Multiple condition Query

Question

Hello
I have a result of Query like this:
Col1 Col2 Col3
T1 15 20
T1 18 19
T1 5 20
T2 15 20
T2 18 19
And I just need to display only the T's that would meet the condition Col2 in (15,18) and Col3 in (20,19).
I try with a condition where col2 in (15,18) and col3 in (20,19) and that works, but I don't need to display T1, because T1 has a Col2=5 and Col3=20, I just have to display T2 that just satisfies all my conditions, Col2 in (15,18) and Col3 in (20,19). It's something like a vertical search.
How can I do it?

Welcome to the forum!
Whenever you have a question, please post CREATE TABLE and INSERT statements for your sample data, and also post the results you want from that data. You should explain how you get the results, as you did, but explain them in addition to, not instead of posting them.
Always say which version of Oracle you're using.
Since this is your first message, I'll post the sample data for you:
CREATE TABLE     table_x
(     col1     VARCHAR2 (5)
,     col2     NUMBER (2)
,     col3     NUMBER (2)
INSERT INTO table_x (col1, col2, col3) VALUES ('T1', 15, 20);
INSERT INTO table_x (col1, col2, col3) VALUES ('T1', 18, 19);
INSERT INTO table_x (col1, col2, col3) VALUES ('T1',  5, 20);
INSERT INTO table_x (col1, col2, col3) VALUES ('T2', 15, 20);
INSERT INTO table_x (col1, col2, col3) VALUES ('T2', 18, 19);
COMMIT;I think (but I'm not sure) the results you want are just the col1s that always meet the conditions:
COL1
T2You can get these results with MINUS, but it requires two passes through the data. It will be more efficient to get all the information you need in one pass, like this:
SELECT       col1
FROM       table_x
GROUP BY  col1
HAVING       SUM ( CASE
               WHEN  col2 IN (15, 18)
               AND   col3 IN (19, 20)
               THEN  0
               ELSE  1
          END
           ) = 0
;If you want the results that Skud posted, then you can do something similar, using the analytic SUM function instead of the aggregate SUM.
Can col2 or col3 be NULL? If so, post some sample data and results where they are.
This query will work in Oracle 8.1 (and higher).
