Username in MySQL with regexp

Hello list, iam using FreeRADIUS-1.0.5 with MySQL-Backend. Now i want a username check with an regexp operator (=~), so that i can match usernames (+1234567(0-9)) against a regexp of "^\+^1234567" and dont have the need of creating 10 users which have all the same reply attributes. The Auth-Type of these usernames is always "Accept". How can i accomplish this? The username itself in the MySQL table doesnt has a check row.. Thanks for any help!
