I have the following in a table:
oid | citkey | contby | contdate | abcontinue | ccdate
---------+------------+----------+------------+------------+------------
5774835 | 04-0594703 | | | |
5775325 | 04-0594703 | Attorney | 04/06/2005 | 6 | 03/07/2005
5776060 | 04-0594703 | Attorney | 05/04/2005 | 6 | 04/05/2005
5776067 | 04-0594703 | Attorney | 05/04/2005 | 6 | 04/05/2005
I am trying to pull rows that have the max. contdate. Why does the
following give more than 2 rows?
ql "select oid,* from ccontinue where citkey ='04-0594703' group by
oid,citkey,contby,contdate,abcontinue,ccdate having max(contdate) =
contdate"
oid | citkey | contby | contdate | abcontinue | ccdate
---------+------------+----------+------------+------------+------------
5776067 | 04-0594703 | Attorney | 05/04/2005 | 6 | 04/05/2005
5775325 | 04-0594703 | Attorney | 04/06/2005 | 6 | 03/07/2005
5776060 | 04-0594703 | Attorney | 05/04/2005 | 6 | 04/05/2005
(3 rows)
thanks
