向数据表导入数据 
Load Data InFile 'C:/Data.txt' Into Table `TableTest` 

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
