--SELECT * FROM @tempTbl---it runs ok



UPDATE dbo.Customers
 SET
                     dbo.Customers.Customer_name =  @tempTbl.Customer_name, 
                     dbo.Customers.Customer_Code = @tempTbl.Customer_Code
from dbo.Customers
                inner join @tempTbl
                    on Customers.tblID =@tempTbl.tblID

Answer 1

Try aliasing the table variable in the UPDATE

e.g.

UPDATE dbo.Customers
SET
                 dbo.Customers.Customer_name =  tmp.Customer_name, 
                 dbo.Customers.Customer_Code = tmp.Customer_Code
from dbo.Customers
            inner join @tempTbl tmp
                on Customers.tblID = tmp.tblID
