I think that the last line is the problem and that you have to change it to AND D1.EFFDT <= TO_DATE('01-JAN-2002', 'DD-MON-YYYY')); I think that he is converting D1.EFFDT to char-format instead of converting '01-JAN-2002' to date-format.

Best regards,

Oracle Gurus,

I have a perplexing problem....I recently installed Oracle 8.1.7.0 (64 bit) on an HP 11.X (64 bit) machine running a HRMS/PAyroll type application. I am having a problem with the below sql statement not returning any rows. When I look at the data, a row should be returned. Any ideas or solutions to this problem? Also, when I execute the subselect as a standalone SQL, a row of data is returned.

SELECT SETID,
EFFDT
FROM PSTREEDEFN D
WHERE D.EFF_STATUS = 'A'
AND D.TREE_NAME = 'DEPT_SECURITY'
AND D.EFFDT = (SELECT MAX(D1.EFFDT)
FROM PSTREEDEFN D1
WHERE D1.SETID = D.SETID
AND D1.TREE_NAME = D.TREE_NAME
AND D1.EFFDT <= '01-JAN-2002');

Willie
