| Hi. Hope everyone doing great. When i run SELECT 'X' FROM PS_INSTALLATION this it's taking no time, and when i run the inner query it's taking 3 sec. But when i run the compete query it's taking 2 mins. This is system generated query i can't change the query. Execution plans for the query and inner query are different.CODE:SELECT 'X' FROM PS_INSTALLATION WHERE EXISTS (SELECT 'X' FROM PS_KK_SOURCE_LN A, PS_KK_SOURCE_HDR B , PS_KK_ACTIVITY_LOG C WHERE B.BUSINESS_UNIT = 'BUS' AND B.PO_ID = 'PO_NUM' AND A.LINE_NBR = '1' AND A.SCHED_NBR = '1' AND A.DISTRIB_LINE_NUM = '1' AND A.KK_TRAN_ID = B.KK_TRAN_ID AND A.KK_TRAN_DT = B.KK_TRAN_DT AND A.KK_TRAN_ID = C.KK_TRAN_ID AND A.KK_TRAN_DT = C.KK_TRAN_DT AND A.KK_TRAN_LN = C.KK_TRAN_LN AND C.ENTRY_EVENT <> ' ' AND C.EE_PROC_STATUS IN ('N', ' '))Any help would be greatly appreciated!Thanks,Best Regards,Kumar. |
