本文将详细介绍MySQL如何导入csv格式数据文件并提供详细解决方案,需要了解的朋友可以参考下

给自己做备份的,高手们请忽略。
数据太大,用数据库客户端软件直接导入非常卡,还是直接执行SQL吧。
1、指定文件路径。
2、字段之间以逗号分隔,数据行之间以\r\n分隔(我这里文件是以\n分隔的)。
3、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。

Sql代码
代码如下:
load data infile 'D:\\top-1m.csv'
into table `site`
fields terminated by ',' optionally enclosed by '"' escaped by '"'
lines terminated by '\n';

顺带也备份个导出吧。
Sql代码
代码如下:
select * from `site`
into outfile 'D:\\top-1m.csv'
fields terminated by ',' optionally enclosed by '"' escaped by '"'
lines terminated by '\n';
