How can I select the first day of a month in SQL?
Posted By: Anonymous
I just need to select the first day of the month of a given datetime variable.
I know it’s quite easy to do using this kind of code:
select CAST(CAST(YEAR(@mydate) AS VARCHAR(4))
+ '/' + CAST(MONTH(@mydate) AS VARCHAR(2)) + '/01' AS DATETIME)
But this is not very elegant, and probably not very fast either.
Is there a better way to do this? I’m using SQL Server 2008.
Solution
SELECT DATEADD(month, DATEDIFF(month, 0, @mydate), 0) AS StartOfMonth
