select into outfile

persona版本：5.7.25.28

SELECT ... INTO

问题现象：

(apple) > select * INTO OUTFILE 'data.txt' FIELDS TERMINATED BY ',' from user;  
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

 my.cnf配置：

[mysqld]


secure_file_priv =/tmp

 导出表数据：

不管是在本地机器上执行，还是远程执行导出命令，都会导出到本地机器上:路径必须是/tmp/开头

select * from e into outfile "/tmp/data.txt" fields terminated by ',';

select...into outfile 的结果只包含了表数据，默认以 Tab 分隔，也可指定分隔符：

select * INTO OUTFILE '/tmp/data.txt' FIELDS TERMINATED BY ',' from user;

数据类似如下：

1,guolicheng,422802199909136854,1
2,yuguocong,4228021998069513652,2
