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。
