操做流程：mysql

$ mysql -uroot -p
mysql> use foo;
mysql> select * from userinfo into outfile '/var/lib/mysql-files/uc3dp_v1.0_userinfo.txt' fields terminated by ', ' lines terminated by '\n';

注意：上面命令中的路径不能够随意乱指定，如改为/tmp/uc3dp_v1.0_userinfo.txt就会报错： sql

ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

缘由是mysql设置了安全措施，必须将文件输出到其指定目录才行。能够经过以下命令查看系统设置的默认目录：安全

mysql> SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-----------------------+
| Variable_name    | Value                 |
+------------------+-----------------------+
| secure_file_priv | /var/lib/mysql-files/ |
+------------------+-----------------------+
1 row in set (0.01 sec)
