GO 100000 - Learning something every day, today it's the SQL Server/TSQL GO Statement has a parameter...

SQL Server with Mr. Denny - Quick and dirty way to run a batch over and over

"Everyone has their favorite way or running a block of code over and over again. If you have to run an entire batch over and over again there is nothing as quick and easy as using the “GO n” syntax. When you put a number after the GO batch separator SQL Server Management Studio (as well as SQLCMD) will run that entire batch however many times that you have specified.

Recently I needed to create some dummy data in a table, so instead of writing a loop that counted the number of times the loop ran, I simply used code like this.



This just made me shake my head and sigh at just how much I don't know. I've been using SQL Server since 4.21a, writing and dreaming in T-SQL, and I never knew the GO statement had a [Count] parameter (as in repeat the given statement [Count] times... sigh.
