I have a query joining two tables but is returning duplicate data even though I am grouping?
Example:
Select L.Client, L.FltNbr, L.LegNbr, G.Acct as MEALS, G.DRAmt, G.PerPost
From xLegHdr L
Inner Join
(Select ProjectID,Acct,DrAmt,PerPost
From GLTran
Group By ProjectID,Acct,DrAmt,PerPost) G
ON L.FltNbr = G.ProjectID
Where G.Acct = '530002'
AND G.PerPost Between '200601' AND '200612'

Any Suggestions on how to better group the data so there are not duplicates?

Thanks,

Which query is returning duplicates? The inner one or the outer one?
Use a GROUP BY on the outer select and see if it makes any difference.

It did not make a difference. Both queries return duplicates and using the Group By on the outer Select
did not work.

Can you post some sample data from each table and expected output?

can you not use distinct?


Select distinct L.Client, L.FltNbr, L.LegNbr, G.Acct as MEALS, G.DRAmt, G.PerPost...

I tried the following query and I'm still getting duplicates.
Select Distinct L.Client, L.FltNbr, L.LegNbr, G.Acct as MEALS, G.DRAmt, G.PerPost
From xLegHdr L
INNER JOIN GlTran G ON G.ProjectID = L.FltNbr
Where G.Acct = '530002'
AND G.PerPost Between '200601' AND '200612'
Group by L.Client, L.FltNbr, L.LegNbr, G.Acct, G.DrAmt, G.PerPost

if any of the fields are datetime then you will probably have a problem. datetime tracks to the 1/3 of a second, iirc.
