Will someone help me out with this query?
Maybe I am misinterpreting your question, because this seems like a standard GROUP BY query.... creating some test data: use test; create table lewis (f1 int,f2 int,f3 int); insert into lewis values (1,0,10000); insert into lewis values (1,0,10001); insert into lewis values (2,0,10021); insert into lewis values (2,0,10022); insert into lewis values (3,0,10032); insert into lewis values (3,0,10033); mysql> select * from lewis; +------+------+-------+ | f1 | f2 | f3 | +------+------+-------+ | 1 | 0 | 10000 | | 1 | 0 | 10001 | | 2 | 0 | 10021 | | 2 | 0 | 10022 | | 3 | 0 | 10032 | | 3 | 0 | 10033 | +------+------+-------+ 6 rows in set (0.00 sec) mysql> select f1,min(f3) from lewis group by f1; +------+---------+ | f1 | min(f3) | +------+---------+ | 1 | 10000 | | 2 | 10021 | | 3 | 10032 | +------+---------+ 3 rows in set (0.09 sec) Is this what you wanted?
