Re: [GENERAL] insert into view !!

Try this script:

create table emp (
empno int,
ename char(10),
jobchar(12),
hiredate date,
saldecimal(10,2),
commint,
deptno int,
nivel int,
mgrint
);

create view vista
as select empno, ename, job
from emp
where job='SALESMAN';

create function view_upd() returns opaque as '
begin
if tg_op = ''INSERT'' then
if new.job = ''SALESMAN'' then
INSERT INTO emp VALUES (new.empno,new.ename,new.job);
return new;
else
raise notice ''impossible to add records where JOB is
not "SALES
return null;
end if;
end if;
end;
' language 'plpgsql';

create trigger t_add before insert
on vista for each row execute procedure view_upd();
