che ne dici di questo:
INSERT INTO TBL_RESULT (ID, TBL1_ID, TBL2_ID)
SELECT seq_tbl_result.nextval,t1.id,t2.id
FROM
(SELECT t1.match_criteria,t1.id, row_number() OVER (PARTITION BY t1.match_criteria ORDER BY t1.id) rn
FROM tbl1 t1) t1,
(SELECT t2.match_criteria,t2.id, row_number() OVER (PARTITION BY t2.match_criteria ORDER BY t2.id) rn
FROM tbl2 t2) t2
WHERE t1.match_criteria=t2.match_criteria AND t1.rn=t2.rn
Nota:presuppone che ci sia un numero uguale di righe in ogni set di corrispondenza in entrambe le tabelle.
