ERROR 1227 (42000): Access denied; you need (at least one of) the SUPER privilege(s) for this operation
mysql> set autocommit=0;
Query OK, 0 rows affected (0.00 sec)
mysql> select @@autocommit;
+--------------+
| @@autocommit |
+--------------+
| 0 |
+--------------+
1 row in set (0.00 sec)
2,我们可以修改mysql的配置文件my.cnf来关闭autocommit
查看复制打印?
- [mysqld]
- init_connect=‘SET autocommit=0‘
用第二种方法关,有一点要注意,连接mysql用户的权限不能大于启动mysql的用户的权限,不然init_connect=‘SET autocommit=0‘根本不会启作用,也不会报任何错误,汗一个先。看以下实例
查看复制打印?
- zhangy@ubuntu:~$ mysql -umysql
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is 1
- Server version: 5.5.2-m2-log Source distribution
-
- Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
-
- mysql> select @@autocommit;
- +--------------+
- | @@autocommit |
- +--------------+
- | 0 |
- +--------------+
- 1 row in set (0.00 sec)
-
- mysql> Ctrl-C -- exit!
- Aborted
- zhangy@ubuntu:~$ mysql -uroot
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is 2
- Server version: 5.5.2-m2-log Source distribution

这个会不会是mysql的bug呢?我在网上找了找这方面的问题,还真有。部分内容如下:
If a user has SUPER privilege, init_connect will not execute
(otherwise if init_connect will a wrong query no one can connect to server).
Note, if init_connect is a wrong query, the connection is closing without any errors
and next command will clause ‘lost connection‘ error.
里面有一点说的很清楚If a user has SUPER privilege, init_connect will not execute,如果用户有更高级的权限,init_connect根本不会执行。
