Como borrar "solo" las tablas de un MySQL

SET FOREIGN_KEY_CHECKS = 0;
SET @tables = NULL;
SELECT GROUP_CONCAT(table_schema, '.', table_name) INTO @tables
  FROM information_schema.tables
  WHERE table_schema = 'hippo'; -- specify DB name here.

SET @tables = CONCAT('DROP TABLE ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;
