1.进入mysql查看secure_file_prive的值
$mysql -u root -p
mysql>SHOW VARIABLES LIKE "secure_file_priv";
secure_file_prive=null --限制mysqld 不允许导入导出
secure_file_priv=/tmp/ --限制mysqld的导入导出只能发生在/tmp/目录下
secure_file_priv=' '--不对mysqld的导入导出做限制
2.更改secure_file_pri的值
/usr/local/mysql/support-files中的my-f配置文件,就把它复制到/private/etc中,重命名为“f”,并加入secure_file_priv='',重启mysql服务器即可。
3.导入csv文件
-- sql导入csv文件
load data local infile '/Users/jojo/dumps/train.csv' --文件目录
into table new_table -- 这里导入csv会出错,具体解决方法见"问题解决"
fields terminated by','optionally enclosed by '"' escaped by '"'
-- 字段之间以逗号分隔,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
lines terminated by'\r\n' -- 数据行之间以\r\n分隔
4.导出csv文件
select * from table_name
into outfile 'C:/ProgramData/MySQL/MySQL Server5.7/xx.csv'
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '/n'
