SQL to run on specific date time

http://www.sqlservercurry.com/2010/10/execute-t-sql-code-only-on-certain-days.html

I always clean up my databases manually on Sundays. But at times, if need be, I clean it up on other days as well. However I never do it on Saturdays, since the traffic is usually the most on that day.

So here’s a simple tip using IF-ELSE to prevent my T-SQL code from running on Saturday’s, even if I run the code manually

IF DATEPART(dw,GETDATE())<> 7  -- 7 is Saturday, 1 is SundayBEGIN
    -- YOUR T-SQL Code Comes Here   
     SELECT GETDATE()
     RETURN
END
ELSE
BEGIN
    PRINT '*** Sorry This Code will Not Execute on Saturdays'END

OUTPUT
