ORDER BY

Modifying the query so we add 'and profile_id sent a message'

I am not looking for profile_id where only staff3 sent a message
(there is no example of this with my inserts)

I do not understand this question. I think you might have added "not" incorrectly, so I am assuming you want the opposite of the previous question:
SELECT
        profile_id
FROM a_messages2
GROUP BY
        profile_id
HAVING sum(CASE WHEN sender <> 'staff3' THEN 1 ELSE 0 END) = 0
ORDER BY
        profile_id
;

This result:
| PROFILE_ID |
|------------|
|        abl |
|        big |
|        h1a |
|        swa |

Open in new window

from this query:
SELECT
        profile_id
FROM a_messages2
WHERE sender = profile_id OR sender = 'staff3'
GROUP BY
        profile_id
HAVING sum(CASE WHEN sender = 'staff3' THEN 1 ELSE 0 END) > 0
AND sum(CASE WHEN sender = profile_id THEN 1 ELSE 0 END) > 0
ORDER BY
        profile_id
;
