Hi,
I doing a log to my DB. For this, I writing a trigger that inserts in a
log table the user, date, table changed and values changed.
I was trying to do a generic procedure and use it on all tables, like
this:
create function sp_log() returns opaque as '
declare
v_type text;
v_taable text;
v_oid text;
v_old text;
v_new text;
begin
v_type := tg_op;
v_table := tg_relname;
v_oid := tg_relid;
-- v_old := old::text;
-- v_new := new::text;
insert into log (tablechanged, action, old_values, new_values, user)
values (v_tabela, v_tipo, v_old, v_new, current_user);
return new;
end;' language 'plpgsql';
How I do to get the old and new values in a generic way (without use
coluns names or any else that bind a specific table)?
Thanks for all help,
Edipo Elder
