Hi,
I hava a table with the following information -
CREATE TABLE TEMP1 (REFID INT, REVISION INT, FIELDNAM VARCHAR(10), VALUE VARCHAR(10));
-
INSERT INTO TEMP1 VALUES(1001, 0, 'A', 'A2');
-
INSERT INTO TEMP1 VALUES(1001, 0, 'C', 'C2');
-
INSERT INTO TEMP1 VALUES(1001, 0, 'E', 'E2');
-
INSERT INTO TEMP1 VALUES(1002, 0, 'A', 'A3');
-
INSERT INTO TEMP1 VALUES(1002, 0, 'B', 'B2');
-
INSERT INTO TEMP1 VALUES(1002, 0, 'E', 'E3');
-
INSERT INTO TEMP1 VALUES(1001, 1, 'A', 'A4');
-
INSERT INTO TEMP1 VALUES(1001, 1, 'E', 'E4');
-
Here based on latest revision and refid I should get the fieldnam and value.
Expected output:
REFID FIELDNAM VALUE REVISION
1001 A A4 1
1001 E E4 1
1002 B B2 0
1001 C C2 0

Try this: -
-
SELECT x.refid, x.fieldnam, t.value, x.revision FROM
-
(SELECT MAX(revision),refid,fieldnam FROM temp1 GROUP by refid,fieldnam) x, temp1 t
-
WHERE t.refid = x.refid
-
AND t.revision = x.revision
-
AND t.fieldnam = x.fieldnam
