对mysql修改库里面所有的引擎mysaim 为 innodb
1.查看当前数据引擎的命令: show engines; 2. USE `[DBNAME]`; SELECT GROUP_CONCAT(CONCAT( 'ALTER TABLE ' ,TABLE_NAME ,' ENGINE=InnoDB; ') SEPARATOR '' ) FROM information_schema.TABLES AS t WHERE TABLE_SCHEMA = '[DBNAME]' AND TABLE_TYPE = 'BASE TABLE'; 将其中的红色部分替换为你所使用的数据库 执行后其实生成的是查询命令,然后copy生产的命令,执行SQL 即可: ALTER TABLE info_aaaa ENGINE=InnoDB; ALTER TABLE info_data_bbb ENGINE=InnoDB; ALTER TABLE info_data_ccc ENGINE=InnoDB; ALTER TABLE info_data_ddd ENGINE=InnoDB; ALTER TABLE info_data_eee ENGINE=InnoDB; ALTER TABLE info_data_fffENGINE=InnoDB; 再次查看数据表的数据引擎已经更改了:show table status from [DBNAME];
