MySQL5 Problem while creating new user – SQL Error (1133): Can’t find any matching row in the user table
When we use GUI tools like HeidiSQL with MySQL Windows binaries – setup from MySQL.com might be creating issues like these. Because recently faced errors #1364 and #1133 both became visible while I did clean install of MySQL by downloading Windows Installer for MySQL 5.5.8 from MySQL.com and not while using it with MySQL as part of some WAMP package.
