recursion - Recursive query in PostgreSQL. SELECT * -


i have recursive query retrieve children of given person

with recursive recursetree(id, parent_id) (     select id, parent_id tree parent_id = 0   union     select t.id, t.parent_id     tree t     join recursetree rt on rt.id = t.parent_id   ) select * recursetree;

as can see, i'm specifying list of columns retrieved. want use select * (i have many columns in real table, , can changed in future). there way columns without defining each column individually?

you don't need specify columns in with part. if leave out, column names determined first query in union:

with recursive recursetree (     select * tree parent_id = 0   union     select t.*     tree t     join recursetree rt on rt.id = t.parent_id ) select *  recursetree;
