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


You want to export a MySQL database table as a csv with something like:

but you get the error that MySQL cannot execute this command.


Find out the location that MySQL can use to export files by running the following:

and then use the path to change the outfile path (ie /var/lib/mysql-files/table_name.csv).

Exporting query results from MySQL


You would like to export some query results from MySQL into a format that can be imported in LibreOffice, OpenOffice or Excel.


Try first with the default export options, as by doing a google search, there are a lot of different options for specifying field delimeters, lines terminated, etc.
So by not specifying any additional options the export is a tab delimited, linefeed-terminated file which should work in most of the programs.
So in order to do that you would need a folder in the MySQL server that should have write access. Usually /tmp should do. Then you can build your query and at the end add the INTO OUTFILE ‘/path’, like:

You can use any file ending but usually by specifying .csv the program that you will try to open will understand it.

Comparing data from two big MySQL tables

You have two big tables in MySQL (>640K records), that maybe differ in the number of fields, but you want to make sure that the data in the common fields in both tables are the same.


  1. Use mysql to export the data from the first table in a csv file, selecting only the common fields.
    We use the /tmp folder on the server to make sure we have the right permissions to create the file:
  2. If the tables are in different databases remember to switch db:

    Export the second table in the second file:
  3. now use the diff. You can use any of the following options:
    • diff -q first_table.txt second_table.txt
    • diff first_table.txt second_table.txt > diff.txt
