  • T-SQL Tuesday #31 - Logging Tricks with CONTEXT_INFO

    - by Most Valuable Yak (Rob Volk)
    This month's T-SQL Tuesday is being hosted by Aaron Nelson [b | t], fellow Atlantan (the city in Georgia, not the famous sunken city, or the resort in the Bahamas) and covers the topic of logging (the recording of information, not the harvesting of trees) and maintains the fine T-SQL Tuesday tradition begun by Adam Machanic [b | t] (the SQL Server guru, not the guy who fixes cars, check the spelling again, there will be a quiz later). This is a trick I learned from Fernando Guerrero [b | t] waaaaaay back during the PASS Summit 2004 in sunny, hurricane-infested Orlando, during his session on Secret SQL Server (not sure if that's the correct title, and I haven't used parentheses in this paragraph yet).  CONTEXT_INFO is a neat little feature that's existed since SQL Server 2000 and perhaps even earlier.  It lets you assign data to the current session/connection, and maintains that data until you disconnect or change it.  In addition to the CONTEXT_INFO() function, you can also query the context_info column in sys.dm_exec_sessions, or even sysprocesses if you're still running SQL Server 2000, if you need to see it for another session. While you're limited to 128 bytes, one big advantage that CONTEXT_INFO has is that it's independent of any transactions.  If you've ever logged to a table in a transaction and then lost messages when it rolled back, you can understand how aggravating it can be.  CONTEXT_INFO also survives across multiple SQL batches (GO separators) in the same connection, so for those of you who were going to suggest "just log to a table variable, they don't get rolled back":  HA-HA, I GOT YOU!  Since GO starts a new batch all variable declarations are lost. Here's a simple example I recently used at work.  I had to test database mirroring configurations for disaster recovery scenarios and measure the network throughput.  I also needed to log how long it took for the script to run and include the mirror settings for the database in question.  I decided to use AdventureWorks as my database model, and Adam Machanic's Big Adventure script to provide a fairly large workload that's repeatable and easily scalable.  My test would consist of several copies of AdventureWorks running the Big Adventure script while I mirrored the databases (or not). Since Adam's script contains several batches, I decided CONTEXT_INFO would have to be used.  As it turns out, I only needed to grab the start time at the beginning, I could get the rest of the data at the end of the process.   The code is pretty small: declare @time binary(128)=cast(getdate() as binary(8)) set context_info @time   ... rest of Big Adventure code ...   go use master; insert mirror_test(server,role,partner,db,state,safety,start,duration) select @@servername, mirroring_role_desc, mirroring_partner_instance, db_name(database_id), mirroring_state_desc, mirroring_safety_level_desc, cast(cast(context_info() as binary(8)) as datetime), datediff(s,cast(cast(context_info() as binary(8)) as datetime),getdate()) from sys.database_mirroring where db_name(database_id) like 'Adv%';   I declared @time as a binary(128) since CONTEXT_INFO is defined that way.  I couldn't convert GETDATE() to binary(128) as it would pad the first 120 bytes as 0x00.  To keep the CAST functions simple and avoid using SUBSTRING, I decided to CAST GETDATE() as binary(8) and let SQL Server do the implicit conversion.  It's not the safest way perhaps, but it works on my machine. :) As I mentioned earlier, you can query system views for sessions and get their CONTEXT_INFO.  With a little boilerplate code this can be used to monitor long-running procedures, in case you need to kill a process, or are just curious  how long certain parts take.  In this example, I added code to Adam's Big Adventure script to set CONTEXT_INFO messages at strategic places I want to monitor.  (His code is in UPPERCASE as it was in the original, mine is all lowercase): declare @msg binary(128) set @msg=cast('Altering bigProduct.ProductID' as binary(128)) set context_info @msg go ALTER TABLE bigProduct ALTER COLUMN ProductID INT NOT NULL GO set context_info 0x0 go declare @msg1 binary(128) set @msg1=cast('Adding pk_bigProduct Constraint' as binary(128)) set context_info @msg1 go ALTER TABLE bigProduct ADD CONSTRAINT pk_bigProduct PRIMARY KEY (ProductID) GO set context_info 0x0 go declare @msg2 binary(128) set @msg2=cast('Altering bigTransactionHistory.TransactionID' as binary(128)) set context_info @msg2 go ALTER TABLE bigTransactionHistory ALTER COLUMN TransactionID INT NOT NULL GO set context_info 0x0 go declare @msg3 binary(128) set @msg3=cast('Adding pk_bigTransactionHistory Constraint' as binary(128)) set context_info @msg3 go ALTER TABLE bigTransactionHistory ADD CONSTRAINT pk_bigTransactionHistory PRIMARY KEY NONCLUSTERED(TransactionID) GO set context_info 0x0 go declare @msg4 binary(128) set @msg4=cast('Creating IX_ProductId_TransactionDate Index' as binary(128)) set context_info @msg4 go CREATE NONCLUSTERED INDEX IX_ProductId_TransactionDate ON bigTransactionHistory(ProductId,TransactionDate) INCLUDE(Quantity,ActualCost) GO set context_info 0x0   This doesn't include the entire script, only those portions that altered a table or created an index.  One annoyance is that SET CONTEXT_INFO requires a literal or variable, you can't use an expression.  And since GO starts a new batch I need to declare a variable in each one.  And of course I have to use CAST because it won't implicitly convert varchar to binary.  And even though context_info is a nullable column, you can't SET CONTEXT_INFO NULL, so I have to use SET CONTEXT_INFO 0x0 to clear the message after the statement completes.  And if you're thinking of turning this into a UDF, you can't, although a stored procedure would work. So what does all this aggravation get you?  As the code runs, if I want to see which stage the session is at, I can run the following (assuming SPID 51 is the one I want): select CAST(context_info as varchar(128)) from sys.dm_exec_sessions where session_id=51   Since SQL Server 2005 introduced the new system and dynamic management views (DMVs) there's not as much need for tagging a session with these kinds of messages.  You can get the session start time and currently executing statement from them, and neatly presented if you use Adam's sp_whoisactive utility (and you absolutely should be using it).  Of course you can always use xp_cmdshell, a CLR function, or some other tricks to log information outside of a SQL transaction.  All the same, I've used this trick to monitor long-running reports at a previous job, and I still think CONTEXT_INFO is a great feature, especially if you're still using SQL Server 2000 or want to supplement your instrumentation.  If you'd like an exercise, consider adding the system time to the messages in the last example, and an automated job to query and parse it from the system tables.  That would let you track how long each statement ran without having to run Profiler. #TSQL2sDay

  • Silverlight Cream for March 14, 2011 -- #1060

    - by Dave Campbell
    In this Issue: Lazar Nikolov, Rudi Grobler, WindowsPhoneGeek, Jesse Liberty, Pete Brown, Jessica Foster, Chris Rouw, Andy Beaulieu, and Colin Eberhardt. Above the Fold: Silverlight: "A Silverlight Resizable TextBlock (and other resizable things)" Colin Eberhardt WP7: "Retrofitting the Trial API" Jessica Foster Shoutouts: Rudi Grobler has a post up that's not Silverlight, but it's cool stuff you may be interested in: WPF Themes now available on NuGet From SilverlightCream.com: Simulating rain in Silverlight Lazar Nikolov has a cool tutorial up at SilverlightShow... Simulating rain. Nice demo near to top, and source code plus a very nice tutorial on the entire process. Making the ApplicationBar bindable Rudi Grobler has a couple new posts up... first this one on making the WP7 AppBar bindable... he's created 2 simple wrappers that make it possible to bind to a method... with source as usual! All about Splash Screens in WP7 – Creating animated Splash Screen WindowsPhoneGeek's latest is about splash screens in WP7, but he goes one better with animated splash screens. Lots of good information including closing points in more of a FAQ-style listing. Testing Network Availability Jesse Liberty's latest is on testing for network availability in your WP7 app. This should be required reading for anyone building a WP7 app, since you never know when the network is going to be there or not. Lighting up on Windows 7 with Native Extensions for Microsoft Silverlight Pete Brown's latest post is about the Native Extensions for Microsoft Silverlight or NESL library. Pete describes what NESL is, a link to the library, installing it, and tons more information. If you wanna know or try NESL... this looks like the place to start. Retrofitting the Trial API Jessica Foster paused on the way to shipping her WP7 app to add in the trial API code. Check out what she went through to complete that task, as she explains the steps and directions she took. Good description, links, and code. WP7 Insights #2: Creating a Splash Screen in WP7 In the 2nd post in his series on WP7 development, Chris Rouw is discussing a WP7 splash screen. He gives some good external links for references then gets right into discussing his code. Air Hockey for Windows Phone 7 Andy Beaulieu shares a tutorial he wrote for the Expression Toolbox site, using the Physics Helper Library and Farseer Physics Engine -- an Air Hockey game for WP7. A Silverlight Resizable TextBlock (and other resizable things) I think Michael Washington had the best comment about Colin Eberhardt's latest outing: "Another WOW example" ... drop this in the pretty darn cool category: an attached behavior that uses a Thumb control within a popup to adorn any UI element to allow the user to resize it!

  • Frustrated where I am, but not sure where to go with my career [closed]

    - by Tom Pickles
    I work (3 years now) as a lead developer for a team developing internal tools and websites for a customer account within large outsourcing company. I'm a self taught programmer and my previous incarnation was a 3rd line support guy, so I have a solid infrastructure knowledge. We use VB.Net/MSSQL/SSIS/SSRS ASP.NET (nTier) in house and I have about 8 years coding experience. Without going into too much detail, my boss is very ambitious and uses our team as his footing to get up the ladder. I've been in the team from the start and the only new dev's we have brought in have been people with a bit of VBA/VBScript experience, much to my chagrin, to bolster his empire. It's been a lot of hard work to bring them up to a standard, but there's still a lot for them to learn. This makes my life stressful as I always get the high profile/complex project work to do as other's simply cannot do it, or it'd take them twice/three times longer to do it. My boss is always seeking stuff for us to build for people who haven't asked for it, which usually get's thrown to me as I have the most experience and can pick new API's (etc) up quicker. He doesn't give us proper requirements, we don't get time to design properly before we code, he wants us to throw something (quick and dirty as he calls it) together so we can get it out ASAP. I take pride in my work so I like to do it properly, make my code clean, maintainable etc, and I train the other guys in the team to do the same. But, we always fall on our faces. The customer we drop the apps on say it doesn't do what they need (due to few requirements), or my boss doesn't like it/changes the spec, so we have to rework it, it get's drawn out, and it makes us and me look and feel like fools. We then get accused by boss of not being reactive enough to change. I've had enough. In order to get my skills and knowledge gap's filled, I've been reading Code Complete 2nd Ed (McConnell) and the Head First Design Patterns books. I'm forcing myself to move into C# from VB at home to broaden my horizons. I'm not sure where to go from here. I don't want to code all my life as I'd like to move into a higher level design/architects role at some point in time (I'm 35). Where do I/can I go from here?

  • Detecting if someone is in a room in your house and sending you an email.

    - by mbcrump
    Let me setup this scenario: You are selling your house. You have small children. (Possibly 2 rug rats or more) The real estate company calls and says they have a showing for your house between the hours of 3pm-6pm. You have to keep the children occupied. You realize this is the 5th time you have shown your house this week. What is a programmer to do?……Setup a webcam, find a motion detection software that has support to launch a program and of course, Visual Studio 2010. First, comes the tools Some sort of webcam, I chose the WinBook because a friend of mine loaned it to me. It is a basic USB2.0 camera that supports 640x480 without software.  Next up was find webcam software that supports launching a program. WebcamXP support this. VS 2010 Console Application. A cell phone that you can check your email. You may be asking, why write code to send the email when a lot of commercial software motion detection packages include that as base functionality. Well, first it cost money and second I don’t want the picture of the person as that probably invades privacy and as a future buyer, I don’t want someone recording me in their house. Now onto the show... First, the code part. We are going to create a VS2010 or whatever version you have installed and use the following code snippet. Code Snippet using System; using System.Net.Mail; using System.Net;     namespace MotionDetectionEmailer {     class Program     {         static void Main(string[] args)         {             try             {                 MailMessage m = new MailMessage                    ("[email protected]",                     "[email protected]",                     "Motion Detected at " + DateTime.Now,                     "Someone is in the downstairs basement.");                 SmtpClient client = new SmtpClient("smtp.charter.net");                 client.Credentials = new NetworkCredential("mbcrump", "NOTTELLINGYOU");                 client.Send(m);             }               catch (SmtpException ex)             {                 Console.WriteLine("Who cares?? " + ex.ToString());             }         }       } } Second, Download and install wecamxp and select the option to launch an external program and you are finished. Now, when you are at MCDonalds and can check your email on your phone, you will see when they entered the house and you can go back home without waiting the full 3 hours. --- NICE!

  • how to send trackback and pingback using c# script

    - by anirudha
    This is a very interesting topic because if you want to search about them. you find much useless stuff even you use c# as prefix. 1. how trackback works ? Every blog who have support to trackback that in their every post they have some text comment like <rdf:/rdf></rdf:rdf>  inside this tag the attribute “trackback:ping” have a url where we can send trackback. 2. you need some information about your blog to post where you want to trackback like 1. URL where you want to send the trackback 2. your post title [may be page title] 3. your post URL [may be page url] 4.  Excerpt : information you want to send. 5. you blogname [may be sitename if you use site not blog] make the information like querystring just we use in asp.net ex: title=”pingpost&url=pingurl&excerpt=it’s me&blog=myblog” ; the information look like asp.net Querystring if you unsure that you can HTMLencode the information who you use in parameters. you need to be sure that your post have URL of post where you want to send trackback. make  a request to pingurl set the following property request.Method = “POST”; //because they support only POST request.ContentLength = param.length // choose the length of parameters we create for sending ping. request.ContentType = "application/x-www-form-urlencoded"; // required to set. now when you send the request then server respond you something about your request check that the request.statuscode is verify that’s work or not if (response.StatusCode < HttpStatusCode.OK && response.StatusCode >= HttpStatusCode.Ambiguous)                     throw new Exception(string.Format(response.StatusCode.ToString())); because you have the response in XML format you can parse the response that’s have Error tag inside them or not. i put here information not code the reason is that “i see some other blog from a week on the topic but i found that they[blogger] post code not the method and all their code are useless and not worked”. because i thing to be more declarative i post here the definition not code.

  • Working With Extended Events

    - by Fatherjack
    SQL Server 2012 has made working with Extended Events (XE) pretty simple when it comes to what sessions you have on your servers and what options you have selected and so forth but if you are like me then you still have some SQL Server instances that are 2008 or 2008 R2. For those servers there is no built-in way to view the Extended Event sessions in SSMS. I keep coming up against the same situations – Where are the xel log files? What events, actions or predicates are set for the events on the server? What sessions are there on the server already? I got tired of this being a perpetual question and wrote some TSQL to save as a snippet in SQL Prompt so that these details are permanently only a couple of clicks away. First, some history. If you just came here for the code skip down a few paragraphs and it’s all there. If you want a little time to reminisce about SQL Server then stick with me through the next paragraph or two. We are in a bit of a cross-over period currently, there are many versions of SQL Server but I would guess that SQL Server 2008, 2008 R2 and 2012 comprise the majority of installations. With each of these comes a set of management tools, of which SQL Server Management Studio (SSMS) is one. In 2008 and 2008 R2 Extended Events made their first appearance and there was no way to work with them in the SSMS interface. At some point the Extended Events guru Jonathan Kehayias (http://www.sqlskills.com/blogs/jonathan/) created the SQL Server 2008 Extended Events SSMS Addin which is really an excellent tool to ease XE session administration. This addin will install in SSMS 2008 or 2008R2 but not SSMS 2012. If you use a compatible version of SSMS then I wholly recommend downloading and using it to make your work with XE much easier. If you have SSMS 2012 installed, and there is no reason not to as it will let you work with all versions of SQL Server, then you cannot install this addin. If you are working with SQL Server 2012 then SSMS 2012 has built in functionality to manage XE sessions – this functionality does not apply for 2008 or 2008 R2 instances though. This means you are somewhat restricted and have to use TSQL to manage XE sessions on older versions of SQL Server. OK, those of you that skipped ahead for the code, you need to start from here: So, you are working with SSMS 2012 but have a SQL Server that is an earlier version that needs an XE session created or you think there is a session created but you aren’t sure, or you know it’s there but can’t remember if it is running and where the output is going. How do you find out? Well, none of the information is hidden as such but it is a bit of a wrangle to locate it and it isn’t a lot of code that is unlikely to remain in your memory. I have created two pieces of code. The first examines the SYS.Server_Event_… management views in combination with the SYS.DM_XE_… management views to give the name of all sessions that exist on the server, regardless of whether they are running or not and two pieces of TSQL code. One piece will alter the state of the session: if the session is running then the code will stop the session if executed and vice versa. The other piece of code will drop the selected session. If the session is running then the code will stop it first. Do not execute the DROP code unless you are sure you have the Create code to hand. It will be dropped from the server without a second chance to change your mind. /**************************************************************/ /***   To locate and describe event sessions on a server    ***/ /***                                                        ***/ /***   Generates TSQL to start/stop/drop sessions           ***/ /***                                                        ***/ /***        Jonathan Allen - @fatherjack                    ***/ /***                 June 2013                                ***/ /***                                                        ***/ /**************************************************************/ SELECT  [EES].[name] AS [Session Name - all sessions] ,         CASE WHEN [MXS].[name] IS NULL THEN ISNULL([MXS].[name], 'Stopped')              ELSE 'Running'         END AS SessionState ,         CASE WHEN [MXS].[name] IS NULL              THEN ISNULL([MXS].[name],                          'ALTER EVENT SESSION [' + [EES].[name]                          + '] ON SERVER STATE = START;')              ELSE 'ALTER EVENT SESSION [' + [EES].[name]                   + '] ON SERVER STATE = STOP;'         END AS ALTER_SessionState ,         CASE WHEN [MXS].[name] IS NULL              THEN ISNULL([MXS].[name],                          'DROP EVENT SESSION [' + [EES].[name]                          + '] ON SERVER; -- This WILL drop the session.

It is possible to recreate the sessions but that is a whole lot of aggravation I’d rather avoid.

  • Should I choose Doctrine 2 or Propel 1.5/1.6, and why?

    - by Billy ONeal
    I'd like to hear from those who have used Doctrine 2 (or later) and Propel 1.5 (or later). Most comparisons between these two object relational mappers are based on old versions -- Doctrine 1 versus Propel 1.3/1.4, and both ORMs went through significant redesigns in their recent revisions. For example, most of the criticism of Propel seems to center around the "ModelName Peer" classes, which are deprecated in 1.5 in any case. Here's what I've accumulated so far (And I've tried to make this list as balanced as possible...): Propel Pros Extremely IDE friendly, because actual code is generated, instead of relying on PHP magic methods. This means IDE features like code completion are actually helpful. Fast (In terms of database usage -- no runtime introspection is done on the database) Clean migration between schema versions (at least in the 1.6 beta) Can generate PHP 5.3 models (i.e. namespaces) Easy to chain a lot of things into a single database query with things like useXxx methods. (See the "code completion" video above) Cons Requires an extra build step, namely building the model classes. Generated code needs rebuilt whenever Propel version is changed, a setting is changed, or the schema changes. This might be unintuitive to some and custom methods applied to the model are lost. (I think?) Some useful features (i.e. version behavior, schema migrations) are in beta status. Doctrine Pros More popular Doctrine Query Language can express potentially more complicated relationships between data than easily possible with Propel's ActiveRecord strategy. Easier to add reusable behaviors when compared with Propel. DocBlock based commenting for building the schema is embedded in the actual PHP instead of a separate XML file. Uses PHP 5.3 Namespaces everywhere Cons Requires learning an entirely new programming language (Doctrine Query Language) Implemented in terms of "magic methods" in several places, making IDE autocomplete worthless. Requires database introspection and thus is slightly slower than Propel by default; caching can remove this but the caching adds considerable complexity. Fewer behaviors are included in the core codebase. Several features Propel provides out of the box (such as Nested Set) are available only through extensions. Freakin' HUGE :) This I have gleaned though only through reading the documentation available for both tools -- I've not actually built anything yet. I'd like to hear from those who have used both tools though, to share their experience on pros/cons of each library, and what their recommendation is at this point :)
