenovo drivers up to date. FileZilla – for FTP stuff All the utils from sysinternals, (or try the live-links) especially: AutoRuns for deciding what’s really going to load at startup, procmon to see what’s really going on with processes in your system   Developer stuff: Reflector. Pure magic. Time saver. See source code of any compiled assembly. Resharper. Great for productivity and navigation across your source code FinalBuilder – a commercial build automation tool. Love it. much better than any xml based time hog out there. TeamCity – a great visual and friendly server to manage continuous integration. powerful features. Test Lint – a free addin for vs 2010 I helped create, that checks your unit tests for possible problems and hints you about it. TestDriven.NET – a great test runner for vs 2008 and 2010 with some powerful features.

• SQL SERVER – Data Pages in Buffer Pool – Data Stored in Memory Cache

  - by pinaldave

  This will drop all the clean buffers so we will be able to start again from there. Now, run the following script and check the execution plan of the query. Have you ever wondered what types of data are there in your cache? During SQL Server Trainings, I am usually asked if there is any way one can know how much data in a table is stored in the memory cache? The more detailed question I usually get is if there are multiple indexes on table (and used in a query), were the data of the single table stored multiple times in the memory cache or only for a single time? Here is a query you can run to figure out what kind of data is stored in the cache. USE AdventureWorks GO SELECT COUNT(*) AS cached_pages_count, name AS BaseTableName, IndexName, IndexTypeDesc FROM sys.dm_os_buffer_descriptors AS bd INNER JOIN ( SELECT s_obj.name, s_obj.index_id, s_obj.allocation_unit_id, s_obj.OBJECT_ID, i.name IndexName, i.type_desc IndexTypeDesc FROM ( SELECT OBJECT_NAME(OBJECT_ID) AS name, index_id ,allocation_unit_id, OBJECT_ID FROM sys.allocation_units AS au INNER JOIN sys.partitions AS p ON au.container_id = p.hobt_id AND (au.type = 1 OR au.type = 3) UNION ALL SELECT OBJECT_NAME(OBJECT_ID) AS name, index_id, allocation_unit_id, OBJECT_ID FROM sys.allocation_units AS au INNER JOIN sys.partitions AS p ON au.container_id = p.partition_id AND au.type = 2 ) AS s_obj LEFT JOIN sys.indexes i ON i.index_id = s_obj.index_id AND i.OBJECT_ID = s_obj.OBJECT_ID ) AS obj ON bd.allocation_unit_id = obj.allocation_unit_id WHERE database_id = DB_ID() GROUP BY name, index_id, IndexName, IndexTypeDesc ORDER BY cached_pages_count DESC; GO Now let us run the query above and observe the output of the same. We can see in the above query that there are four columns. Cached_Pages_Count lists the pages cached in the memory. BaseTableName lists the original base table from which data pages are cached. IndexName lists the name of the index from which pages are cached. IndexTypeDesc lists the type of index. Now, let us do one more experience here. Please note that you should not run this test on a production server as it can extremely reduce the performance of the database. DBCC DROPCLEANBUFFERS This will drop all the clean buffers and we will be able to start again from there. Now run following script and check the execution plan for the same. USE AdventureWorks GO SELECT UnitPrice, ModifiedDate FROM Sales.SalesOrderDetail WHERE SalesOrderDetailID BETWEEN 1 AND 100 GO The execution plans contain the usage of two different indexes. Now, let us run the script that checks the pages cached in SQL Server. It will give us the following output. It is clear from the Resultset that when more than one index is used, datapages related to both or all of the indexes are stored in Memory Cache separately. Let me know what you think of this article. I had a great pleasure while writing this article because I was able to write on this subject, which I like the most. In the next article, we will exactly see what data are cached and those that are not cached, using a few undocumented commands.

• jQuery Context Menu Plugin and Capturing Right-Click

  - by Ben Griswold

  I was thrilled to find Cory LaViska’s jQuery Context Menu Plugin a few months ago. In very little time, I was able to integrate the context menu with the jQuery Treeview.  I quickly had a really pretty user interface which took full advantage of limited real estate.  And guess what.  As promised, the plugin worked in Chrome, Safari 3, IE 6/7/8, Firefox 2/3 and Opera 9.5.  Everything was perfect and I shipped to the Integration Environment. One thing kept bugging though – right clicks aren’t the standard in a web environment. Sure, when one hovers over the treeview node, the mouse changed from an arrow to a pointer, but without help text most users will certainly left-click rather than right. As I was already doubting the design decision, we did some Mac testing.  The context menu worked in Firefox but not Safari.  Damn.  That’s when I started digging into the Madness of Javascript Mouse Events.  Don’t tell, but it’s complicated.  About as close as one can get to capture the right-click mouse event on all major browsers on Windows and Mac is this: if (event.which == null) /* IE case */ button= (event.button < 2) ? "LEFT" : ((event.button == 4) ? "MIDDLE" : "RIGHT"); else /* All others */ button= (event.which < 2) ? "LEFT" : ((event.which == 2) ? "MIDDLE" : "RIGHT"); Yikes.  The content menu code was simply checking if event.button == 2.  No problem.  Cory offers a jQuery Right Click Plugin which I’m sure works for windows but probably not the Mac either.  (Please note I haven’t verified this.) Anyway, I decided to address my UI design concern and the Safari Mac issue in one swoop.  I decided to make the context menu respond to any mouse click event.  This didn’t take much – especially after seeing how Bill Beckelman updated the library to recognize the left click. First, I added an AnyClick option to the library defaults: // Any click may trigger the dropdown and that's okay // See Javascript Madness: Mouse Events – http: //unixpapa.com/js/mouse.html if (o.anyClick == undefined) o.anyClick = false; And then I trigger the context menu dropdown based on the following conditional: if (evt.button == 2 || o.anyClick) { Nothing tricky about that, right?  Finally, I updated my menu setup to include the AnyClick value, if true: $('.member').contextMenu({ menu: 'memberContextMenu', anyClick: true },             function (action, el, pos) {                 … Now the context menu works in “all” environments if you left, right or even middle click.  Download jQuery Context Menu Plugin for Any Click *Opera 9.5 has an option to allow scripts to detect right-clicks, but it is disabled by default. Furthermore, Opera still doesn’t allow JavaScript to disable the browser’s default context menu which causes a usability conflict.

• Manage Your WordPress Blog Comments from Your Windows Desktop

  - by Matthew Guay

  Are you never more than a few steps away from your PC and want to keep up with comments on your blog?  Then here’s how you can stay on top of your WordPress comments right from your desktop. Wp-comment-notifier is a small free app for Windows that lets you easily view, approve, reply to, and delete comments from your WordPress blog.  Whether you have a free WordPress.com blog or are running WordPress on your own server, this tool can keep you connected to your comments.  Unfortunately it only lets you manage comments at one blog, so if manage multiple WordPress-powered sites you may find this a downside.  Otherwise, it works great and helps you stay on top of the conversation at your blog. Get notified with wp-comment-notifier Download the wp-comment-notifier (link below) and install as usual. Run it once it’s installed.  Enter your blog address, username, and password when prompted. Wp-comment-notifier will automatically setup your account and download recent comments. Finally, enter your blog’s name, and click Finish. Review Comments with wp-comment-notifier You can now review your comments directly by double-clicking the new WordPress icon in your system tray.  The window has 3 tabs…comments, pending, and spam.  Select a comment to reply, edit, spam, or delete it directly from your desktop. If you select Edit, then you can edit the HTML of the comment (including links) directly from within the notifier. You can approve or permanently delete any spam messages that are caught by your blog’s spam filter. Whenever new comments come in, you’ll see a tray popup letting you know how many comments are waiting to be approved or are in the spam folder.  Click the popup to open the editor. Now, you can directly approve that pending comment without going to your WordPress admin page.  When you’re done, just press Enter on your Keyboard to post the reply. Or, if you want to reply to the comment, click the reply link and enter your comment in the entry box at the bottom. If you ever want to double-check if there’s any new comments, just right-click on the tray icon and select refresh. Finally, you can change the settings from the Configuration link in the tray button or by clicking the gear button on the bottom of the review window.  You can change how often it checks for new comments, not to start the notifier at system startup, and edit your account information. Conclusion Whether you’re managing your personal blog or administer a site with millions of hits per day, staying on top of the conversation is one of the best ways to build and maintain your audience.  With wp-comment-notifier, you can be sure that you’re always in control of your blogs comments.  This app is especially useful if you review all comments before allowing them to be published.

• Do NOT Change "Copy Local” project references to false, unless understand subsequences.

  - by Michael Freidgeim

  To optimize performance of visual studio build I've found multiple recommendations to change CopyLocal property for dependent dlls to false,e.g. From http://stackoverflow.com/questions/690033/best-practices-for-large-solutions-in-visual-studio-2008 CopyLocal? For sure turn this offhttp://stackoverflow.com/questions/280751/what-is-the-best-practice-for-copy-local-and-with-project-referencesAlways set the Copy Local property to false and enforce this via a custom msbuild stephttp://codebetter.com/patricksmacchia/2007/06/20/benefit-from-the-c-and-vb-net-compilers-perf/BenefitBenefitMy advice is to always set ‘Copy Local’ to falseSome time ago we've tried to change the setting to false, and found that it causes problem for deployment of top-level projects.Recently I've followed the suggestion and changed the settings for middle-level projects. It didn't cause immediate issues, but I was warned by Readify Consultant Colin Savage about possible errors during deploymentsI haven't undone the changes immediately and we found a few issues during testing.There are many scenarios, when you need to have Copy Local’ left to True.The concerns are highlighted in some stack overflow answers, but they have small number of votes.Top-level projects:  set copy local = true.First of all, it doesn't work correctly for top-level projects, i.e. executables or web sites.As pointed in the answer http://stackoverflow.com/a/6529461/52277for all the references in the one at the top set copy local = true.Alternatively you have to change output directory as it's described in http://www.simple-talk.com/dotnet/.net-framework/partitioning-your-code-base-through-.net-assemblies-and-visual-studio-projects/If you set ‘ Copy Local = false’, VS will, unless you tell it otherwise, place each assembly alone in its own .\bin\Debugdirectory. Because of this, you will need to configure VS to place assemblies together in the same directory. To do so, for each VS project, go to VS > Project Properties > Build tab > Output path, and set the Ouput path to ..\bin\Debugfor debug configuration, and ..\bin\Release for release configuration.Second-level  dependencies:  set copy local = true.Another example when copylocal =false fails on run-time, is when top level assembly doesn't directly referenced one of indirect dependencies.E..g. Top-level assembly A has reference to assembly B with copylocal =true, but assembly B has reference to assembly C with copylocal =false. Most likely assembly C will be missing on runtime and will cause errors E.g. http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1Copy local is important for deployment scenarios and tools. As a general rule you should use CopyLocal=True and http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1 Unfortunately there are some quirks and CopyLocal won't necessary work as expected for assembly references in secondary assemblies structured as shown below.MainApp.exe MyLibrary.dll ThirdPartyLibrary.dll (if in the GAC CopyLocal won't copy to MainApp bin folder)This makes xcopy deployments difficult . .Reflection called DLLs  dependencies:  set copy local = true.E.g user can see error "ISystem.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."The fix for the issue is recommended in http://stackoverflow.com/a/6200173/52277"I solved this issue by setting the Copy Local attribute of my project's references to true."In general, the problems with investigation of deployment issues may overweight the benefits of reduced build time. Setting the Copy Local to false without considering deployment issues is not a good idea.

• Using NServiceBus behind a custom web service

  - by Michael Stephenson

  In this post I'd like to talk about an architecture scenario we had recently and how we were able to utilise NServiceBus to help us address this problem. Scenario Cognos is a reporting system used by one of my clients. A while back we developed a web service façade to allow line of business applications to be able to access reports from Cognos to support their various functions. The service was intended to provide access to reports which were quick running reports or pre-generated reports which could be accessed real-time on demand. One of the key aims of the web service was to provide a simple generic interface to allow applications to get any report without needing to worry about the complex .net SDK for Cognos. The web service also supported multi-hop kerberos delegation so that report data could be accesses under the context of the end user. This service was working well for a period of time. The Problem The problem we encountered was that reports were now also required to be available to batch processes. The original design was optimised for low latency so users would enjoy a positive experience, however when the batch processes started to request 250+ concurrent reports over an extended period of time you can begin to imagine the sorts of problems that come into play. The key problems this new scenario caused are: Users may be affected and the latency of on demand reports was significantly slower The Cognos infrastructure was not scaled sufficiently to be able to cope with these long peaks of load From a cost perspective it just isn't feasible to scale the Cognos infrastructure to be able to handle the load when it is only for a couple of hour window each night. We really needed to introduce a second pattern for accessing this service which would support high through-put scenarios. We also had little control over the batch process in terms of being able to throttle its load. We could however make some changes to the way it accessed the reports. The Approach My idea was to introduce a throttling mechanism between the Web Service Façade and Cognos. This would allow the batch processes to push reports requests hard at the web service which we were confident the web service can handle. The web service would then queue these requests and process them behind the scenes and make a call back to the batch application to provide the report once it had been accessed. In terms of technology we had some limitations because we were not able to use WCF or IIS7 where the MSMQ-Activated WCF services could have helped, but we did have MSMQ as an option and I thought NServiceBus could do just the job to help us here. The flow of how this would work was as follows: The batch applications would send a request for a report to the web service The web service uses NServiceBus to send the message to a Queue The NServiceBus Generic Host is running as a windows service with a message handler which subscribes to these messages The message handler gets the message, accesses the report from Cognos The message handler calls back to the original batch application, this is decoupled because the calling application provides a call back url The report gets into the batch application and is processed as normal This approach looks something like the below diagram: The key points are an application wanting to take advantage of the batch driven reports needs to do the following: Implement our call back contract Make a call to the service providing a call back url Provide a correlation ID so it knows how to tie each response back to its request What does NServiceBus offer in this solution So this scenario is not the typical messaging service bus type of solution people implement with NServiceBus, but it did offer the following: Simplified interaction with MSMQ Offered the ability to configure the number of processes working through the queue so we could find a balance between load on Cognos versus the applications end to end processing time NServiceBus offers retries and a way to manage failed messages NServiceBus offers a high availability setup The simple thing is that NServiceBus gave us the platform to build the solution on. We just implemented a message handler which functionally processed a message and we could rely on NServiceBus to do all of the hard work around managing the queues and all of the lower level things that would have took ages to write to any kind of robust level. Conclusion With this approach we were able to deal with a fairly significant performance issue with out too much rework. Hopefully this write up gives people some insight into ideas on how to leverage the excellent NServiceBus framework to help solve integration and high through-put scenarios.

• The dislikes of TDD

  - by andrewstopford

  I enjoy debates about TDD and Brian Harrys blog post is no exception. Brian sounds out what he likes and dislikes about TDD and it's the dislikes I'll focus on. The idea of having unit tests that cover virtually every line of code that I’ve written that I have to refactor every time I refactor my code makes me shudder.  Doing this way makes me take nearly twice as long as it would otherwise take and I don’t feel like I get sufficient benefits from it. Refactoring your tests to match your refactored code sounds like the tests are suffering. Too many hard dependencies with no SOLID concerns are a sure fire reason you would do this. Maybe at the start of a TDD cycle you would need to do this as your design evolves and you remove these dependencies but this should quickly be resolved as you refactor. If you find your self still doing it then stop and look back at your design. Don’t get me wrong, I’m a big fan of unit tests.  I just prefer to write them after the code has stopped shaking a bit.  In fact most of my early testing is “manual”.  Either I write a small UI on top of my service that allows me to plug in values and try it or write some quick API tests that I throw away as soon as I have validated them. The problem with this is that a UI can make assumptions on your code that then just unit test around and very quickly the design becomes bad and you technical debt sweeps in. If you want to blackbox test your code with a UI then do so after your TDD cycles not before. This is probably by biggest issue with a literal TDD interpretation.  TDD says you never write a line of code without a failing test to show you need it.  I find it leads developers down a dangerous path.  Without any help from a methodology, I have met way too many developers in my life that “back into a solution”.  By this, I mean they write something, it mostly works and they discover a new requirement so they tack it on, and another and another and when they are done, they’ve got a monstrosity of special cases each designed to handle one specific scenario.  There’s way more code than there should be and it’s way too complicated to understand. I believe in finding general solutions to problems from which all the special cases naturally derive rather than building a solution of special cases.  In my mind, to do this, you have to start by conceptualizing and coding the framework of the general algorithm.  For me, that’s a relatively monolithic exercise. TDD is an development pratice not a methodology, the danger is that the solution becomes a mass of different things that violate DRY. TDD won't solve these problems, only good communication and practices like pairing will help. Above all else an assumption that TDD replaces a methodology is a mistake, combine it with what ever works for your team\business but only good communication will help. A good naming scheme\structure for folders, files and tests can help you and your team isolate what tests are for what.

• Redirect all access requests to a domain and subdomain(s) except from specific IP address? [closed]

  - by Christopher

  This is a self-answered question... After much wrangling I found the magic combination of mod_rewrite rules so I'm posting here. My scenario is that I have two domains - domain1.com and domain2.com - both of which are currently serving identical content (by way of a global 301 redirect from domain1 to domain2). Domain1 was then chosen to be repurposed to be a 'portal' domain - with a corporate CMS-based site leading off from the front page, and the existing 'retail' domain (domain2) left to serve the main web site. In addition, a staging subdomain was created on domain1 in order to prepare the new corporate site without impinging on the root domain's existing operation. I contemplated just rewriting all requests to domain2 and setting up the new corporate site 'behind the scenes' without using a staging domain, but I usually use subdomains when setting up new sites. Finally, I required access to the 'actual' contents of the domains and subdomains - i.e., to not be redirected like all other visitors - in order that I can develop the new site and test it in the staging environment on the live server, as I'm not using a separate development webserver in this case. I also have another test subdomain on domain1 which needed to be preserved. The way I eventually set it up was as follows: (10.2.2.1 would be my home WAN IP) .htaccess in root of domain1 RewriteEngine On RewriteCond %{REMOTE_ADDR} !^10\.2\.2\.1 RewriteCond %{HTTP_HOST} !^staging.domain1.com$ [NC] RewriteCond %{HTTP_HOST} !^staging2.domain1.com$ [NC] RewriteRule ^(.*)$ http://domain2.com/$1 [R=301] .htaccess in staging subdomain on domain1: RewriteEngine On RewriteCond %{REMOTE_ADDR} !^10\.2\.2\.1 RewriteCond %{HTTP_HOST} ^staging.revolver.coop$ [NC] RewriteRule ^(.*)$ http://domain2.com/$1 [R=301,L] The multiple .htaccess files and multiple rulesets require more processing overhead and longer iteration as the visitor is potentially redirected twice, however I find it to be a more granular method of control as I can selectively allow more than one IP address access to individual staging subdomain(s) without automatically granting them access to everything else. It also keeps the rulesets fairly simple and easy to read. (or re-interpret, because I'm always forgetting how I put rules together!) If anybody can suggest a more efficient way of merging all these rules and conditions into just one main ruleset in the root of domain1, please post! I'm always keen to learn, this post is more my attempt to preserve this information for those who are looking to redirect entire domains for all visitors except themselves (for design/testing purposes) and not just denying specific file access for maintenance mode (there are many good examples of simple mod_rewrite rules for 'maintenance mode' style operation easily findable via Google). You can also extend the IP address detection - firstly by using wildcards ^10\.2\.2\..*: the last octet's \..* denotes the usual "." and then "zero or more arbitrary characters", signified by the .* - so you can specify specific ranges of IPs in a subnet or entire subnets if you wish. You can also use square brackets: ^10\.2\.[1-255]\.[120-140]; ^10\.2\.[1-9]?[0-9]\.; ^10\.2\.1[0-1][0-9]\. etc. The third way, if you wish to specify multiple discrete IP addresses, is to bracket them in the style of ^(1.1.1.1|2.2.2.2|3.3.3.3)$, and you can of course use square brackets to substitute octets or single digits again. NB: if you're using individual RewriteCond lines to specify multiple IPs / ranges, make sure to put [OR] at the end of each one otherwise mod_rewrite will interpret as "if IP address matches 1.1.1.1 AND if IP address matches 2.2.2.2... which is of course impossible! However as far as I'm aware this isn't necessary if you're using the ! negator to specify "and is not...". Kudos also to SE: this older question also came in useful when I was verifying my own knowledge prior to my futzing around with code. This page was helpful, as were the various other links posted below (can't hyperlink them all due to spam protection... other regex checkers are available). The AddedBytes cheat sheet's useful to pin up on your wall.

• Value of SOA Specialization interview with Thomas Schaller IPT - part III

  - by Jürgen Kress

  Recognized by Oracle, Preferred by Customers. We had the great opportunity to interview Thomas Schaller – Partner from our SOA Specialized Partner IPT Innovation Process Technology from Switzerland Why did IPT decide to become SOA Specialized? " SOA Specialization is a great branding for IPT. We are the SOA Specialists in the Swiss market, as we focus all our services around SOA. With 65 Swiss consultants focused on SOA Security & SOA Testing & BPM – Business Process Management & BSM – Business Service Modeling the partnership with Oracle as the technology leader in SOA is key, therefore it was important to us to become the first SOA Specialized company in Switzerland. As a result IPT is mentioned by Gartner as one of eight European SOA Consulting Firms and included in „Guide to SOA Consulting and System Integration Service Providers“ Can you describe the marketing activities with Oracle? Once a year we organize the largest SOA Conference in Switzerland “SOA, BPM & Integration Forum 2011“ Oracle is much more than a sponsor for the conference. Jointly we invite our customer base to attend this key event. The sales teams address jointly their most important prospects and customers. Oracle supports us with key speakers who present future directions of the Oracle SOA portfolio like Clemens Utschig-Utschig who presented details about the Complex Event Processing (CEP) solution in 2009 and James Allerton-Austin who presented details about the social BPM solution (BPM) in 2010. Additional our key customers presented their Oracle SOA success stories. How did you team with Oracle around the sales activities? "Sales alignment is key for the successful partnership. When we achieved! SOA Specialization we celebrated jointly with the Oracle and IPT middleware sales team. At the Aperol may interesting discussions resulted in joint opportunities and business. A key section of our joint business planning are marketing and sales activities. Together we define campaign topics and target customers. Matthias Breitschmid our superb Oracle partner manager ensures that the defined sales teams align and start the joint business. Regular we review our joint business plan with the joint management teams and Jürgen Kress our EMEA Oracle Sponsor. It is great to see that both companies profit from each other and we receive leads from Oracle!” Did you get Oracle support to train your consultants in the Oracle SOA Suite? “Enablement is key for us to deliver successful SOA projects. Together with Ralph Bellinghausen from the Oracle Enablement team we defined an Oracle trainings plan for our consultants. The monthly SOA Partner Community newsletter is a great resource to get the latest product updates, webcasts and trainings. As a SOA Specialized partner we get also invited to the SOA Blackbelt trainings, this trainings are hosted by Oracle product management where we get not only first hand information we get also direct access to the developers who can support us in critical project phases. Driven by the customer success we have increased our Oracle SOA practice by more than 200% in the last years!” Why did the customer decide for the IPT SOA offering? “SOA Specialization becomes a brand for customers, it proofs that we have the certified SOA skills and that IPT has delivered successful Oracle SOA projects. Jointly with Oracle and all the support we get from marketing, sales, enablement, support and product management we can ensure our customers to deliver their SOA project successful!” What are the next steps for IPT? “SOA Specialization is a super beneficial for IPT.

• More SQL Smells

  - by Nick Harrison

  Let's continue exploring some of the SQL Smells from Phil's list. He has been putting together. Datatype mis-matches in predicates that rely on implicit conversion.(Plamen Ratchev) This is a great example poking holes in the whole theory of "If it works it's not broken" Queries will this probably will generally work and give the correct response. In fact, without careful analysis, you probably may be completely oblivious that there is even a problem. This subtle little problem will needlessly complicate queries and slow them down regardless of the indexes applied. Consider this example: CREATE TABLE [dbo].[Page](     [PageId] [int] IDENTITY(1,1) NOT NULL,     [Title] [varchar](75) NOT NULL,     [Sequence] [int] NOT NULL,     [ThemeId] [int] NOT NULL,     [CustomCss] [text] NOT NULL,     [CustomScript] [text] NOT NULL,     [PageGroupId] [int] NOT NULL;  CREATE PROCEDURE PageSelectBySequence ( @sequenceMin smallint , @sequenceMax smallint ) AS BEGIN SELECT [PageId] , [Title] , [Sequence] , [ThemeId] , [CustomCss] , [CustomScript] , [PageGroupId] FROM [CMS].[dbo].[Page] WHERE Sequence BETWEEN @sequenceMin AND @SequenceMax END  Note that the Sequence column is defined as int while the sequence parameter is defined as a small int. The problem is that the database may have to do a lot of type conversions to evaluate the query. In some cases, this may even negate the indexes that you have in place. Using Correlated subqueries instead of a join   (Dave_Levy/ Plamen Ratchev) There are two main problems here. The first is a little subjective, since this is a non-standard way of expressing the query, it is harder to understand. The other problem is much more objective and potentially problematic. You are taking much of the control away from the optimizer. Written properly, such a query may well out perform a corresponding query written with traditional joins. More likely than not, performance will degrade. Whenever you assume that you know better than the optimizer, you will most likely be wrong. This is the fundmental problem with any hint. Consider a query like this:  SELECT Page.Title , Page.Sequence , Page.ThemeId , Page.CustomCss , Page.CustomScript , PageEffectParams.Name , PageEffectParams.Value , ( SELECT EffectName FROM dbo.Effect WHERE EffectId = dbo.PageEffects.EffectId ) AS EffectName FROM Page INNER JOIN PageEffect ON Page.PageId = PageEffects.PageId INNER JOIN PageEffectParam ON PageEffects.PageEffectId = PageEffectParams.PageEffectId  This can and should be written as:  SELECT Page.Title , Page.Sequence , Page.ThemeId , Page.CustomCss , Page.CustomScript , PageEffectParams.Name , PageEffectParams.Value , EffectName FROM Page INNER JOIN PageEffect ON Page.PageId = PageEffects.PageId INNER JOIN PageEffectParam ON PageEffects.PageEffectId = PageEffectParams.PageEffectId INNER JOIN dbo.Effect ON dbo.Effects.EffectId = dbo.PageEffects.EffectId  The correlated query may just as easily show up in the where clause. It's not a good idea in the select clause or the where clause. Few or No comments. This one is a bit more complicated and controversial. All comments are not created equal. Some comments are helpful and need to be included. Other comments are not necessary and may indicate a problem. I tend to follow the rule of thumb that comments that explain why are good. Comments that explain how are bad. Many people may be shocked to hear the idea of a bad comment, but hear me out. If a comment is needed to explain what is going on or how it works, the logic is too complex and needs to be simplified. Comments that explain why are good. Comments may explain why the sql is needed are good. Comments that explain where the sql is used are good. Comments that explain how tables are related should not be needed if the sql is well written. If they are needed, you need to consider reworking the sql or simplify your data model. Use of functions in a WHERE clause. (Anil Das) Calling a function in the where clause will often negate the indexing strategy. The function will be called for every record considered. This will often a force a full table scan on the tables affected. Calling a function will not guarantee that there is a full table scan, but there is a good chance that it will. If you find that you often need to write queries using a particular function, you may need to add a column to the table that has the function already applied.

• Tough Decisions

  - by Johnm

  There was once a thriving business that employed two Database Administrators, Sam and Jim. Both DBAs were certified, educated and highly talented in their skill sets. During lunch breaks these two DBAs were often found together discussing best practices, troubleshooting techniques and the latest release notes for the upcoming version of SQL Server. They genuinely loved what they did. The maintenance of the first database was the responsibility of Sam. He was the architect of this server's setup and he was very meticulous in its configuration. He regularly monitored the health of the database, validated backup files and regularly adhered to the best practices that were advocated by well respected professionals. He was very proud of the fact that there was never a database that he managed that lost data or performed poorly. The maintenance of the second database was the responsibility of Jim. He too was the architect of this server's setup. At the time that he built this server, his understanding of the finer details of configuration were not as clear as they are today. The server was build on a shoestring budget and with very little time for testing and implementation. Jim often monitored the health of the database; but in more of a reactionary mode due to user complaints of slowness or failed transactions. Deadlocks abounded and the backup files were never validated. One day, the announcement was made that revealed that the business had hit financially hard times. Budgets were being cut, limitation on spending was implemented and the reduction in full-time staff was required. Since having two DBAs was regarded a luxury by many, this meant that either Sam or Jim were about to find themselves out of a job. Sam and Jim's boss, Frank, was faced with a very tough decision. Sam's performance was flawless. His techniques and practices were perfection. The databases he managed were reliable and efficient. His solutions are "by the book". When given a task it is certain that, while it may take a little longer, it will be done right the first time. Jim's techniques and practices were not perfect; but effective and responsive. He made mistakes regularly; but he shows that he learns from them and they often result in innovative solutions. When given a task it is certain that, while the results may require some tweaking, it will be done on time and under budget. You are Frank's best friend. He approaches you and presents this scenario. He must layoff one of his valued DBAs the very next morning. Frank asks you: "All else being equal, who would you let go? and Why?" Another pertinent question is raised: "Regardless of good times or bad, if you had to choose, which DBA would you want on your team when tough challenges arise?" Your response is.

• How SQL Server 2014 impacts Red Gate’s SQL Compare

  - by Michelle Taylor

  SQL Compare 10.7 successfully connects to SQL Server 2014, but it doesn’t yet cover the SQL Server 2014 features which would require us to make major changes to SQL Compare to support. In this post I’m going to talk about the SQL Server 2014 features we’ve already begun supporting, and which ones we’re working on for the next release of SQL Compare (v11). From SQL Compare’s perspective, the new memory-optimized table functionality (some might know it as ‘Hekaton’) has been the most important change. It can’t be described as its own object type, but the new functionality is split across two existing object types (three if you count indexes), as it also comes with native stored procedures and inline indexes. Along with connectivity support, the SQL Compare team has already implemented the first part of the puzzle – inline specification of indexes. These are essential for memory-optimized tables because it’s not possible to alter the memory optimized table’s structure, and so indexes can’t be added after the fact without dropping the table. Books Online  shows this in more detail in the table_index and column_index clauses of http://msdn.microsoft.com/en-us/library/ms174979(v=sql.120).aspx. SQL Compare 10.7 currently supports reading the new inline index specification from script folders and source control repositories, and will write out inline indexes where it’s necessary to do so (i.e. in UDDTs or when attempting to write projects compatible with the SSDT database project format). However, memory-optimized tables themselves are not yet supported in 10.7. The team is actively working on making them available in the v11 release with full support later in the year, and in a beta version before that. Fortunately, SQL Compare already has some ways of handling tables that have to be dropped and created rather than altered, which are being adapted to handle this new kind of table. Because it’s one of the largest new database engine features, there’s an equally large Books Online section on memory-optimized tables, but for us the most important parts of the documentation are the normal table features that are changed or unsupported and the new syntax found in the T-SQL reference pages. We are treating SQL Compare’s support of Natively Compiled Stored Procedures as a separate unit of work, which will be available in a subsequent beta and also feed into the v11 release. This new type of stored procedure is designed to work with memory-optimized tables to maintain the performance improvements gained by them – but you can still also access memory-optimized tables from normal stored procedures and ad-hoc queries. To us, they’re essentially a limited-syntax stored procedure with a few extra options in the create statement, embodied in the updated CREATE PROCEDURE documentation and with the detailed limitations. They should be easier to handle than memory-optimized tables simply because the handling of stored procedures is less sensitive to dropping the object than the handling of tables. However, both share an incompatibility with DDL triggers and Event Notifications which mean we’ll need to temporarily disable these during the specific deployment operations that involve them – don’t worry, we’ll supply a warning if this is the case so that you can check your auditing arrangements can handle the situation. There are also a handful of other improvements in SQL Server 2014 which affect SQL Compare and SQL Data Compare that are not connected to memory optimized tables. The largest of these are the improvements to columnstore indexes, with the capability to create clustered columnstore indexes and update columnstore tables through them – for more detail, take a look at the new syntax reference. There’s also a new index option for better compression of columnstores (COLUMNSTORE_ARCHIVE) and a new statistics option for incremental per-partition statistics, plus the 90 compatibility level is being retired. We’re planning to finish up these small clean-up features last, and be ready to release SQL Compare 11 with full SQL 2014 support early in Q3 this year. For a more thorough overview of what’s new in SQL Server 2014, Books Online’s What’s New section is a good place to start (although almost all the changes in this version are in the Database Engine).
