• SQL SERVER – Color Coding SQL Server Management Studio Status Bar – SQL in Sixty Seconds #023 – Video

  - by pinaldave

  I often see developers executing the unplanned code on production server when they actually want to execute on the development server. Developers and DBAs get confused because when they use SQL Server Management Studio (SSMS) they forget to pay attention to the server they are connecting. It is very easy to fix this problem. You can select different color for a different server. Once you have different color for different server in the status bar, it will be easier for developer easily notice the server against which they are about to execute the script. Personally when I work on SQL Server development, here is the color code, which I follow. I keep Green for my development server, blue for my staging server and red for my production server. Honestly color coding does not signify much but different color for different server is the key here.

• SQL SERVER – Resolving SQL Server Connection Errors – SQL in Sixty Seconds #030 – Video

  - by pinaldave

  One of the most famous errors related to SQL Server is about connecting to SQL Server itself. Here is how it goes, most of the time developers have worked with SQL Server and knows pretty much every error which they face during development language. However, hardly they install fresh SQL Server. As the installation of the SQL Server is a rare occasion unless you are DBA who is responsible for such an instance – the error faced during installations are pretty rare as well. I have earlier written an article about this which describes how to resolve the errors which are related to SQL Server connection. Even though the step by step directions are pretty simple there are many first time IT Professional who are not able to figure out how to resolve this error. I have quickly built a video which is covering most of the solutions related to resolving the connection error. In the Fix SQL Server Connection Error article following workarounds are described: SQL Server Services TCP/IP Settings Firewall Settings Enable Remote Connection Browser Services Firewall exception of sqlbrowser.exe Recreating Alias Related Tips in SQL in Sixty Seconds: SQL SERVER – FIX : ERROR : (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server) (Microsoft SQL Server, Error: ) SQL SERVER – Could not connect to TCP error code 10061: No connection could be made because the target machine actively refused it SQL SERVER – Connecting to Server Using Windows Authentication by SQLCMD SQL SERVER – Fix : Error: 15372 Failed to generate a ser instance od SQL Server due to a failure in starting the process for the user instance.

• SQL SERVER – Tricks to Comment T-SQL in SSMS – SQL in Sixty Seconds #019 – Video

  - by pinaldave

  Code commeting is the one of the most common tasks developers perform. There are two major reasons why developer comment code. 1) During Debug 2) Documenting the code. While debugging the T-SQL code I have often seen developers struggling to comment code.  They spend (or waste) more time in commenting and uncommenting  than doing actual debugging of the procedure.  When I see developer struggling to comment the code I feel little uncomfortable as commenting should be a very easy task over. Today we will see three quick method to comment T-SQL code in Query Editor. There are three different method to comment and uncomment statements in SQL Server Management Studio Using Keyboard Shortcuts Using Tool Bar Using Menu Bar Method 1: Using Keyboard Shortcuts Commenting the statement – CTRL+K, CTRL+C Commenting the statement – CTRL+K, CTRL+U Method 2: Using Tool Bar Using Tool bar buttons. (See Video) Method 3: Using Menu Bar Commenting the statement – Menu Bar >> Edit >> Advanced >> Click on Comment Selection. Unommenting the statement – Menu Bar >> Edit >> Advanced >> Click on Uncomment Selection.

• SQLAuthority News – Pinal Dave: Blogger, MVP and now Interviewee by Michael J Swart

  - by pinaldave

  Michael J. Swart is a very unique person. I have often exchanged emails with him and also used a couple of his scripts in my presentations (with his permission). Every time I conduct spatial database presentation, I always start with his script where he has drawn the wonderful image of Botticelli’s Birth of Venus. I often think he is more of a creative artist than IT professional. However, if you read his blog posts and articles, they are top notch and each article is as creative as his caricatures. He is wonderful, inspiring, creative and most importantly, very humble. He recently took my interview and asked me some very interesting question. To answer his question, I had to share some of the interesting aspects of my life which I have had never shared in any interview before. He made me share the following interesting facts. Pinal Dave Caricatures Read my Interview Here are a few questions that I have answered at his blog: How I met my wife? Best moments of my life? How to pronounce my last name? Who inspired me? English as a Third Language. I am also thankful to Michael for drawing my caricature. I really liked it and I am very glad that he took time to do so.

• SQL SERVER – Delay Command in SQL Server – SQL in Sixty Seconds #055

  - by Pinal Dave

  Have you ever needed WAIT or DELAY function in SQL Server?  Well, I personally have never needed it but I see lots of people asking for the same. It seems the need of the function is when developers are working with asynchronous applications or programs. When they are working with an application where user have to wait for a while for another application to complete the processing. If you are programming language developer, it is very easy for you to make the application wait for command however, in SQL I personally have rarely used this feature.  However, I have seen lots of developers asking for this feature in SQL Server, hence I have decided to build this quick video on the same subject. We can use WAITFOR DELAY ‘timepart‘ to create a SQL Statement to wait. Let us see the same concept in following SQL in Sixty Seconds Video: Related Tips in SQL in Sixty Seconds: Delay Function – WAITFOR clause – Delay Execution of Commands What would you like to see in the next SQL in Sixty Seconds video?

• SQL SERVER – A Puzzle – Illusion – Confusion – April Fools’ Day

  - by pinaldave

  Today is April 1st and just like every other year, I like to bring something interesting and light for the day. Atleast there should be days in every one’s life when they should feel easy. Here is a quick puzzle for you and I believe it will make you feel extremely smart if you can figure out the result behind the same. Run following in SQL Server Management Studio and observe the output: SELECT 30.0/(-2.0)/5.0; SELECT 30.0/-2.0/5.0; Here are few questions for you: 1) What will be the result of above two queries? 2) Why? If you think you can figure out the result without executing them – I encourage you to execute BOTH of them in SSMS and see if they give you same result or different result. Well, now I am waiting for your answer here – why? I often post similar things on my facebook page http://facebook.com/SQLAuth – you are welcome to play with me there.

• SQL SERVER – CTRL+SHIFT+] Shortcut to Select Code Between Two Parenthesis

  - by pinaldave

  Every weekend brings creative ideas and accidents brings best unknown secrets in front of us. Just a day while working with complex SQL Server code in SSMS I came across very interesting shortcut which I have never used before and instantly fell in love with it. It is totally possible that you are familiar with this but for me it was the first time and I was surprised that I did know know this short cut so far. Shortcut key is CTRL+SHIFT+]. This key can be very useful when dealing with multiple subqueries, CTE or query with multiple parentheses. When exercised this shortcut key it selects T-SQL code between two parentheses. Let us see the examples to understand the same. In each of the examples I have put the cursor at the position displayed and pressed CTRL+SHIFT+] and it has selected the code between two corresponding parentheses. Cursor position 1 Cursor position 2 Cursor position 3 If you are a developer and have to code with complex queries, you will totally appreciate that this feature can save so much of the time for development. I often remember my experience as a developer when I have lost a lot of hours to just balance parentheses. As I said yesterday I found this shortcut accidently. How many of you were aware of this feature? Is there any other useful feature you would like to share with us? Please leave a comment and if I have not covered it earlier, I will share it due credit on this blog.

• SQL SERVER – sp_describe_first_result_set New System Stored Procedure in SQL Server 2012

  - by pinaldave

  I might have said this earlier many times but I will say it again – SQL Server never stops to amaze me. Here is the example of it sp_describe_first_result_set. I stumbled upon it when I was looking for something else on BOL. This new system stored procedure did attract me to experiment with it. This SP does exactly what its names suggests – describes the first result set. Let us see very simple example of the same. Please note that this will work on only SQL Server 2012. EXEC sp_describe_first_result_set N'SELECT * FROM AdventureWorks.Sales.SalesOrderDetail', NULL, 1 GO Here is the partial resultset. Now let us take this simple example to next level and learn one more interesting detail about this function. First I will be creating a view and then we will use the same procedure over the view. USE AdventureWorks GO CREATE VIEW dbo.MyView AS SELECT [SalesOrderID] soi_v ,[SalesOrderDetailID] sodi_v ,[CarrierTrackingNumber] stn_v FROM [Sales].[SalesOrderDetail] GO Now let us execute above stored procedure with various options. You can notice I am changing the very last parameter which I am passing to the stored procedure.This option is known as for browse_information_mode. EXEC sp_describe_first_result_set N'SELECT soi_v soi, sodi_v sodi, stn_v stn FROM MyView', NULL, 0; GO EXEC sp_describe_first_result_set N'SELECT soi_v soi, sodi_v sodi, stn_v stn FROM MyView', NULL, 1; GO EXEC sp_describe_first_result_set N'SELECT soi_v soi, sodi_v sodi, stn_v stn FROM MyView', NULL, 2; GO Here is result of all the three queries together in single image for easier understanding regarding their difference. You can see that when BrowseMode is set to 1 the resultset describes the details of the original source database, schema as well source table. When BrowseMode is set to 2 the resulset describes the details of the view as the source database. I found it really really interesting that there exists system stored procedure which now describes the resultset of the output.

• SQL SERVER – Identify Most Resource Intensive Queries – SQL in Sixty Seconds #028 – Video

  - by pinaldave

  During performance tuning conversation the very first question people often ask is what are the queries offending the server or in another word let us identify the queries which are the most resource intensive. The resources are often described as either Memory, CPU or IO. When we talk about the queries the same is applicable for them as well. The query which is doing lots of reads or writes are for sure resource intensive as well query which are taking maximum CPU time. Performance tuning is a very deep subject and we all have our own preference regarding what should be the first step to tuning and what should be looked with the salt of grain. Though there is no denying that a query which uses more resources than what it should be using for sure require tuning. There are many ways to do identify query using intense resources (e.g. Extended events etc) but in this one we will go by simple DMV. There is a small gotcha we all have to remember about usage of DMV is that it only brings back results from existing cache. So if you have a query which is very resource intensive but is not cached or if you have explicitly removed the query from the cache it will be not part of the result returned by this DMV. It is quite possible that a query is aged and removed from the cache if your cache is not huge. If your cache is large you may want to be careful in running this query during business hours as this query itself can be resource intensive.

• SQL Server – Learning SQL Server Performance: Indexing Basics – Interview of Vinod Kumar by Pinal Dave

  - by pinaldave

  Recently I just wrote a blog post on about Learning SQL Server Performance: Indexing Basics and I received lots of request that if we can share some insight into the course. Every single time when Performance is discussed, Indexes are mentioned along with it. In recent times, data and application complexity is continuously growing.  The demand for faster query response, performance, and scalability by organizations is increasing and developers and DBAs need to now write efficient code to achieve this. When we developed the course – we made sure that this course remains practical and demo heavy instead of just theories on this subject. Vinod Kumar and myself we often thought about this and realized that practical understanding of the indexes is very important. One can not master every single aspects of the index. However there are some minimum expertise one should gain if performance is one of the concern. Here is 200 seconds interview of Vinod Kumar I took right after completing the course.

• SQL SERVER – Fix – Agent Starting Error 15281 – SQL Server blocked access to procedure ‘dbo.sp_get_sqlagent_properties’ of component ‘Agent XPs’ because this component is turned off as part of the security configuration for this server

  - by Pinal Dave

  SQL Server Agent fails to start because of the error 15281 is a very common error. When you start to restart SQL Agent sometimes it will give following error. SQL Server blocked access to procedure ‘dbo.sp_get_sqlagent_properties’ of component ‘Agent XPs’ because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of ‘Agent XPs’ by using sp_configure. For more information about enabling ‘Agent XPs’, search for ‘Agent XPs’ in SQL Server Books Online. (Microsoft SQL Server, Error: 15281) To resolve this error, following script has to be executed on the server. sp_configure 'show advanced options', 1; GO RECONFIGURE; GO sp_configure 'Agent XPs', 1; GO RECONFIGURE GO When you run above script, it will give a very similar output as following on the screen. Now, if you try to restart SQL Agent it will just work fine. That’s it! Sometimes there is a simpler solution to complicated error.

• SQL SERVER – 2008 – Missing Index Script – Download

  - by pinaldave

  Download Missing Index Script with Unused Index Script Performance Tuning is quite interesting and Index plays a vital role in it. A proper index can improve the performance and a bad index can hamper the performance. Here is the script from my script bank which I use to identify missing indexes on any database. Please note, if you should not create all the missing indexes this script suggest. This is just for guidance. You should not create more than 5-10 indexes per table. Additionally, this script sometime does not give accurate information so use your common sense. Any way, the scripts is good starting point. You should pay attention to Avg_Estimated_Impact when you are going to create index. The index creation script is also provided in the last column.

• SQL SERVER – Puzzle to Win Print Book – Write T-SQL Self Join Without Using FIRST _VALUE and LAST_VALUE

  - by pinaldave

  Last week we asked a puzzle SQL SERVER – Puzzle to Win Print Book – Functions FIRST_VALUE and LAST_VALUE with OVER clause and ORDER BY . This puzzle got very interesting participation. The details of the winner is listed here. In this puzzle we received two very important feedback. This puzzle cleared the concepts of First_Value and Last_Value to the participants. As this was based on SQL Server 2012 many could not participate it as they have yet not installed SQL Server 2012. I really appreciate the feedback of user and decided to come up something as fun and helps learn new feature of SQL Server 2012. Please read yesterday’s blog post SQL SERVER – Introduction to LEAD and LAG – Analytic Functions Introduced in SQL Server 2012 before continuing this puzzle as it is based on yesterday’s post. Yesterday I ran following query which uses functions LEAD and LAG. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, FIRST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID) FstValue, LAST_VALUE(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID) LstValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO The above query will give us the following result: Puzzle: Now use T-SQL Self Join where same table is joined to itself and get the same result without using LEAD or LAG functions.

• SQLAuthority News – Download Whitepaper – A Case Study on “Hekaton” against RPM – SQL Server 2014 CTP1

  - by Pinal Dave

  In this new world of social media, apps and mobile devices, we are all now getting impatient. Automatic updates have spoiled few of our habits. When a new feature is released everybody wants to immediately adopt the feature and start using it. Though this is true in the world of apps and smart phones, but it is still not possible in the developer’s world. When new features are around, before we start using it, we need to spend quite a lots of time to understand it and test it. Once we are sold on the feature we refer the feature to our manager and eventually the entire organization makes decisions on upgrading to use the new feature. Similarly, when the new feature of In-Memory OLTP was announced, pretty much every SQL Server DBA wanted to implement that on their server. Through the implementation of the feature is not hard, it is not that easy as well. One has to do proper research about their own environment and workload before implementing this feature. Microsoft has recently released a Case Study on In-Memory OLTP feature. Here is the abstract from the white paper itself. I/O latch can cause session delays that impact application performance. This white paper describes the procedures and common I/O latch issues when migrating to Hekaton in SQL Server 2014. It also includes challenges that occurred during the migration and the performance analysis at different stages.  If you are going to implement In-Memory OLTP database, this is a good case study to refer. Download white paper from here.

• SQL SERVER – Auto Recovery File Settings in SSMS – SQL in Sixty Seconds #034 – Video

  - by pinaldave

  Every developer once in a while facing an unfortunate situation where they have not yet saved the work and their SQL Server Management Studio crashes. Well, you can minimize the loss by optimizing auto recovery settings. In this video we can see how to set the auto recovery settings. Go to SSMS >> Tools >> Options >> Environment >> AutoRecover There are two different settings: 1) Save AutoRecover Information Every Minutes This option will save the SQL Query file at certain interval. Set this option to minimum value possible to avoid loss. If you have set this value to 5, in the worst possible case, you can loose last 5 minutes of the work. 2) Keep AutoRecover Information for Days This option will preserve the AutoRecovery information for specified days. Though, I suggest in case of accident open SQL Server Management Studio right away and recover your file. Do not procrastinate this important task for future dates.
