  • Stack Overflow works best with JavaScript enabled banner

    - by carpenter
    I am trying to mimic this site's Javascipt required banner, and have the below divs which are being hidden if javascript is allowed/enabled, but I am getting a flash/glimps of it on page load. <div id="Main_noJS">Craftystuff.com works best with JavaScript enabled</div> <div id="PartOfMain_noJS"><br /></div> CSS: #Main_noJS { width: 100%; height: 23px; font-family: Arial; font-size: 111%; color: White; font-weight: bold; background: #AE0000; text-align: center; padding-top: 4px; position: fixed; z-index: 100; } JavaScript: // hide the "Craftystuff.com works best with JavaScript enabled" banner, if JavaScript is working if ($("#Main_noJS")) { $("#Main_noJS").hide(); // hide the spacer between the main content and banner... $("#PartOfMain_noJS").hide(); } So the banner is visible to start with, and only when javascript is enabled do I hide it but javascript must take a second to get to work to hide things... I would like to try to stop the glimps of the banner, when the page first loads, any help?

  • Is there a good way of automatically generating javascript client code from server side python

    - by tat.wright
    I basically want to be able to: Write a few functions in python (with the minimum amount of extra meta data) Turn these functions into a web service (with the minimum of effort / boiler plate) Automatically generate some javascript functions / objects for rpc (this should prevent me from doing as many stupid things as possible like mistyping method names, forgetting the names of methods, passing the wrong number of arguments) Example python: def hello_world(): return "Hello world" javascript: ... <!-- This file is automatically generated (either dynamically or statically) --> <script src="http://myurl.com/webservice/client_side_javascript"> </script> ... <script> $('#button').click(function () { hello_world(function (data){ $('#label').text(data))) } </script> A bit of research has shown me some approaches that come close to this: Automatic generation of json-rpc services from functions with a little boiler plate code in python and then using jquery and json to do the calls (still easy to make mistakes with method names - still need to be aware of urls when calling, very irritating to write these calls yourself in the firebug shell) Using a library like soaplib to generate wsdl from python (by adding copious type information). And then somehow convert this into javascript (not sure if there is even a library to do this) But are there any approaches closer to what I want?

  • MVC2 Client-Side Validation for injected Ajax response

    - by radu-negrila
    Hi, I have the following scenario for an MVC 2 website. The user checks a radio. I make a jQuery GET to retrieve some html (partial view + view model). The view-model is annotated with validation attributes. I need client-side validation for the new html's inputs. I tried placing the following line in the partial view: <% Html.EnableClientValidation(); % I was naive. Also for the obtained html I use jQuery's .html to populate my placeholder, which also would execute the javascript. Not that there is any. Is is possible to update the page's validation logic and metadata after the ajax call ? Any ideas (beside remote client side validation) ? Thanks in advance.

  • Stacking two pictures with captions side by side and centered in Wordpress

    - by Jim
    Hi all - this is driving me absolutely nuts. I'm not the most experienced with CSS, so I'm hoping it is something simple. I'm running Wordpress 2.9.2 with "The Morning After" theme. I am trying to write a post where I want to display two small pictures, with captions, side-by-side and centered in the middle of the page. Here is the HTML code I am using to display the images: [caption align="alignnone" width="150" caption="Protein rest"] <a href="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest.jpg"> <img title="Mash during protein rest" src="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest-150x144.jpg" alt="Mash during protein rest" width="150" height="144" /> </a>[/caption] [caption align="alignnone" width="143" caption="Saccharification rest" captionalign="center"] <a href="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest.jpg"> <img title="Mash during saccharification rest" src="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest-143x150.jpg" alt="Mash during saccharification rest" width="143" height="150" /> </a>[/caption] I tried using "aligncenter" and "alignleft" for the caption align - if I use "alignleft" the pictures are lined up perfectly, but all the way to the left of the page. If I use "aligncenter" the pics are in the center, but stacked one on top of the other. My first thought was to wrap the images in a div using: <div style="text-align:center;">image code</div> but that doesn't work. Now, if I wrap in a centered div like that and omit the [caption] tags, it works, but I need the captions. Those caption tags are translated by Wordpress into it's own div of class wp-caption. I've also tried wrapping each separate image in its own div within a parent centered div wrapper. Here is the pertinent parts of the style.css - please let me know if you need any other info, and if you can help me, I will postpone jumping off the nearest bridge! Thanks!! Style.css: .aligncenter, div.aligncenter { display: block; margin: 14px auto; } .alignleft { float: left; margin: 0 14px 10px 0; } .alignright { float: right; margin: 0 0 10px 14px; } .wp-caption { border: 1px solid #ddd; text-align: center; background-color: #f3f3f3; padding-top: 4px; /* optional rounded corners for browsers that support it */ -moz-border-radius: 3px; -khtml-border-radius: 3px; -webkit-border-radius: 3px; border-radius: 3px; } .wp-caption img { margin: 0; padding: 0; border: 0 none; } .wp-caption p.wp-caption-text { font-size: 11px; line-height: 14px; padding: 5px 4px 5px 5px; margin: 0; } PS - I am aware of the Gallery feature available in Wordpress, but would like to avoid it and would love to understand why wrapping in a div doesn't move the whole kit to the center. Finally, just for the sake of completeness, here is the source of the page when loaded using the div wrapper and image code as above (so you can see how Wordpress translates the caption tags): <div style="text-align:center;"> <div class="wp-caption alignnone" style="width: 160px"> <a href="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest.jpg"> <img title="Mash during protein rest" src="http://www.mysite.com/wp-content/uploads/2008/06/protein-rest-150x144.jpg" alt="Mash during protein rest" width="150" height="144" /> </a> <p class="wp-caption-text" style="text-align:center">Protein rest</p> </div> <div class="wp-caption alignnone" style="width: 153px"> <a href="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest.jpg"> <img title="Mash during saccharification rest" src="http://www.mysite.com/wp-content/uploads/2008/06/saccharification-rest-143x150.jpg" alt="Mash during saccharification rest" width="143" height="150" /> </a> <p class="wp-caption-text" style="text-align:center">Saccharification rest</p> </div> </div>

  • Should XML be used server-side, and JSON client-side?

    - by Michel Carroll
    As a personal project, I'm making an AJAX chatroom application using XML as a server-side storage, and JSON for client-side processing. Here's how it works: AJAX Request gets sent to PHP using GET (chat messages/logins/logouts) PHP fetches/modifies the XML file on the server PHP encodes the XML into JSON, and sends back JSON response Javascript handles JSON information (chat messages/logins/logouts) I want to eventually make this a larger-scale chatroom application. Therefore, I want to make sure it's fast and efficient. Was this a bad design choice? In this case, is switching between XML and JSON ok, or is there a better way?

  • Time to start a counter on client-side.

    - by Felipe
    Hi everybody, I'm developing an web application using asp.net mvc, and i need to do a stopwatch (chronometer) (with 30 seconds preprogrammed to start in a certain moment) on client-side using the time of the server, by the way, the client's clock can't be as the server's clock. So, i'm using Jquery to call the server by JSon and get the time, but it's very stress because each one second I call the server to get time, something like this: $(function() { GetTimeByServer(); }); function GetTimeByServer() { $.getJSon('/Home/Time', null, function(result) { if (result.SecondsPending < 30) { // call another function to start an chronometer } else { window.SetTimeout(GetTimeByServer, 1000); //call again each 1 second! } }); } It works fine, but when I have more than 3 or 4 call like this, the browser slowly but works! I'd like to know, how improve more performace in client side, or if is there any way to do this... is there any way to client listen the server like a "socket" to know if the chronometer should start... PS: Sorry for my english! thanks Cheers

  • Load javascript in app engine

    - by user624392
    I got so confused loading javascript in app engine. I am using django template. In my base html file. First I can't load my downloaded jquery from local say d:/jquery.js like <script src="d:\jquery.js" type="text/javascript" ></script></head>, This line is in my base html file. It works when I load jquery from remote. Like <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"type="text/javascript" ></script></head> I dont know why. Second, I can't load my own-created javascript to my html file, say I create a javascript like layout. Js and I try to load it like this in my child html file, which, by the way, inherits from the base html. <body><script src="layout.js" type="text/javascript"></script></body>, And it doesn't work at all, the only way it works I have tried is that I put the actual javascript in the body of my base html file. Like <body><script> $(document).ready( $("#yes"). Click(function() { $("#no"). Hide("slow"); })); </script> I dont know why either... Any help?

  • Single-Page Web Apps: Client-side datastores & server persistence

    - by fig-gnuton
    How should client-side datastores & persistence be handled in a single-page web application? Global vars vs. DI/IoC: Should datastores be assigned to global variables so any part of the application can access them? Or should they be dependency injected where required? Server persistence: Assuming a datastore's data needn't always be persisted to the server immediately, should the datastore itself handle persistence? If not, then what class should handle persistence and how should the persistence class fit into the client-side architecture overall? Is the datastore considered the model in MVC, or is it something else since it just stores raw data?

  • echo php javascript alert?

    - by Anaes Arias
    How can I echo this javascript if the php error messages is called? I have an error message setting that when a user misses his username or password it triggers an error message. The php error message is called by a php code. Here is the code: <?php echo showmessage($msg) ?> I have an alert message in javascript that when called it will make a javascript css pop up alert box. IF the javascript code is present it will show the alert box right away after reload. Here is code: <script type="text/javascript"> $(document).ready(function () { jqxAlert.alert('Alert Message'); }) </script> How can I incorporate so that when the php echo message comes up it will trigger the javscript alert message. I was trying an if in php, so something like this code: if ( showmessage($msg) ) { <script type="text/javascript"> $(document).ready(function () { jqxAlert.alert('Alert Message'); }) </script> } How can I echo my javascript message on the php call?

  • Eclipse > Javascript > Code highlighting not working with Object Notation

    - by Redsandro
    I am using Eclipse Helios with PDT, and when I am editing JavaScript files with the default JavaScript Editor (JSDT), code highlighting (Mark Occurrences) is not working for half of the code, for example JSON-style (or Object Literal if you will) declarations. Little example: Foo = {}; Foo.Bar = Foo.Bar || {}; Foo.Bar = { bar: function(str) { alert(str) }, baz: function(str) { this.bar(str); // This bar *is* highlighted though } }; Foo.Bar.baz('text'); No Bar, bar or baz is highlighted. For now, I humbly edit the JavaScript part of projects in Notepad++ because it just highlights every occurrence of whatever is currently selected. Is there a common practice for Eclipse JavaScript developers to get code highlighting work correctly, using the popular Object Literal notation? An option or update I missed? -update- I have found that code highlighting depends on the code being properly outlined. Altough commonly used, Object Literal outlining still seems rare in javascript editors. the Spket Javascript Editor does partial Object Literal outlining, and the Aptana Javascript Editor does full Object Literal outlining. But both loses other important functionality. A quest for the editor with the least loss of functionality is currently in progress in this question.

  • loading remote page into DOM with javascript

    - by scoobydoo
    I am trying to write a web widget which will allow users to display customized information (from my website) in their own web page. The mechanism I want to use (for creating the web widget) is javascript. So basically, I want to be able to write some javascript code like this (this is what the end user copies into their HTML page, to get my widget displayed in their page) <script type="text/javascript"> /* javascript here to fetch page from remote url and insert into DOM */ </script> I have two questions: how do I write a javascript code to fetch the page from the remote url? Ideally this will be PLAIN javascript (i.e. not using jQuery etc - since I dont want to force the user to get third party scripts jQuery which may conflict with other scripts on their page etc) The page I am fetching contains inline javascript, which gets executed in an body.onLoad event, as well as other functions which are used in response to user actions - my questions are: i). will the body.onLoad event be triggered for the retrieved document?. ii). If the retrieved page is dumped directly into the DOM, then the document will contain two <body> sections, which is no longer valid (X)HTML - however, I need the body.onLoad event to be triggered for the page to be setup correctly, and I also need the other functions in the retrieved page, for the retrieved page to be able to respond to the user interaction. Any suggestions/tips on how I can solve these problems?

  • Methods for breaking up content client-side into multiple "pages"

    - by Tom Genoni
    I have a long HTML text-only article formatted with paragraph tags. What I'd like to do is break this content into N number of divs so that I can create individual pages. So, for instance, on an iPad/iPhone, instead of reading one long page the user could swipe right/left to navigate to pages. My initial javascript attempts have been somewhat convoluted: creating an array of the text, measuring line-heights, device window heights, adding closing/opening paragraph tags and the end/beginning of pages. Thoughts on a good way to approach this? I will not have access to server-side processing, this has to be a client-side solution.

  • A server-side language to Learn

    - by Roth
    I'm a graphic designer, with experience in print design. In fact, I'm working on digital prepress since 4 years ago. I'm doing a course on web design right now, although I have been studying it on my own for a while, online. So, my question is, what kind of server-side language do I need to learn? I'm feel comfortable with HTML, CSS, and Javascript, even with preprocessors like SASS and LESS, but server-side scripting becomes a nightmare to me. So, what kind of language is necessary to learn? Any book or resource to that specific language? Thanks a lot for your answers.

  • Server 2003 Terminal Services Printers not redirecting, no sessions created.

    - by mikerdz
    Ok, odd scenario on a Windows Server 2003 Server Standard running as Terminal Server. Friday, installed 2 new Windows 7 machines to replace older XP machines. After adding these machines and their local printers, none of the otehr 16 Windows 7 machines can redirect printing to the server. I have checked Global Policy on domain controller, nothing is being blocked. In Terminal Services Manager, the client settings are set to User Client Settings. On RDP client, port redirection is enabled. I have tried disabling the Use Client Settings option and manually selected the options for print redirection and default printer connection, but still does not work. After some reaserching, I found this MS article: http://support.microsoft.com/kb/2492632 I went ahead and added the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\fEnablePrintRDR DWORD that the article references and set it to "1" to enable the option. I restarted the server, but still would not print. I am getting quite desperate with this issue because nothing seems to have changed when installing the two new clients and printers. I uninstalled the print drivers for the printers from the server. I have even gone as far as connecting each of the printers manually via UPD (\computername\printer) but even thought it works, it prints awfully slow. Please help!!!!

  • How to configure a trusted connection between IIS 7 and SQL Server 2005?

    - by user1180652
    How do configure a trusted connection between IIS 7 and SQL Server 2005? My webapp was working fine with Windows Authentication enabled in IIS. Now, in order to solve a problem, we need to use a trusted connection. Unfortunately, enabling the trusted connection in the web.config broke the webapp. Oddly enough, when I run this application with trusted connection from my local dev machine (using the Cassini web server) IIS (Windows Server 2008) is running on one machine. The database (SQL Server 2005 but could migrate to 2008) is running on another machine. We are on a Windows domain running AD. All traffic is within our own firewall - no public access. Beyond that, I can't provide much info but I can find it. We're very "compartmentalized" (we have server people, security people, oracle people, SQL Server people, etc.) Thanks! Update 02/14/2012 0902: The webapp is now functional (app no longer broken) but the main issue is still unresolved. Now I have the app's application pool running as a domain account with permissions on the SQL Server box and IIS box. We were using this account to run the application but, and here's the problem, we need to log the real user name that made a change. When using the service account, the name of that service account appeared in the audit tables, making the auditing quite useless. So, not I'm at least running again. The connection string in the web.config is using "Trusted_Connection=True", the appPool is using a domain account with access to both boxes, BUT when I make a change (logged in as me) the name of the service account (appPool identity) is still logged in the audit tables. I also manually granted full permissions to the service account on the webapp folder. What do I need to do in order to log my name, not the service account, in the audit tables? Everything I'm reading says I need to establish a trusted connection between the two servers.

  • SQL SERVER – Weekly Series – Memory Lane – #032

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 Complete Series of Database Coding Standards and Guidelines SQL SERVER Database Coding Standards and Guidelines – Introduction SQL SERVER – Database Coding Standards and Guidelines – Part 1 SQL SERVER – Database Coding Standards and Guidelines – Part 2 SQL SERVER Database Coding Standards and Guidelines Complete List Download Explanation and Example – SELF JOIN When all of the data you require is contained within a single table, but data needed to extract is related to each other in the table itself. Examples of this type of data relate to Employee information, where the table may have both an Employee’s ID number for each record and also a field that displays the ID number of an Employee’s supervisor or manager. To retrieve the data tables are required to relate/join to itself. Insert Multiple Records Using One Insert Statement – Use of UNION ALL This is very interesting question I have received from new developer. How can I insert multiple values in table using only one insert? Now this is interesting question. When there are multiple records are to be inserted in the table following is the common way using T-SQL. Function to Display Current Week Date and Day – Weekly Calendar Straight blog post with script to find current week date and day based on the parameters passed in the function.  2008 In my beginning years, I have almost same confusion as many of the developer had in their earlier years. Here are two of the interesting question which I have attempted to answer in my early year. Even if you are experienced developer may be you will still like to read following two questions: Order Of Column In Index Order of Conditions in WHERE Clauses Example of DISTINCT in Aggregate Functions Have you ever used DISTINCT with the Aggregation Function? Here is a simple example about how users can do it. Create a Comma Delimited List Using SELECT Clause From Table Column Straight to script example where I explained how to do something easy and quickly. Compound Assignment Operators SQL SERVER 2008 has introduced new concept of Compound Assignment Operators. Compound Assignment Operators are available in many other programming languages for quite some time. Compound Assignment Operators is operator where variables are operated upon and assigned on the same line. PIVOT and UNPIVOT Table Examples Here is a very interesting question – the answer to the question can be YES or NO both. “If we PIVOT any table and UNPIVOT that table do we get our original table?” Read the blog post to get the explanation of the question above. 2009 What is Interim Table – Simple Definition of Interim Table The interim table is a table that is generated by joining two tables and not the final result table. In other words, when two tables are joined they create an interim table as resultset but the resultset is not final yet. It may be possible that more tables are about to join on the interim table, and more operations are still to be applied on that table (e.g. Order By, Having etc). Besides, it may be possible that there is no interim table; sometimes final table is what is generated when the query is run. 2010 Stored Procedure and Transactions If Stored Procedure is transactional then, it should roll back complete transactions when it encounters any errors. Well, that does not happen in this case, which proves that Stored Procedure does not only provide just the transactional feature to a batch of T-SQL. Generate Database Script for SQL Azure When talking about SQL Azure the most common complaint I hear is that the script generated from stand-along SQL Server database is not compatible with SQL Azure. This was true for some time for sure but not any more. If you have SQL Server 2008 R2 installed you can follow the guideline below to generate a script which is compatible with SQL Azure. Convert IN to EXISTS – Performance Talk It is NOT necessary that every time when IN is replaced by EXISTS it gives better performance. However, in our case listed above it does for sure give better performance. You can read about this subject in the associated blog post. Subquery or Join – Various Options – SQL Server Engine Knows the Best Every single time whenever there is a performance tuning exercise, I hear the conversation from developer where some prefer subquery and some prefer join. In this two part blog post, I explain the same in the detail with examples. Part 1 | Part 2 Merge Operations – Insert, Update, Delete in Single Execution MERGE is a new feature that provides an efficient way to do multiple DML operations. In earlier versions of SQL Server, we had to write separate statements to INSERT, UPDATE, or DELETE data based on certain conditions; however, at present, by using the MERGE statement, we can include the logic of such data changes in one statement that even checks when the data is matched and then just update it, and similarly, when the data is unmatched, it is inserted. 2011 Puzzle – Statistics are not updated but are Created Once Here is the quick scenario about my setup. Create Table Insert 1000 Records Check the Statistics Now insert 10 times more 10,000 indexes Check the Statistics – it will be NOT updated – WHY? Question to You – When to use Function and When to use Stored Procedure Personally, I believe that they are both different things - they cannot be compared. I can say, it will be like comparing apples and oranges. Each has its own unique use. However, they can be used interchangeably at many times and in real life (i.e., production environment). I have personally seen both of these being used interchangeably many times. This is the precise reason for asking this question. 2012 In year 2012 I had two interesting series ran on the blog. If there is no fun in learning, the learning becomes a burden. For the same reason, I had decided to build a three part quiz around SEQUENCE. The quiz was to identify the next value of the sequence. I encourage all of you to take part in this fun quiz. Guess the Next Value – Puzzle 1 Guess the Next Value – Puzzle 2 Guess the Next Value – Puzzle 3 Guess the Next Value – Puzzle 4 Simple Example to Configure Resource Governor – Introduction to Resource Governor Resource Governor is a feature which can manage SQL Server Workload and System Resource Consumption. We can limit the amount of CPU and memory consumption by limiting /governing /throttling on the SQL Server. If there are different workloads running on SQL Server and each of the workload needs different resources or when workloads are competing for resources with each other and affecting the performance of the whole server resource governor is a very important task. Tricks to Replace SELECT * with Column Names – SQL in Sixty Seconds #017 – Video  Retrieves unnecessary columns and increases network traffic When a new columns are added views needs to be refreshed manually Leads to usage of sub-optimal execution plan Uses clustered index in most of the cases instead of using optimal index It is difficult to debug SQL SERVER – Load Generator – Free Tool From CodePlex The best part of this SQL Server Load Generator is that users can run multiple simultaneous queries again SQL Server using different login account and different application name. The interface of the tool is extremely easy to use and very intuitive as well. A Puzzle – Swap Value of Column Without Case Statement Let us assume there is a single column in the table called Gender. The challenge is to write a single update statement which will flip or swap the value in the column. For example if the value in the gender column is ‘male’ swap it with ‘female’ and if the value is ‘female’ swap it with ‘male’.

  • SQL SERVER – Weekly Series – Memory Lane – #053 – Final Post in Series

    - by Pinal Dave
    It has been a fantastic journey to write memory lane series for an entire year. This series gave me the opportunity to go back and see what I have contributed to this blog throughout the last 7 years. This was indeed fantastic series as this provided me the opportunity to witness how technology has grown throughout the year and how I have progressed in my career while writing this blog post. This series was indeed fantastic experience readers as many joined during the last few years and were not sure what they have missed in recent years. Let us continue with the final episode of the Memory Lane Series. Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it.

Disable All Triggers on a Database – Disable All Triggers on All Servers Question : How to disable all the triggers for a database? Additionally, how to disable all the triggers for all servers? For answer execute the script in the blog post. Importance of Master Database for SQL Server Startup I have received following questions many times. I will list all the questions here and answer them together. What is the purpose of Master database? Should our backup Master database? Which database is must have database for SQL Server for startup? Which are the default system database created when SQL Server 2005 is installed for the first time? What happens if Master database is corrupted? Answers to all of the questions are very much related. 2008 DECLARE Multiple Variables in One Statement SQL Server is a great product and it has many features which are very unique to SQL Server. Regarding feature of SQL Server where multiple variable can be declared in one statement, it is absolutely possible to do. 2009 How to Enable Index – How to Disable Index – Incorrect syntax near ‘ENABLE’ Many times I have seen that the index is disabled when there is a large update operation on the table. Bulk insert of very large file updates in any table using SSIS is usually preceded by disabling the index and followed by enabling the index. I have seen many developers running the following query to disable the index. 2010 List of all the Views from Database Many emails I received suggesting that they have hundreds of the view and now have no clue what is going on and how many of them have indexes and how many does not have an index. Some even asked me if there is any way they can get a list of the views with the property of Index along with it. Here is the quick script which does exactly the same. You can also include many other columns from the same view. Minimum Maximum Memory – Server Memory Options I was recently reading about SQL Server Memory Options over here. While reading this one line really caught my attention is minimum value allowed for maximum memory options. The default setting for min server memory is 0, and the default setting for max server memory is 2147483647. The minimum amount of memory you can specify for max server memory is 16 megabytes (MB). 2011 Fundamentals of Columnstore Index There are two kinds of storage in a database. Row Store and Column Store. Row store does exactly as the name suggests – stores rows of data on a page – and column store stores all the data in a column on the same page. These columns are much easier to search – instead of a query searching all the data in an entire row whether the data are relevant or not, column store queries need only to search a much lesser number of the columns. How to Ignore Columnstore Index Usage in Query In summary the question in simple words “How can we ignore using the column store index in selective queries?” Very interesting question – you can use I can understand there may be the cases when the column store index is not ideal and needs to be ignored the same. You can use the query hint IGNORE_NONCLUSTERED_COLUMNSTORE_INDEX to ignore the column store index. The SQL Server Engine will use any other index which is best after ignoring the column store index. 2012 Storing Variable Values in Temporary Array or Temporary List SQL Server does not support arrays or a dynamic length storage mechanism like list. Absolutely there are some clever workarounds and few extra-ordinary solutions but everybody can;t come up with such solution. Additionally, sometime the requirements are very simple that doing extraordinary coding is not required. Here is the simple case. Move Database Files MDF and LDF to Another Location It is not common to keep the Database on the same location where OS is installed. Usually Database files are in SAN, Separate Disk Array or on SSDs. This is done usually for performance reason and manageability perspective. Now the challenges comes up when database which was installed at not preferred default location and needs to move to a different location. Here is the quick tutorial how you can do it. UNION ALL and ORDER BY – How to Order Table Separately While Using UNION ALL If your requirement is such that you want your top and bottom query of the UNION resultset independently sorted but in the same result set you can add an additional static column and order by that column. Let us re-create the same scenario.

  • How to reference a sql server with a slash (\) in its name?

    - by Bill Paetzke
    Givens: One SQL Server is named: DevServerA Another is named: DevServerB\2K5 Problem: From DevServerA, how can I write a query that references DevServerB\2K5? I tried a sample, dummy query (running it from DevServerA): SELECT TOP 1 * FROM DevServerB\2K5.master.sys.tables And I get the error: Msg 102, Level 15, State 1, Line 2 Incorrect syntax near '\.'. However, I know my syntax is almost correct, since the other way around works (running this query from DevServerB\2K5): SELECT TOP 1 * FROM DevServerA.master.sys.tables Please help me figure out how to reference DevServerB\2K5 from DevServerA. Thanks.

  • SQL Server: How to remove empty lines in SSMS?

    - by atricapilla
    I have many .sql files with lots of empty lines e.g. WITH cteTotalSales (SalesPersonID, NetSales) AS ( SELECT SalesPersonID, ROUND(SUM(SubTotal), 2) FROM Sales.SalesOrderHeader WHERE SalesPersonID IS NOT NULL GROUP BY SalesPersonID ) SELECT sp.FirstName + ' ' + sp.LastName AS FullName, sp.City + ', ' + StateProvinceName AS Location, ts.NetSales FROM Sales.vSalesPerson AS sp INNER JOIN cteTotalSales AS ts ON sp.BusinessEntityID = ts.SalesPersonID ORDER BY ts.NetSales DESC Is ther a way to remove these empty lines in SQL Server Management Studio? This is what I would like to have: WITH cteTotalSales (SalesPersonID, NetSales) AS ( SELECT SalesPersonID, ROUND(SUM(SubTotal), 2) FROM Sales.SalesOrderHeader WHERE SalesPersonID IS NOT NULL GROUP BY SalesPersonID ) SELECT sp.FirstName + ' ' + sp.LastName AS FullName, sp.City + ', ' + StateProvinceName AS Location, ts.NetSales FROM Sales.vSalesPerson AS sp INNER JOIN cteTotalSales AS ts ON sp.BusinessEntityID = ts.SalesPersonID ORDER BY ts.NetSales DESC

  • SQL SERVER – Fix : Error : 3117 : The log or differential backup cannot be restored because no files

    - by pinaldave
    I received the following email from one of my readers. Dear Pinal, I am new to SQL Server and our regular DBA is on vacation. Our production database had some problem and I have just restored full database backup to production server. When I try to apply log back I am getting following error. I am sure, this is valid log backup file. Screenshot is attached. [Few other details regarding server/ip address removed] Msg 3117, Level 16, State 1, Line 1 The log or differential backup cannot be restored because no files are ready to roll forward. Msg 3013, Level 16, State 1, Line 1 RESTORE LOG is terminating abnormally. Screenshot attached. [Removed as it contained live IP address] Please help immediately. Well I have answered this question in my earlier post, 2 years ago, over here SQL SERVER – Fix : Error : Msg 3117, Level 16, State 4 The log or differential backup cannot be restored because no files are ready to rollforward. However, I will try to explain it a little more this time. For SQL Server database to be used it should in online state. There are multiple states of SQL Server Database. ONLINE (Available – online for data) OFFLINE RESTORING RECOVERING RECOVERY PENDING SUSPECT EMERGENCY (Limited Availability) If the database is online, it means it is active and in operational mode. It will not make sense to apply further log from backup if the operations have continued on this database. The common practice during the backup restore process is to specify the keyword RECOVERY when the database is restored. When RECOVERY keyword is specified, the SQL Server brings back the database online and will not accept any further log backups. However, if you want to restore more than one backup files, i.e. after restoring the full back up if you want to apply further differential or log backup you cannot do that when database is online and already active. You need to have your database in the state where it can further accept the backup data and not the online data request. If the SQL Server is online and also accepts database backup file, then there can be data inconsistency. This is the reason that when there are more than one database backup files to be restored, one has to restore the database with NO RECOVERY keyword in the RESTORE operation. I suggest you all to read one more post written by me earlier. In this post, I explained the time line with image and graphic SQL SERVER – Backup Timeline and Understanding of Database Restore Process in Full Recovery Model. Sample Code for reference: RESTORE DATABASE AdventureWorks FROM DISK = 'C:\AdventureWorksFull.bak' WITH NORECOVERY; RESTORE DATABASE AdventureWorks FROM DISK = 'C:\AdventureWorksDiff.bak' WITH RECOVERY; In this post, I am not trying to cover complete backup and recovery. I am just attempting to address one type of error and its resolution. Please test these scenarios on the development server. Playing with live database backup and recovery is always very crucial and needs to be properly planned. Leave a comment here if you need help with this subject.

  • SQL Server – SafePeak “Logon Trigger” Feature for Managing Data Access

    - by pinaldave
    Lately I received an interesting question about the abilities of SafePeak for SQL Server acceleration software: Q: “I would like to use SafePeak to make my CRM application faster. It is an application we bought from some vendor, after a while it became slow and we can’t reprogram it. SafePeak automated caching sounds like an easy and good solution for us. But, in my application there are many servers and different other applications services that address its main database, and some even change data, and I feel that there is a chance that some servers that during the connection process we may miss some. Is there a way to ensure that SafePeak will be aware of all connections to the SQL Server, so its cache will remain intact?” Interesting question, as I remember that SafePeak (http://www.safepeak.com/Product/SafePeak-Overview) likes that all traffic to the database will go thru it. I decided to check out the features of SafePeak latest version (2.1) and seek for an answer there. A: Indeed I found SafePeak has a feature they call “Logon Trigger” and is designed for that purpose. It is located in the user interface, under: Settings -> SQL instances management  ->  [your instance]  ->  [Logon Trigger] tab. From here you activate / deactivate it and control a white-list of enabled server IPs and Login names that SafePeak will ignore them. Click to Enlarge After activation of the “logon trigger” Safepeak server is notified by the SQL Server itself on each new opened connection. Safepeak monitors those connections and decides if there is something to do with them or not. On a typical installation SafePeak likes all application and users connections to go via SafePeak – this way it knows about data and schema updates immediately (real time). With activation of the safepeak “logon trigger”  a special CLR trigger is deployed on the SQL server and notifies Safepeak on any connection that has not arrived via SafePeak. In such cases Safepeak can act to clear and lock the cache or to ignore it. This feature enables to make sure SafePeak will be aware of all connections so SafePeak cache will maintain exactly correct all times. So even if a user, like a DBA will connect to the SQL Server not via SafePeak, SafePeak will know about it and take actions. The notification does not impact the work of that connection, the user or application still continue to do whatever they planned to do. Note: I found that activation of logon trigger in SafePeak requires that SafePeak SQL login will have the next permissions: 1) CONTROL SERVER; 2) VIEW SERVER STATE; 3) And the SQL Server instance is CLR enabled; Seeing SafePeak in action, I can say SafePeak brings fantastic resource for those who seek to get performance for SQL Server critical apps. SafePeak promises to accelerate SQL Server applications in just several hours of installation, automatic learning and some optimization configuration (no code changes!!!). If better application and database performance means better business to you – I suggest you to download and try SafePeak. The solution of SafePeak is indeed unique, and the questions I receive are very interesting. Have any more questions on SafePeak? Please leave your question as a comment and I will try to get an answer for you.

Make sure that you have configured the firewall on the server instance of SQL Server to open ports for SQL Server and the SQL Server Browser port (UDP 1434). Make sure that the SQL Server Browser service is started on the server. in addition to theese i have disabled the firewall completely and tried other ports nothing works the same credentials work on the server but not on the client. this is the exact error message A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
