connectby
hi
I have menu table:
id | integer | not null default
nextval('public.menu_id_seq'::text)
parent_id | integer |
description | text |
I do select:
test=> SELECT * FROM connectby('menu','id','parent_id','2',0,'~')
t(id integer, parent_id integer, level int, branch text);
id | parent_id | level | branch
----+-----------+-------+-------------
2 | | 0 | 2
4 | 2 | 1 | 2~4
7 | 4 | 2 | 2~4~7
10 | 7 | 3 | 2~4~7~10
16 | 10 | 4 | 2~4~7~10~16
9 | 4 | 2 | 2~4~9
How am I able to select description file from menu table,
not only id, parent_id, level, branch fields?

Try a join with the original table:
SELECT t.*, description FROM connectby('menu','id','parent_id','2',0,'~')
AS t(id integer, parent_id integer, level int, branch text), menu
WHERE t.id = menu.id

You need to upgrade. Either install 7.3.4 or wait a few weeks and
install 7.4 when it is released.

For recent versions of PostgreSQL, go into the contrib/tablefunc directory and see the readme file
for how to install. I downloaded PostgreSQL 7.2.3 and there was no contrib/tablefunc directory.
You'll have to upgrade.
