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
