MySQL中导出CSV格式数据的SQL语句样本如下：
select * 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。
