MySQL ERROR 1290 (HY000) --secure-file-priv option

Ubuntu 16.04 (EASY): Find out where you are allowed to write

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

Then, just write there

mysql> SELECT * FROM train INTO OUTFILE '/var/lib/mysql-files/test.csv' FIELDS TERMINATED BY ',';
Query OK, 992931 rows affected (1.65 sec)

mysql>

Mac OSX: Mysql installed via MAMP

Find out where you are allowed to write

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

NULL means you're screwed so you have to create the file "~/.my.cnf"

Enable read/write for MySQL installed via MAMP (on Mac):

  1. open "MAMP" use spotlight
  2. click "Stop Servers"

  3. edit ~/.my.cnf (using vi or your favorite editor) and add the following lines:

    $ vi ~/.my.cnf

[mysqld_safe]
[mysqld]
secure_file_priv="/Users/russian_spy/"
  1. click "Start Servers" (in MAMP window)

Now check if it works:

a. start mysql (default MAMP user is root, password is also root)

$ /Applications/MAMP/Library/bin/mysql -u root -p

b. in mysql look at the white-listed paths

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

c. Finally, test by exporting a table train into a CSV file

mysql> SELECT * FROM train INTO OUTFILE '/Users/russian_spy/test.csv' FIELDS TERMINATED BY ',';
Query OK, 992931 rows affected (1.65 sec)

mysql>

Replace "\" to "/" in your file path.

Like this:

INTO OUTFILE 'D:/MySql/mysqlTest.txt';

You cannot export data as it is configured in mysql config files. Open my.cnf config file and check.

Quote from MySQL doc

This variable is used to limit the effect of data import and export operations, such as those performed by the LOAD DATA and SELECT ... INTO OUTFILE statements and the LOAD_FILE() function. These operations are permitted only to users who have the FILE privilege.

secure_file_priv may be set as follows:

  • If empty, the variable has no effect.

  • If set to the name of a directory, the server limits import and export operations to work only with files in that directory. The directory must exist; the server will not create it.

  • If set to NULL, the server disables import and export operations. This value is permitted as of MySQL 5.7.6.

(An empty value is the default, or it can be explicitly specified in my.cnf as secure_file_priv="". A NULL value can be set with secure_file_priv=NULL.)

So, if you want to export data, then you need to comment this option and restart mysql server. Then you will be able to export.


  1. Edit the (/etc/my.cnf file for CentOS) or (my.ini file for Windows)
  2. Add secure-file-priv = "" line at the end
  3. Stop mysql service using systemctl stop mysqld
  4. Restart it using systemctl start mysqld

It will now allow you to import and export the data.
