修改mysql 表引擎类型错误

Posted 2020-06-11

mysql引擎默认类型为MyISAM,

mysql>show engines;

事务隔离机制为：READ-COMMITTED(/etc/my.cnf查看)

默认建表如果不指定引擎类型，自动为MyISAM。此时想更改表为InnoDB类型。用户登陆到mysql客户端执行：
mysql>alter table ATT engine = InnoDB;

则报错：
ERROR 1598 (HY000): Binary logging not possible. Message: Transaction level ‘READ-COMMITTED‘ in InnoDB is not safe for binlog mode ‘STATEMENT‘。

解决办法：
运行该命令即可：SET SESSION TRANSACTION ISOLATION LEVEL REPEATABLE READ;

上面方法治标不治本！
这种方式强行修改了表的引擎类型，会导致表插入数据失败，依然提示错误：
Binary logging not possible. Message: Transaction level ‘READ-COMMITTED‘ in InnoDB is not safe for binlog mode ‘STATEMENT‘.
解决办法：/etc/my.cnf添加参数：
binlog_format = ROW
innodb_locks_unsafe_for_binlog = 1
