1. 运行环境
Win10 + MySQL5.7.25
2. 问题描述
在到处数据时,报错:ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement。
mysql> SELECT *
-> FROM courses
-> INTO OUTFILE "D:\\DatabaseSoftware\\output\\courses4.txt";
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
3. 问题原因
查看官方文档,secure_file_priv参数用于限制LOAD DATA, SELECT …OUTFILE, LOAD_FILE()传到哪个指定目录。
- secure_file_priv 为 NULL 时,表示限制mysqld不允许导入或导出。
- secure_file_priv 为 /tmp 时,表示限制mysqld只能在/tmp目录中执行导入导出,其他目录不能执行。
- secure_file_priv 没有值时,表示不限制mysqld在任意目录的导入导出。
我们可以查看secure_file_priv 的值,默认为NULL,表示限制不能导入导出。
mysql> SHOW GLOBAL VARIABLES LIKE "%secure_file_priv%";
+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| secure_file_priv | NULL |
+------------------+-------+
1 row in set, 1 warning (0.00 sec)
4. 解决办法
因为secure_file_priv参数是只读参数,不能使用set global命令修改。
mysql> SET GLOBAL secure_file_priv="";
ERROR 1238 (HY000): Variable 'secure_file_priv' is a read only variable
正确办法:修改my.ini配置文件
- 在my.ini配置文件中加入
secure_file_priv = ""
保存退出,这个时候要稍微留意一下编码问题,如果后面发现无法启动mysql,可以参考我这篇文章【错误】Win10中MySQL5.7 net start mysql服务正在启动或停止中,请稍候片刻后再试一次
2. 退出MySQL,关闭MySQL服务
mysql> quit
Bye
D:\DatabaseSoftware\MySQL5.7.25\bin>net stop mysql
MySQL 服务正在停止.
MySQL 服务已成功停止。
- 重启MySQL服务
D:\DatabaseSoftware\MySQL5.7.25\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
D:\DatabaseSoftware\MySQL5.7.25\bin>mysql -u root -p

+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| secure_file_priv | |
+------------------+-------+
1 row in set, 1 warning (0.00 sec)
发现已经成功修改secure_file_priv为空。
4. 导出成功
mysql> use my_db;
mysql> SELECT *
-> FROM courses
-> INTO OUTFILE "D:\\DatabaseSoftware\\output\\courses4.txt";
Query OK, 10 rows affected (0.01 sec)
5. 注意事项
注意指定路径的时候一定要写对:
mysql> SELECT *
-> FROM courses
-> INTO OUTFILE "D:\DatabaseSoftware\output\courses5.txt"
-> ;
Query OK, 10 rows affected (0.00 sec)
这样写显示导出成功了,但是在目录下并没有发现courses5.txt文件。
所以,路径要写为一下两种形式:
形式一:
mysql> SELECT *
-> FROM courses
-> INTO OUTFILE "D:\\DatabaseSoftware\\output\\courses5.txt";
Query OK, 10 rows affected (0.00 sec)
形式二:
mysql> SELECT *
-> FROM courses
-> INTO OUTFILE "D:/DatabaseSoftware/output/courses6.txt";
Query OK, 10 rows affected (0.00 sec)
