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>
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
