How to show field that not being group? - 07-30-2008 , 09:51 PM

Hi all.

I have this data:

id GroupId DDate Value
1 1 7/31/2008 5
2 1 7/31/2008 6
3 1 7/31/2008 2
4 2 7/31/2008 1
5 2 7/31/2008 2
6 2 7/31/2008 1

From this raw dataI want to show the data like this"
GroupId DDate TotalValue
1 7/31/2008 13
2 7/31/2008 4

current Query that I Use is

Select D.GroupId,(Select Top 1 DDate From MyTable Where
GroupId=D.GroupId)As DDate, Sum(D.Value) As TotalValue From MyTable D
Group By D.GroupId

But I want to remove the subquery, so my query will run faster.

Could it be done?

Thanks in Advanced

Use the Max(...) aggregate function similar to the Sum(...) aggregate
you are already using.
