Hi All ,

This is my query it takes 30 second to process . I need to optimize it pls provide me some solution. I also heard about EXPLAIN PLAN what is that?

                          Select  unique api\_WEEKLY.country From api\_WEEKLY INNER JOIN USERPROFILE

                               ON api\_WEEKLY.REGION  = NVL(USERPROFILE.REGION,api\_WEEKLY.REGION)

                               AND api\_WEEKLY.Category = NVL(USERPROFILE.SECTOR,api\_WEEKLY.Category)

                               AND api\_WEEKLY.MRP\_DRP\_CONTROLLER  = NVL(USERPROFILE.MRP\_DRP\_CONTROLLER,api\_WEEKLY.MRP\_DRP\_CONTROLLER)

                               AND api\_WEEKLY.TDC\_VAL = NVL(USERPROFILE.TDC\_VAL,api\_WEEKLY.TDC\_VAL)

                               AND api\_WEEKLY.PLANT  = NVL(USERPROFILE.PLANT,api\_WEEKLY.PLANT)

                                AND api\_WEEKLY.MATERIAL = NVL(USERPROFILE.MATERIAL,api\_WEEKLY.MATERIAL)

                               AND api\_WEEKLY.SUBSECTOR  = NVL(USERPROFILE.SUBSECTOR,api\_WEEKLY.SUBSECTOR)

                               AND api\_WEEKLY.COUNTRY = NVL(USERPROFILE.COUNTRY,api\_WEEKLY.COUNTRY)

                               WHERE USERPROFILE.USER\_ID = 'sheikh.a' ;
