Just create a Unique index. For example if the table is named Tbl then (for example) Create Unique Index IX_Tbl1 on Tbl (user_id, job_id); This will allow user_id or job_id to be duplicated in the table, but no combination of user_id and job_id can be repeated. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2-rc1-SuSE (GNU/Linux) iD8DBQE/HfzTjeziQOokQnARAtYmAJ9j7rWWvIbEPkLKcL1oDbdveJJELQCfWkKE e+BFvxSllsIqZJ5Q3nCeXcg= =zPh7 -----END PGP SIGNATURE----- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
