Well, I experimented a lot but didn't come to any useful result.
Actually I'm working on table partitioning as described at
http://www.postgresql.org/docs/8.3/static/ddl-partitioning.html , and
I wanted to write a trigger that would insert the data in the correct
table, and so I got the same problem with plpsql's NEW.* not usable in
a dynamically created query to be run by EXECUTE:
CREATE OR REPLACE FUNCTION part_test() RETURNS TRIGGER AS $$
DECLARE current_time timestamp := now(); suffix text := date_part('month', now())||'_'||date_part('day', now()) ;
BEGIN RAISE NOTICE '%', suffix; execute 'insert into t1_'||suffix||' values( NEW.* )'; RETURN NULL;
END;
$$
LANGUAGE plpgsql;
I searched the archives here and after reading your previous mail in
this thread, I started to look at plperl, with which I have no
experience at all.
As $_TD{new}{column} gives the value of field column, I thought to
extract all columns from keys($_TD{new}), but it doesn't seem to see
$_TD{new} as a hash:
Type of arg 1 to keys must be hash (not hash element)
And that's where I'm at now.
