mysql批量修改存储引擎和字符集

生成sql格式(将qdm723412313_db改为你的数据库名称即可):

SELECT
    concat( 'alter table ', table_name, ' engine=InnoDB CHARSET=utf8mb4; ' ) 
FROM
    information_schema.TABLES t 
WHERE
    table_schema = 'qdm723412313_db' 
    AND table_type = 'base table';

生成数据如下：

alter table cmf_user engine=InnoDB CHARSET=utf8mb4; 
alter table think_ad engine=InnoDB CHARSET=utf8mb4; 
alter table think_ad_type engine=InnoDB CHARSET=utf8mb4; 
alter table think_admin engine=InnoDB CHARSET=utf8mb4; 
alter table think_admin_log engine=InnoDB CHARSET=utf8mb4; 
alter table think_answer_question engine=InnoDB CHARSET=utf8mb4; 
alter table think_article engine=InnoDB CHARSET=utf8mb4; 
alter table think_auth_group engine=InnoDB CHARSET=utf8mb4;

然后再复制执行即可
