Hello!
Please, help me!
Can I create working trigger on view?
The problem is: I need a plpgsql function that execute on insert (or update, or delete) into view and knows the *OLD*
and*NEW*. (Number of fields can be more than 16)
Something like this:
Create Sequence id; Create Table t1(id1 int4, last_name varchar(32), time_create_t1); Create Table t2(id2 int4,
first_namevarchar(32), time_create_t2); Create View name as Select * from t1 a, t2 b where a.id1=b.id2; Create Rule
rl_ins_nameason INSERT to name do instead nothing; -- without it trigger is not allowed Create Function fn_ins_name()
returnsopaque as ' Declare v_time_create timestamp; Begin v_tm_create:=current_timestamp; Insert into t1(id1,
last_name,time_create_t1) values(nextval(''id''), new.last_name, v_time_create); Insert into t2(id2,
first_name,time_create_t2) values(currval(''id''), new.first_name, v_time_create); return null; End; '
Language'plpgsql'; Create Trigger tr_ins_name before INSERT on now_cis_user for each row execute procedure fn_ins_name;
This example is very simple. The trigger is not fired.
Sorry for my English.
