Sir below query takes more nd more time.... select sum(T.TQty)TQty,sum(T.SQty)SQty from ( select count(OuterboxNo)as TQty,0 as SQty from wms_bulk_transaction where status='PUT' and concept='FL' and slot_code in (select slot_code from wms_slot_master slt,wms_aielse_master ail where slt.aielse_code=ail.aielse_code and ail.aielse_type='HR' and cyclecountnumber='CNT1300005') union select count(MonoboxNo)as TQty,0 as SQty from wms_loose_transaction where status='PUT' and concept='FL' and slot_code in (select slot_code from wms_slot_master slt,wms_aielse_master ail where slt.aielse_code=ail.aielse_code and (ail.aielse_type='SA' OR ail.aielse_type='MA') and cyclecountnumber='CNT1300005') union select 0 as TQty,count(OuterboxNo) as SQty from wms_bulk_transaction where status='PUT' and concept='FL' and slot_code in (select slot_code from wms_slot_master slt,wms_aielse_master ail where slt.aielse_code=ail.aielse_code and ail.aielse_type='HR' and cyclecountnumber='CNT1300005') and (cyclecountdone='CNT1300005' or cyclecountdone is not null) union select 0 as TQty,count(MonoboxNo) as SQty from wms_loose_transaction where status='PUT' and concept='FL' and slot_code in (select slot_code from wms_slot_master slt,wms_aielse_master ail where slt.aielse_code=ail.aielse_code and (ail.aielse_type='SA' OR ail.aielse_type='MA') and cyclecountnumber='CNT1300005') and (cyclecountdone='CNT1300005' or cyclecountdone is not null) )T
