如何修改mysql autocommit

MySQLautocommit（自提交）默认启其mysql性能定影响举例说插入1000条数据mysqlcommit1000我autocommit关闭掉通程序控制要commit

1,我通set设置autocommit

查看复制打印?

mysql>set global init_connect="set autocommit=0"//提示用权限更高财户设置

ERROR 1227 (42000): Access deniedyou 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//查看autocommit设置

+--------------+

| @@autocommit |

+--------------+

| 0 |

+--------------+

1 row in set (0.00 sec)

2,我修改mysql配置文件my.cnf关闭autocommit

查看复制打印?

[mysqld]

init_connect='SET autocommit=0' //mysqld面加些内容

用第二种关点要注意连接mysql用户权限能于启mysql用户权限init_connect='SET autocommit=0'根本启作用报任何错误汗先看实例

mysqlbug呢我网找找面问题真部内容：

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.

面点说清楚If a user has SUPER privilege, init_connect will not execute用户更高级权限init_connect根本执行
