Question

I have the following SQL command that I need to save as a csv file with column headers:

mysql > SELECT  a.last_name, a.first_name, username, is_active, graduation
        FROM auth_user a
        INNER JOIN 
            userprofile_userprofile u
            ON a.id = u.user_id
        WHERE a.id>39 AND a.is_active=1 ORDER BY last_name

How would I do this?

Answer 1

If I’m not commiting any syntactical mistake this should work:

SELECT 'LastName', 'FirstName', 'Username', 'IsActive', 'Graduation'
UNION ALL
SELECT a.last_name, a.first_name, username, is_active, graduation
INTO OUTFILE 'yourFile.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
FROM auth_user a
INNER JOIN  userprofile_userprofile u
ON a.id = u.user_id
WHERE a.id>39 AND a.is_active=1
ORDER BY last_name

MySQL won’t allow you to add column headers so you can hard code them in a union.

You can also check the SELECT ... INTO syntax here.
