Hello Tech gents! I am sorry if I am asking the wrong question to this group, but wanted assistance in converting a query replacing subqueries with joins.
Please find the query below (whose cost is very high): select em_exists_id from IS_SEC_FILT WHERE (IS_SEC_FILT_GUID) NOT IN (SELECT IS_OBJ_GUID FROM TMP_IS_SEC_FILT T0, IS_PROJ P0 WHERE T0.IS_PROJ_GUID = P0.IS_PROJ_GUID AND P0.IS_PROJ_ID = IS_SEC_FILT.IS_PROJ_ID) AND (IS_PROJ_ID) IN (SELECT IS_PROJ_ID FROM IS_PROJ P0, TMP_IS_SEC_FILT T0, EM_MD R0 WHERE T0.IS_REPOSITORY_GUID = R0.REP_GUID AND T0.IS_PROJ_GUID = P0.IS_PROJ_GUID AND P0.IS_REPOSITORY_ID = R0.REP_ID); Regards Siraj
