Execute T-SQL Code Only on Certain Days

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 Sunday
BEGIN
-- YOUR T-SQL Code Comes Here
SELECT GETDATE()
RETURN
END
ELSE
BEGIN
PRINT
'*** Sorry This Code will Not Execute on Saturdays'
END

OUTPUT

Hi There,

DATEPART() function does not return the same value in all the situations since it depends on the settings of SET DATEFIRST option. Instead use DATENAME() function.

Refer to the following links for more details:
