mysql 初始执行文件的使用介绍_MySQL

bitsCN.com

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：
