Inserting Data from Source to Destination

Question

I have a query to insert data from source to destination table in sql server.Records from source table should be inserted into destination table if they are not present in destination table and if records are present they should be updated.

 

Source Table is [DistributorPortal].cdgmaster.Customer

Destination Table is cdgmaster.Customer

 

I have written the following procedure

 

ALTER PROCEDURE [dbo].[Distributor_Portal_Lakshaya_Source_Destination_Update]
AS
BEGIN
Begin Try
Declare @sourcerecords int;
Declare @destinationrecords int;
Select @destinationrecords = Count(*) from [DistributorPortal].cdgmaster.Customer where CustomerCode in (Select CustomerCode from cdgmaster.Customer)
Select @sourcerecords = Count(CustomerCode) from cdgmaster.Customer
If @destinationrecords < @sourcerecords
Begin
Insert into [DistributorPortal].cdgmaster.Customer (CustomerCode,CustomerName,CustomerAddress1,CustomerAddress2,CustomerAddress3,CustomerID,SAPID,RegionCode,ZoneCode,TerritoryCode,StateCode,TownCode,TypeCode,PSnonPS,EmailID,MobileLL,SuppliedBy,DrugLicense,CurrentYTD,DSByChannelCode,DSByStrategicCode,ClassificationCode,IsActive,DeactiveDt,ActiveDt,AnnualIncentivePlan,isTarangUmang,WholeSalerCode,isIME,createdBy,NKACStores,ParentCustomerCode,IsDirectAcct,ABICode,DistributorCode,DistributorSAPID,SAPZoneCode,SAPTerritoryCode,IsConfirm,NkacRegion,NkacZone,NkacTerritory,Channel,GLN,TransitDays,TransitHours,VMRApply) Select CustomerCode,CustomerName,CustomerAddress1,CustomerAddress2,CustomerAddress3,CustomerID,SAPID,RegionCode,ZoneCode,TerritoryCode,StateCode,TownCode,TypeCode,PSnonPS,EmailID,MobileLL,SuppliedBy,DrugLicense,CurrentYTD,DSByChannelCode,DSByStrategicCode,ClassificationCode,IsActive,DeactiveDt,ActiveDt,AnnualIncentivePlan,isTarangUmang,WholeSalerCode,isIME,createdBy,NKACStores,ParentCustomerCode,IsDirectAcct,ABICode,DistributorCode,DistributorSAPID,SAPZoneCode,SAPTerritoryCode,IsConfirm,NkacRegion,NkacZone,NkacTerritory,Channel,GLN,TransitDays,TransitHours,VMRApply from cdgmaster.Customer where CustomerCode not in(Select CustomerCode from cdgmaster.Customer)
