One way this can be achieved is to put the rows to insert into a temporary table and then select from the temporary table only the rows that do not exist in the table where you want to insert the data finally.

Step 1: Select all rows to insert into myTblModels

Step 2: Select from myTblModels where row does not exists in final table.Insert these rows into final table:

Insert into tblModels(column1,column2,....)

Select *

From myTblModels t

Where Not Exists(Select 1 From tblModels f Where t.key1 = f.Key1 and t.Key2 = f.Key2.....)
