As such, I thought it would be worthwhile sharing some TSQL scripts that I have been using over the years for tuning SQL Server queries. So what I am generally looking for are:Long Running Queries – which queries are taking the longest to run CPU Intensive Queries – whic...
How can I see what queries were executed at a specific time? How can i select a max of column witch type is unique identifier how can i select all columns except one in sql server query How can i select the step count of a recursive CTE ? How can i set value of @variable inside ...
And for some queries it makes a huge difference.Example 2: Faster way find indexes on User Tables.Perhaps you want to see all the Indexes in your system but don’t want the results cluttered with indexes on the System Catalog. Unfortunately when you query the Sys....

queries in the report designers,please, get into the habit of copying/pasting the report queries to/from the designer and SSMS. Once you get used to declaring/setting parameter values when running in SSMS, and then commenting them out in the designers, life will become much m...

Here is the screen shot with the inputs and the computations for tmin gini scores. These inputs and computations are displayed through a series of eight queries. The screen shot below shows the results set from each of the eight queries. ...
the script. I always like to do this for long-running scripts, so that I can see it is still busy, and also see which parts are running slow (in case I need to do further optimizations). If you switch SSMS to “output to text” (Ctrl-T) before running the script, you will see...
