TSQL retrieve all records in current month/year

Question

I have a datetime field called DateFinished. I need to be able to retrieve all records in which DateFinished is within the current month/year.

Answer 1

Just as an alternative - this should use an index on DateFinished.

SELECT * 
FROM MyTable
WHERE DateFinished BETWEEN 
     DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0)
     AND 
     DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) + 1, 0)
