存储过程批量修改MySql引擎

1、下面这两个结合可以用到生产环境。
1）、修改整个库，调用第三个SP。
DELIMITER $$ DROP PROCEDURE IF EXISTS `t_girl`.`sp_alter_db_engine`$$ CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_alter_db_engine`( IN f_db_name varchar(255), IN f_engine_name varchar(255)) BEGIN -- Get the total number of tables. declare cnt1 int default 0; declare i int; set i = 0; select count(1) from information_schema.tables where table_schema = f_db_name into cnt1; while i < cnt1 do set @stmt = concat('select @tbname:=table_name from information_schema.tables where table_schema=''',f_db_name,''' order by table_name desc limit ',i,',1 into @tbname'); prepare s1 from @stmt; execute s1; deallocate prepare s1; set @stmt = ''; set @tbname = concat(f_db_name,'.',@tbname); call sp_alter_table_engine(@tbname,f_engine_name); set i = i + 1; end while; END$$ DELIMITER ;
2）、修改单个表
DELIMITER $$ DROP PROCEDURE IF EXISTS `t_girl`.`sp_alter_table_engine`$$ CREATE DEFINER=`root`@`%` PROCEDURE `sp_alter_table_engine`( IN f_tb_name varchar(255),IN f_engine_name varchar(20)) BEGIN set @stmt = concat('alter table ',f_tb_name,' engine=',f_engine_name); prepare s1 from @stmt; execute s1; deallocate prepare s1; set @stmt = ''; END$$ DELIMITER ; 
3、测试结果：
[SQL] call sp_alter_db_engine('baigan_cs','innodb');
