Fighting With Dates Trying To Lookup Month And Year

Hi all I this stored procedure is suppose to turn give the users the ability to put the month and date in so they can see how many each inspector did for that month and year.



Create Procedure LookupYearMonth
AS
SELECT I.[Last Name], I.[First Name],
[Date by Month] = DATENAME(month, MT.[Date] + ' ' + DATENAME(year, MT.[DATE]),
[Count Of Main Table] = count(*)
FROM Inspectors I
INNER JOIN [Main Table] MT
ON (I.ID = MT.Inspector)
GROUP BY I.[Last Name], I.[First Name],
DATENAME(month, MT.[Date] + ' ' + DATENAME(year, MT.[DATE])
WHERE (MT.[Date] >= CONVERT(datetime, @EnterMonthYear)) AND
(MT.[Date] < DATEADD(month, 1, CONVERT(datetime, @EnterMonthYear)))

GO
