Hi I'm attempting to do some partitioning in a database and am wondering if I can use the data being inserted to insert into new schema. I have the following in the public schema: create table test (id serial, note varchar not null, schema varchar not null) then create a schema: create schema "1-2-3"; create schema "4-5-6"; and 2 tables: create table "1-2-3".test () inherits public.test; create table "1-2-3".test () inherits public.test; I then want something similar to: create or replace function test() returns trigger as $$ begin insert into NEW.schema.test values (NEW.*); return null; end; $$ language plpgsql; create trigger test_insert before insert on test for each row execute procedure test(); so that: insert into test (schema, note) values ('1-2-3', 'some note data'); would result in the data going into the table "1-2-3".test This doesn't work as expected as the "NEW.schema.test" isn't substituted with "1-2-3". I don't think I can use an if statement as I will have an unknown number of schemas. Thanks Jake
