Dear Richard Ekblom,
I think Mr. Adrian Klaver gave you the solution. Mine is the similar solution
SELECT message.id,topic.topic,message.message
FROM topics, messages
WHERE message.topic=topic.id order by message.id;
After executing this query you will get the following:
id | top

Dear Richard Ekblom,
I think Mr. Adrian Klaver gave you the solution. Mine is the similar
solution
SELECT message.id,topic.topic,message.me
if you want topics listed which don't yet have messages try
select t.id, t.topic, m.id, m.message from topics t left join messages m on
m.topic = t.id;
