Recently, I deleted a user account in MySQL assigned to my former boss. Then, some database functions like deleting records from tables he made weren't working, giving the following error: #1449 - There is no '*username*'@'localhost' registered Now, I added a new user with the same name (and diff. password) and it works fine with no errors. But, is there way to resolve this without an placeholder user account? mysql mysql remove definer share|improve this question asked Jul 19 '12 at 17:47 Robert Dundon 9028 How did you delete his user?

If any other the reported DEFINERs no longer exist or are invalid, you can make root@localhost inherit them.
