Finding and constraining



     I have a join table 'contact_letter' with fk's letter_id and contact_id.


     trying to write a script to find all records in the contact_letter table that have a letter_id of x or y (user sets both when prompted) with duplicate contact_ids...

     tried a number of combinations not having any success - it's got to be easy, just can't get it

     all help appreciated
