load data infile into table 的使用例子

原文来自：http://blog.sina.com.cn/s/blog_605f5b4f0100zoqb.html

常用如下：

Load Data InFile 'C:/Data.txt' Into Table `TableTest` Lines Terminated By '\r\n';
这个语句，字段默认用制表符隔开，每条记录用换行符隔开，在Windows下换行符为“\r\n”

C:/Data.txt 文件内容如下面两行：
1 A
2 B
“1”和“A”之间有一个制表符
这样就导进两条记录了。



自定义语法
Load Data InFile 'C:/Data.txt' Into Table `TableTest` Fields Terminated By ',' Enclosed By '"' Escaped By '"' Lines Terminated By '\r\n';

Fields Terminated By ',' Enclosed By '"' Escaped By '"'
表示每个字段用逗号分开，内容包含在双引号内

Lines Terminated By '\r\n';
表示每条数据用换行符分开


和 Load Data InFile 相反的是
Select * From `TableTest` Into OutFile 'C:/Data_OutFile.txt';
把表的数据导出

 

我们的示例文本文件：
"我爱你","20","相貌平常，经常耍流氓！哈哈"
"李奎","21","相貌平常，经常耍流氓！哈哈"
"王二米","20","相貌平常，经常耍流氓！哈哈"
"老三","24","很强"

"老高","10","学习很好"
"斜三","60","眼睛斜了"
"中华之子","100","威武的不行了"
"大米","63","我爱吃"
"苹果","15","好吃"
我们的示例表结构：

 CREATE TABLE t0 (

id bigint(20) unsigned NOT NULL auto_increment,

name char(20) NOT NULL,

age tinyint(3) unsigned NOT NULL,

description text NOT NULL,

PRIMARY KEY (id),

UNIQUE KEY idx_name (name)

) ENGINE=MyISAM DEFAULT CHARSET=utf8 

 

mysql> load data infile '/tmp/t0.txt' ignore into table t0 character set gbk fields terminated by ',' enclosed by '"' lines terminated by '\n' (name,age,description);

 

Query OK, 19 rows affected (0.01 sec)
Records: 19 Deleted: 0 Skipped: 0 Warnings: 0

mysql> select * from t0;
+----+----------+-----+----------------------------+
| id | name     | age | description                |
