mysql启动时的初始执行文件的使用

可以在配置文件里指定mysql启动以后初始执行的SQL文件, 其语法是:

在[mysqld]或者[server]下指定:

init-file=D:/mysql-5.5.28-winx64/abc.sql, 后边为具体的sql文件值

注意下边两点就行了:

1. 确保你的mysqld 编译的时候没有加 --disable-grant-options 开关。

2. 确保init-file指定的脚本每行是一个具体的可以执行的语句。

为了示例:

abc.sql为:

use test;

begin;

create table if not exists t123(id int);

insert into t123 values(1);

insert into t123 values(2);

select * from t123;

-- drop table t123;

end;

启动完mysql以后,得到查询:

mysql> use test;  

Database changed

mysql> select * from t123;

+------+

| id |

+------+

| 1 |

| 2 |

+------+

2 rows in set (0.00 sec)


第二次启动以后,得到结果:

Welcome to the MySQL monitor. Commands end with ; or /g.

Your MySQL connection id is 2
