I have a testdata like this:

DROP TABLE SELECT_PASS;
CREATE TABLE SELECT_PASS(ID INT(20),TESTCASE VARCHAR(20),RESULT VARCHAR(20));
INSERT INTO SELECT_PASS VALUES(1,"TC1","PASS");
INSERT INTO SELECT_PASS VALUES(2,"TC2","PASS");
INSERT INTO SELECT_PASS VALUES(3,"TC3","INCONC");
INSERT INTO SELECT_PASS VALUES(4,"TC1","FAIL");
INSERT INTO SELECT_PASS VALUES(5,"TC21","FAIL");
INSERT INTO SELECT_PASS VALUES(6,"TC4","PASS");
INSERT INTO SELECT_PASS VALUES(7,"TC3","PASS");
INSERT INTO SELECT_PASS VALUES(8,"TC2","PASS");
INSERT INTO SELECT_PASS VALUES(9,"TC1","TIMEOUT");


SELECT TESTCASE, MAX(RESULT) FROM SELECT_PASS  GROUP BY TESTCASE;

The resultset I get is :

TC1 TIMEOUT
TC2 PASS
TC21    FAIL
TC3 PASS
TC4 PASS

Basically I want to see those testcases which never passed.

Any way to do it?

Thanks.
