Triggers

Hi,

Just doing some testing at the moment and trying to make a trigger that
consists of a insert statement which as a result of an sql querty!

Is this possible? if so could someone give me some pointers as i am
having no luck trying to get this to work, have even tried this but
still doesnt work.

begin
begin
INSERT INTO wip.resourceplan
(
"name",
"notes",
"hrs",
"glcode1",
"glcode2",
"chargeratename",
"chargeratevalue",
"servicefeename",
"servicefeevalue")

('1','2','3','4','5','6','7','8','9')
return null;
end;
