Mostrar tablas por motor en MySQL

Question

¿Cómo mostraría todas las tablas en MySQL con un motor dado, por ejemplo, InnoDB, MyISAM, FEDERATED?

Answer 1

Otros ejemplos aquí.

Todas las tablas por motor (excepto las tablas del sistema):

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'');

Todas las tablas excepto el motor (excepto las tablas del sistema):

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'');

Answer 2

Si alguno tiene un problema y quiere ver en qué DB están las tablas con motor específico

SELECT 
        (SELECT group_concat(TABLE_NAME) 
            FROM information_schema.TABLES
            WHERE TABLE_SCHEMA = ''database1'' 
            AND engine = ''MyIsam''
        ) as database1, 
        (SELECT group_concat(TABLE_NAME) 
            FROM information_schema.TABLES
            WHERE TABLE_SCHEMA = ''database2'' 
            AND engine = ''MyIsam''
        ) as database2,
        (SELECT group_concat(TABLE_NAME) 
            FROM information_schema.TABLES
            WHERE TABLE_SCHEMA = ''database3'' 
            AND engine = ''MyIsam''
         ) as database3;

Saludos.

Answer 3

Si quieres los resultados de una base de datos única

SELECT TABLE_NAME FROM information_schema.TABLES
    WHERE TABLE_SCHEMA = ''dbname'' AND engine = ''InnoDB'';

Answer 4

Utilice la tabla INFORMATION_SCHEMA.TABLES :

SELECT table_name FROM INFORMATION_SCHEMA.TABLES
  WHERE engine = ''InnoDB''
