Mysql將--secure-file-priv選項設置爲NULL

Question

我在Ubuntu中運行MySQL。運行特定的一組查詢時出現此錯誤。

MySQL服務器與--secure-文件私法選項運行，所以當我在我的MySQL服務器我/var/lib/mysql-files/做SELECT @@secure_file_priv;它不能執行該語句

。我想我需要做到這一點NULL。

這是查詢我運行：

LOAD DATA INFILE :file INTO TABLE test_files 
COLUMNS TERMINATED BY ',' ENCLOSED BY '\"' 
LINES TERMINATED BY '\n'; 

現在的問題是如何使這個NULL？

Answer 1

嘗試：

mysql> SELECT VERSION(); 
+-----------+ 
| VERSION() | 
+-----------+ 
| 5.7.12-0 | 
+-----------+ 
1 row in set (0.00 sec) 

mysql> SELECT @@GLOBAL.secure_file_priv; 
+---------------------------+ 
| @@GLOBAL.secure_file_priv | 
+---------------------------+ 
| /var/lib/mysql-files/  | 
+---------------------------+ 
1 row in set (0.00 sec) 

更改文件：/etc/mysql/my.cnf

[mysqld] 
. 
. 
. 
secure_file_priv=NULL 
. 
. 
. 

重啓MySQL。

mysql> SELECT @@GLOBAL.secure_file_priv; 
+---------------------------+ 
| @@GLOBAL.secure_file_priv | 
+---------------------------+ 
| NULL      | 
+---------------------------+ 
1 row in set (0.00 sec) 

UPDATE

mysql> SELECT @@GLOBAL.secure_file_priv; 
+---------------------------+ 
| @@GLOBAL.secure_file_priv | 
+---------------------------+ 
| /var/lib/mysql-files/  | 
+---------------------------+ 
1 row in set (0.00 sec)
