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;  <p>Database changed  </p><p>mysql> select * from t123;  </p><p>+------+  </p><p>| id   |  </p><p>+------+  </p><p>|    1 |  </p><p>|    2 |  </p><p>+------+  </p><p>2 rows in set (0.00 sec)  </p><p></p>
Copy after login

 

 

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

mysql> use test;  

Database changed  

mysql> select * from t123;  

+------+

+------+  

|    1 |  

|    2 |  

|    1 |  

|    2 |  

+------+  

4 rows in set (0.00 sec)
