Question

How can I get the month number in sql? I use the following code but it returns the month name.

SELECT DATENAME(mm, GETDATE())

Answer 1

This will return with two char in case of Jan-Sep:

SELECT CASE WHEN LEN(MONTH(GETDATE())) = 1 THEN '0' + CAST(MONTH(GETDATE()) AS VARCHAR(2)) 
WHEN LEN(MONTH(GETDATE())) = 2 THEN CAST(MONTH(GETDATE()) AS VARCHAR(2)) END
