Load Data InFile 的用法

Load Data InFile是用于批量向数据表中导入记录。
首先创建一个表
Use Test;
Create Table TableTest(
`ID` mediumint(8) default '0',
`Name` varchar(100) default ''
) TYPE=MyISAM;

向数据表导入数据
Load Data InFile 'C:/Data.txt' Into Table `TableTest`文章源自很文博客https://www.hinwi.com/很文博客-https://www.hinwi.com/52477.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”文章源自很文博客https://www.hinwi.com/很文博客-https://www.hinwi.com/52477.html

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。文章源自很文博客https://www.hinwi.com/很文博客-https://www.hinwi.com/52477.html
