i have a query that returns 2 rows with one column being id and the other being date-time stamp.

i want to select the row with the latest timestamp among those two records.they have difference id values

SELECT ID,LastModDate
FROM Tab

ID	LastModDate
--	-----------
2	1/20/2003 2:56:18 AM
1	4/23/2003 10:26:42 PM

I want to modify the above query to return the row with id=1 which has the latest timestamp

I tried this

SELECT ID,MAX(LastModDate)
FROM Tab

getting this error
OERR: ORA 937 not a single-group group function

how do i get this work.

Thanks
