MySQL批处理SQL语句

MySQL 支持批处理的模式运行一批SQL语句，以下的样例就是实验MySQL怎样在windows下批处理运行SQL语句。

create table test(id int,name varchar(20));
insert into test values(1,'watson');

batchfile.txt里包括以下的一些SQL 语句，此文件放在windows系统的c:/batchmysql/batchfile.txt

insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;
insert into test select * from test;

在cddl数据库里进行批运行上面的语句例如以下：
mysql -uroot -p -D cddl < c:/batchmysql/batchfile.txt

以下是把批处理里含有查询的信息，输出保存到一个文件中：

此时的batchfile2.txt里含有query的信息(以下的3条SQL语句)，以下的mysql0716.out就记录了select * from test limit 200;查询语句的结果集。
select * from test limit 200;
insert into test select * from test;
insert into test select * from test;

You can catch the output in a file for further processing:
mysql -uroot -p -D cddl < c:/batchmysql/batchfile2.txt >c:/batchmysql/mysql0716.out
