I've got a column with all these different dates, and need to select just the unique month + year.

Example of dates:
2007-5-01
2007-5-13
2007-5-28
2007-6-15
2007-6-15
2007-8-01

and with the query I just want to pull:
MAY 2007
JUNE 2007
AUGUST 2007

is this possible :( ? And can anyone point me in the right direction as to how I would go about this?

You can try convert that with substring function and case statement.

[code]

select distinct
Start_Of_Month =dateadd(month,datediff(month,0,MyDate),0),
Year = Year(Mydate),
Month = datename(month,Mydate)
from
(
select MyDate = getdate() union all
select '2007-5-01' union all
select '2007-5-13' union all
select '2007-5-28' union all
select '2007-6-15' union all
select '2007-6-15' union all
select '2007-8-01'
) a
order by 1

Here is a sample that can get you started:

DECLARE @T TABLE (A DATETIME)

INSERT @T
SELECT '2007-5-01'
UNION ALL SELECT '2007-5-13'
UNION ALL SELECT '2007-5-28'
UNION ALL SELECT '2007-6-15'
UNION ALL SELECT '2007-6-15'
UNION ALL SELECT '2007-8-01'

SELECT
	DATENAME(MONTH,A),
	YEAR(A),
	COUNT(*)
FROM
	@T t
GROUP BY
	YEAR(A),
	DATENAME(MONTH,A)

wow thanks a lot! and I'm supposing I can use a concat function to just group the month and year as 1 field, right?
