I have the following SQl query I'm running against two tables in an Access 2007 database:

SELECT ContactPhone.Item_ID, ContactPhone.Last_Name, ContactPhone.First_Name, ContactPhone.Work_Phone, ContactPhone.[1st_Choice], ContactPhone.[2nd_Choice], ContactPhone.[3rd_Choice], ContactPhone.Comments
FROM ContactPhone LEFT JOIN onlyDCS ON ContactPhone.Work_Phone=onlyDCS.Work_Phone
WHERE (((onlyDCS.Work_Phone) Is Null));


I want to just use a substring compare of the last  four character of the "Work_Phone" from both tables.

example of the Work_Phone  data

555-1234

just need to compare

1234

Thanks!!

you can only do this in the sql view of the query

select * from ContactPhone
where  right([ContactPhone ].[Work_Phone],4)=right([onlyDCS].[Work_Phone],4)
