I Have a simple query that i am running. but i need the
results to only show each month only once, this one has
stumpted me! :)
I know why it is happening but i cant solve it

SO should i be using a cast command or somthing else to
get around this problem?

Below is my query and the result of when it is run.

Willa

SELECT

DATENAME(YEAR,SAIL_DAT) AS SAIL_YEAR,
DATENAME(MONTH,SAIL_DAT) AS SAIL_MONTH

FROM dbo.IPS_POINTS

WHERE RES_AGENT_CD = 'PLUMB_N'

GROUP BY DATENAME(YEAR,SAIL_DAT),DATENAME
(MONTH,SAIL_DAT),SAIL_DAT

ORDER BY SAIL_DAT
