How to get week number of the month from the date in sql server 2008

Question

In SQL Statement in microsoft sql server, there is a built-in function to get week number but it is the week of the year.

Select DatePart(week, \'2012/11/30\         


        

Answer 1

Logic here works as well 4.3 weeks in every month. Take that from the DATEPART(WEEK) on every month but January. Just another way of looking at things. This would also account for months where there is a 5th week

DECLARE @date VARCHAR(10)
SET @date = '7/27/2019'

SELECT CEILING(DATEPART(WEEK,@date)-((DATEPART(MONTH,@date)-1)*4.3333)) 'Week of Month'
