I am trying to export products to a csv file but get the permissions error below.

Is there anyway to run this code?
(I don't want to use EasyPopuate or PHPadmin)
I run the code below in TOOLS>SQL Patches

SELECT *
INTO OUTFILE 'downloads/result.csv'
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
FROM products, products_description;

Error message:-

1045 Access denied for user 'user_admin'@'localhost' (using password: YES)
in:
[SELECT * INTO OUTFILE 'downloads/result.csv' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM products,products_description;]
