I have below query and wanted to know if this can be re-written in a better way?
SELECT COL1, COL2 FROM TABLE1 WHERE ID = 1 and COL4 = 1415 AND COL3 IN
(SELECT MAX(COL3) FROM TABLE1 WHERE PRI = ID = 1 and COL4 = 1415);
The question arises from the fact that filters ID and Col4 in where clause of subquery are same as the filters in the main query.
You can use:
SELECT COL1, COL2,MAX(COL3) as mx FROM TABLE1 WHERE ID = 1
and COL4 = 1415 having mx=MAX(COL3);
This will avoid the extra sub-query.
