I have a trigger that is not firing, I assume that my like statement is not correct but am not having any luck on the solution. The trigger looks like this...
create trigger trig1
after insert or update of val on table1
for each row
begin
update table2 set tn = tn
where tn like ':new.val';
end;

What is the purpose of this update? You are just setting the value of a column to itself. Also, the single quotes around :new.val are not needed (it is looking for the literal string ':new.val' - not the value of :new.val. If :new.val does not contain %, you should use = instead.
create or replace trigger trig1
after insert or update of val on table1
for each row
begin
update table2
set tn = 'updated' -- something other than tn I would think...
where tn = :new.val;
end;
