IF/MAX statement help needed

[#1]

am trying to get the following IF statement to work, and I'm not sure this is possible and if so, what I'm doing wrong. I have a couple of questions. Do I need a Group By function added to this? If so, where, because I've tried it several ways. Also, can this even be done the way I'm trying to do things?

GPAStatusTbl:
SQL SELECT * FROM SYSADM."PS_W_GPA_STS_TBL";
STORE * FROM GPAStatusTbl INTO $(vQVDFolder)\GPAStatusTbl.qvd;
DROP TABLE GPAStatusTbl;
LOAD
"W_GPA_ID" AS [IHR GPA ID],
ACTIONDTTM,
"W_GPA_STATUS",
IF(W_GPA_STATUS = 'IHV', MAX (ACTIONDTTM)) AS IHR_APP_1_DATE
FROM $(vQVDFolder)\GPAStatusTbl.qvd (qvd);

Thanks!

Try: MAX(IF(W_GPA_STATUS = 'IHV', ACTIONDTTM)) AS IHR_APP_1_DATE

And yes, you would need to group it by first 3 fields.

EDIT: And I think you need to use MAXSTRING and not MAX as W_GPA_STATUS seems to be a string.
