Subject: Merging rows into one result?

Message-ID: <20060311173133.1358a018@io.solnet> (raw)
Is it possible to use SQL to merge data into one result?
A theorethical example to explain:
tbl_test (
id integer,
information varchar(25))
id | information
---+--------------
1 | Yo
2 | Go away
1 | Stay put
3 | Greetings
Please note id is not unique and not a primary key.
and I wonder if there is any functions to "merge" data (sort of
concat'ing).
A normal: select information from tbl_test where id=1
would result in the rows
Yo
Stay put
I would like a single row result in the format of:
Yo Stay put
Any ideas on this?
Best regards
Jesper K. Pedersen
