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：

name="code" class="sql">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：
