Delete query

I would like to delete codes from 1 table that do not exist in another but not sure how to do that.

Table1 UploadforcedMatches (delete [vrr_vehicleid]) from this table
Table2 TblExportVinstems where vrr_vehicleID does not exist in here

Pete's got the SQL you need, but an easy way to do this through the query designer is to create a SELECT query that pulls the records that you want to delete, and then right-click the query builder window --> query type -->Delete Query

You've almost written the sql in prose there!!

DELETE FROM UploadforcedMatches
 WHERE NOT EXISTS
    (SELECT vrr_vehicleID                                        
   FROM TblExportVinstems
   WHERE TblExportVinstems .InvoiceID = UploadforcedMatches .vrr_vehicleID);
 
Backup before testing.
