Grant privileges on several tables with specific prefix

Question

I\'m using the table prefix method for having several clients use the same database. The number of tables created per client will be ~55. Instead of doing all of the grant

Answer 1

The following

GRANT SELECT , INSERT , UPDATE , DELETE ON ``database.prefix\_%``. * TO 'username'@'localhost'

works fine (tested with MySQL 5.6.12 on Windows)
