Re: returning inserted id

Matt,

This is how you can do it:

create function person_ins(_name text)
returns integer
language plpgsql
as $$

declare
insert_id integer;
begin
insert into person (name) values(_name);
select into insert_id currval('person_id_seq');
return insert_id;
end;
$$;

Or perhaps even better: you return the whole inserted row (in 8.1 with INOUT
parameters):

create function person_ins(_name text)
returns person
language plpgsql
as $$

declare
inserted_row person;
begin
insert into person (name) values(_name);
select into inserted_row * from person where id=currval('person_id_seq');
return inserted_row;
end;
$$;

Hope there is no syntax error.

Best Regards,
Otto
