Hi

Can someone please tell me how to delete duplicate records from my DB, where I have about 65502 records. I have a auto-incremend "id" field, then I have a file_letter field (which holds info like A, B, C - Z), and then I have a file_no field. Basically, the file_letter and file_no fields make a unique pair, thus there can be more than one "file_no = '23' (for ex. file_letter = A, file_no = 32 / file_letter=B, file_no = 32, etc etc)

How do I delete duplicate records using these two fields as a unique pair? I'm running MySQL 5.0.15-max-log.
