Hi,
I have a table t_categories(nr serial, nr_up integer,name text, ....)
nr_up is a number of category which is one point up to the inserted
category.
and second table t_category_search(nr_ins integer,nr_up)
I try to write Pl/pgsql function using recurrence ....
It should start on insert to t_categories ... (trigger), and create new
rows in t_category_search :
for_example : if there is the structure c1 -----> c2 ----> c3
and I want to create c4 which should be located directly under c3, so I
want to get in t_category_search
(0,c4), #0 is the number of max top abstraction category
(c4,c4)
(c4,c1)
(c4,c2)
(c4,c3)
It is possible to use recurrence in PL/pgsql to make such trigger or
there is somo other way to make it on PL/pgsql
Thanks in advance
Adam
