Hi Maahi Just post the table Structure and requirement. As per your last post I came to know you want to insert some data in table JTSDataExcel when some condition match which you checked You can do all the thing in sinle insert with Join. You can make some changes in your query also. Remove Distinct in Exists() use Select Top 1 1 from TableName where condition Secound in first condition match you again check secound contion and insert data in else so change the condition exist with not exists and add you insert code inside that block. Which I found most critcal is your query for comment 'Preparer, Reviewer and QA cannot be the same' is not sync with exists condition. This shuld be given some unconstant response. Might be you face this?

Below is the query: I need to optimize the query i.e, here i need to check bulk of data on each step which ever record valid that menas match with the condition if will check to next 2nd condition otherwise unmatched data will go in else record WHILE (@i BEGIN If Exists(select distinct id, tjts.* from Client_Service_Master csm inner join #tempJTSData tjts on csm.Client_Code = tjts.Client_Name where tjts.id= (@i) and csm.Client_Code = tjts.Client_Name and csm.Service_Type_Code = tjts.Service_Names and csm.Status ='Active' ) Begin If Exists(select distinct id, tjts.* from #tempJTSData tjts where tjts.id= (@i) and tjts.Preparer tjts.Reviewer and tjts.Reviewer tjts.QA and tjts.QA tjts.Preparer ) Begin print 'hi' End else Begin INSERT into JTSDataExcel (Client_Name,Service_Names ,File_Names ,Type_Of_Work ,Date_In ,Budgetted_Hrs ,Mode_Of_Receipt,Job_Status , Billed_Hrs ,Date_Out ,Manager ,Team_Leader ,Preparer ,Prep_Hrs ,Reviewer ,Review_Hrs , QA ,QA_Hrs,Comments ) select top 1 tjts.Client_Name,tjts.Service_Names ,tjts.File_Names ,tjts.Type_Of_Work ,tjts.Date_In ,tjts.Budgetted_Hrs ,tjts.Mode_Of_Receipt,tjts.Job_Status ,tjts.Billed_Hrs , tjts.Date_Out,tjts.Manager ,tjts.Team_Leader ,tjts.Preparer ,tjts.Prep_Hrs ,tjts.Reviewer ,tjts.Review_Hrs ,tjts.QA ,tjts.QA_Hrs,'Preparer, Reviewer and QA cannot be the same' from #tempJTSData tjts where tjts.id= (@i) and tjts.Preparer = tjts.Reviewer OR tjts.Reviewer = tjts.QA OR tjts.Preparer = tjts.QA End SET @i = @i + 1 End Else --Client & Service Name Does not Exists Begin Insert into JTSDataExcel (Client_Name,Service_Names ,File_Names ,Type_Of_Work ,Date_In ,Budgetted_Hrs ,Mode_Of_Receipt,Job_Status , Billed_Hrs ,Date_Out ,Manager ,Team_Leader ,Preparer ,Prep_Hrs ,Reviewer ,Review_Hrs , QA ,QA_Hrs,Comments ) select top 1 tjts.Client_Name,tjts.Service_Names ,tjts.File_Names ,tjts.Type_Of_Work ,tjts.Date_In ,tjts.Budgetted_Hrs ,tjts.Mode_Of_Receipt,tjts.Job_Status ,tjts.Billed_Hrs , tjts.Date_Out,tjts.Manager ,tjts.Team_Leader ,tjts.Preparer ,tjts.Prep_Hrs ,tjts.Reviewer ,tjts.Review_Hrs ,tjts.QA ,tjts.QA_Hrs, 'Client Name & Service Name not exists' from #tempJTSData tjts inner join Client_Service_Master csm on tjts.Client_Name != csm.Client_Code where tjts.id= (@i) End SET @i = @i + 1 END select * from JTSDataExcel
