Bash中使用MySQL导入导出CSV格式数据[转]

时间:2021-07-01 10:21:17 帮助过:14人阅读

* from test_info into outfile /tmp/test.csv fields terminated by , optionally enclosed by " escaped by " lines terminated by \r\n;

 

MySQL中导入CSV格式数据的SQL语句样本如下:

 
load data infile /tmp/test.csv 
into table test_info  
fields terminated by ,  optionally enclosed by " escaped by " 
lines terminated by \r\n; 

 

里面最关键的部分就是格式参数

fields terminated by , optionally enclosed by " escaped by " 
lines terminated by \r\n 

 

这个参数是根据RFC4180文档设置的,该文档全称Common Format and MIME Type for Comma-Separated Values (CSV) Files,其中详细描述了CSV格式,其要点包括:

(1)字段之间以逗号分隔,数据行之间以\r\n分隔;

(2)字符串以半角双引号包围,字符串本身的双引号用两个双引号表示。
