You cannot mix grouping columns without a group by clause. This would work: SELECT * FROM MYTABLE order by ifield desc limit 1 Elna Moorhouse wrote:
TRY: SELECT id,Max(ifield) from MYTABLE. What I don't understand is why you specify id=$id in the where clause. If you already specify the id as let say 1 then the max for that id will be 100 from your example below. "Richard Fox" <rfox@sbsii.com> wrote in message news:003901c2b034$0c563740$0700a8c0@mygroup... Hi, What would be a query to select a single record from a number of records in a table, depending on which one has the biggest value in an integer field? e.g something like: MYTABLE ------------
id       ifield
1        100
2        200
3        150
SELECT * FROM MYTABLE WHERE id=$id and MAX(ifield) should return id=2, ifield=200 (but this doesn't work, of course) Many thanks, Richard
