RE: SQL Question

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

Is this supposed to be a single row only?  Or could you have several rows for 
the earlies date?  For now, I'll assume the second.

With Hx (Div, Acct, PO#, HxBegin) as
(       Select Division, Account, PO#, 
                 Min(ChgDtCen*1000000 + ChgDt6)
        From     MyFile
        Group By Division, Account, PO#
)

Select a.* 
from     MyFile a inner join
         Hx on(a.Division=Hx.Div and 
                 a.Account=Hx.Acct and
                 a.PO#=Hx.PO# and
                 ChgDtCen*1000000+ChgDt6=Hx.HxBegin)

hth,
Eric

I have a history file with the following fields :
Division
Account
PO#
Date Changed YYMMDD
Date Changed Century  1/0
Cancel Date 
 Old / New Code  O/N
.
.
.
.
 
Is there a way using SQL to select the data from the record with the oldest 
date for a given Division, Account & PO#.

TIA,
