SQL Server, T/SQL
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.
CREATE TABLE SampleData (id int identity(1,1), SomeData varchar(100)) go insert into SampleData (SomeData) values ('This is my sample data') go 100000
When run, the batch with the insert statement ran 100,000 times generating all the data that I needed with just 7 extra keystrokes.
