you would have to use 2 separate queries.
One query that pulls all the ID's from tableA that aren't in tableB and another query that pulls all the ID's from tableB that aren't in tableA Code:
// Get all the ID's from tableA that aren't in tableB SELECT [ID] FROM tableA WHERE tableA.ID NOT IN (SELECT [ID] FROM tableB) // Get all the ID's from tableB that aren't in tableA SELECT [ID] FROM tableB WHERE tableB.ID NOT IN (SELECT [ID] FROM tableA) then you could just combine the ID's and display them in numerical order.

Select TableA.Column1, TableA. Column2, TableB.Column2
FROM TableA INNER JOIN TableB ON TableA.Column1 = TableB.Column1; I believe that this is what you are after S-
