Wenn ein Problem haben und in dem sehen will DB-Tabellen mit spezifischem Motor ist

SELECT 
     (SELECT group_concat(TABLE_NAME) 
      FROM information_schema.TABLES

Alle Tabellen außer dem Motor (außer Systemtabellen):

SELECT TABLE_SCHEMA as DbName ,TABLE_NAME as TableName ,ENGINE as Engine 
FROM information_schema.TABLES 
WHERE ENGINE != 'MyISAM' -- or InnoDB or whatever 
AND TABLE_SCHEMA NOT IN('mysql','information_schema','performance_schema');
