I would use this   SELECT  Closing Date   DATEADD MONTH  DATEDIFF MONTH  0  Closing Date   0            Category            COUNT Status  TotalCount  FROM    MyTable WHERE   Closing Date  gt    2012-02-01   AND     Closing Date  lt    2012-12-31  AND     Defect Status1 IS NOT NULL GROUP BY DATEADD MONTH  DATEDIFF MONTH  0  Closing Date   0   Category    This will group by the first of every month  so    DATEADD MONTH  DATEDIFF MONTH  0   20130128    0      will give  20130101   I generally prefer this method as it keeps dates as dates   Alternatively you could use something like this   SELECT  Closing Year   DATEPART YEAR  Closing Date           Closing Month   DATEPART MONTH  Closing Date           Category            COUNT Status  TotalCount  FROM    MyTable WHERE   Closing Date  gt    2012-02-01   AND     Closing Date  lt    2012-12-31  AND     Defect Status1 IS NOT NULL GROUP BY DATEPART YEAR  Closing Date   DATEPART MONTH  Closing Date   Category    It really depends what your desired output is   Closing Year is not necessary in your example  but if the date range crosses a year boundary it may be
