   SELECT SUM(count)=3 FROM ( SELECT COUNT() as count FROM mysql.tables_priv WHERE Table_priv='Select' and User='mysql.session' and Db='mysql' and Table_name='user' UNION ALL SELECT COUNT() as count FROM mysql.db WHERE Select_priv='Y' and User='mysql.session' and Db='performance_schema' UNION ALL SELECT COUNT(*) as count FROM mysql.user WHERE Super_priv='Y' and User='mysql.session') as user_priv;
