MySQL批处理SQL语句

MySQL 支持批处理的模式执行一批SQL语句，下面的例子就是实验MySQL如何在windows下批处理执行SQL语句。

MySQL 支持批处理的模式执行一批SQL语句，下面的例子就是实验MySQL如何在windows下批处理执行SQL语句。

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


batchfile.txt里包含下面的一些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数据库里进行批执行上面的语句如下：
mysql -uroot -p -D cddl < c:/batchmysql/batchfile.txt


下面是把批处理里含有查询的信息，输出保存到一个文件里：

此时的batchfile2.txt里含有query的信息(下面的3条SQL语句)，，下面的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
