I use DATEDIFF function to filter records added this week only:
DATEDIFF(week, DateCreated, GETDATE()) = 0
and I noticed what it's assumed what week starts on Sunday. But in my case I would prefer to set start of week on Monday. Is it possible somehow in T-SQL?
Thanks!
Update:
Below is an example showing what DATEDIFF doesn't check @@DATEFIRST variable so I need another solution.
SET DATEFIRST 1;
SELECT
DateCreated,
DATEDIFF(week, DateCreated, CAST('20090725' AS DATETIME)) AS D25,
DATEDIFF(week, DateCreated, CAST('20090726' AS DATETIME)) AS D26
FROM
(
SELECT CAST('20090724' AS DATETIME) AS DateCreated
UNION
SELECT CAST('20090725' AS DATETIME) AS DateCreated
) AS T
Output:
DateCreated D25 D26
----------------------- ----------- -----------
2009-07-24 00:00:00.000 0 1
2009-07-25 00:00:00.000 0 1
(2 row(s) affected)
26 Jul 2009 is Sunday, and I want DATEDIFF returns 0 in third column too.
