I took this particular code from http://weblogs.sqlteam.com/jeffs/archive/2007/09/10/group-by-month-sql.aspx,
a good read. Shows you what to avoid and why.
The recommended technique is the following:
GROUP BY dateadd(month, datediff(month, 0, SomeDate),0)
By the way, in the "select" clause, you can use the following:
SELECT
month(dateadd(month, datediff(month, 0, SomeDate),0)) as [month],
year(dateadd(month, datediff(month, 0, SomeDate),0)) as [year],
Just remember to also sort properly if needed:
ORDER BY dateadd(month, datediff(month, 0, SomeDate),0)
