Hello
I have frequently encountered the need of combining two tables into one.
First, please take a look at the following table setups...
CREATE TABLE topics (
id SERIAL PRIMARY KEY,
topic TEXT NOT NULL
);
CREATE TABLE messages (
id SERIAL PRIMARY KEY,
topic INTEGER REFERENCES

Dear Richard Ekblom,
I think Mr. Adrian Klaver gave you the solution. Mine is the similar
solution
SELECT message.id,topic.topic,message.message
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;
