MySQL批處理SQL語句

MySQL批處理SQL語句

MySQL 支援批處理的模式執行一批SQL語句，下面的例子就是實驗MySQL如何在windows下批處理執行SQL語句。
 
create table test(id int,name varchar(20));
 insert into test values(1,'watson');
 
 
batchfile.txt裡包含下面的一些SQL 陳述式，此檔案放在windows系統的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資料庫裡進行批執行上面的語句如下：
 mysql -uroot -p -D cddl < c:/batchmysql/batchfile.txt
 
 
下面是把批處理裡含有查詢的資訊，輸出儲存到一個檔案裡：
 
此時的batchfile2.txt裡含有query的資訊(下面的3條SQL語句)，下面的mysql0716.out就記錄了select * from test limit 200;查詢語句的結果集。
 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
