you can simply use BCP command, in which case you have to enable the xp_cmdshell if you are using SQL mangement studio.

Here is an example

<pre><code>DECLARE @bcpCommand varchar(2000)

SET @bcpCommand = 'bcp "SELECT * FROM users" queryout "c:\dump.csv" -U USERNAME -P PASSWORD -c'

EXEC master..xp_cmdshell @bcpCommand
</code></pre>

Note that the csv file is located in the server where the database is hosted.

It appears that MySQL does not <a href="http://bugs.mysql.com/bug.php?id=34992" rel="nofollow noreferrer">natively support</a> the ability to include column headers in an export. A simple google search returned this <a href="http://www.youdidwhatwithtsql.com/add-column-headers-mysql-outfile/911" rel="nofollow noreferrer">article</a> which uses stream edit to add columns to an export file.

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

<pre><code>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&gt;39 AND a.is_active=1
ORDER BY last_name
</code></pre>

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

You can also check the <code>SELECT ... INTO</code> syntax <a href="http://dev.mysql.com/doc/refman/5.6/en/select-into.html" rel="nofollow">here</a>.

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

<pre><code>mysql &gt; 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&gt;39 AND a.is_active=1 ORDER BY last_name
</code></pre>

How would I do this?
