Well, that's why I'm saying your implementation is not what MySQL people expect. The date data type is representation-agnostic itself, and AddDate, DateDiff, etc work with the date data type (at least in MySQL). What you need is functions to covert from internal date representation to Iranian calendar string, and vice versa. You don't need (and should not) implement all date functions again. --behdad http://behdad.org/ _______________________________________________ PersianComputing mailing list PersianComputing@lists.sharif.edu http://lists.sharif.edu/mailman/listinfo/persiancomputing
