I have a guestbook, with messages stored in a table. There is a 'hits' field for each message. How do I run a query that will count the total number of hits?
SELECT name, COUNT(hits) FROM guestbook_message WHERE name='".$req_user_info['username']."' GROUP BY name";
This returns the amount of messages that the user has posted, where there is a value in the 'hits' field. But not the total amount of hits.
If there are 3 messages, with 3 hits each, it should return "9 hits". But the query I posted above would return "3".
Many thanks.

I think you're after SUM
SELECT name, SUM(hits) FROM guestbook_message WHERE name='".$req_user_info['username']."' GROUP BY name";
