Oops, sorry for misreading your question. (However the SQL I gave you above is also very handy, and worth saving.)
Okay, this is off the top of my head and untested, but might just work. Assuming that your data block name is MYBLOCK, and that the item that you want to check for dups on is named MYNUM, create an item-level WHEN-VALIDATE-ITEM trigger with the following code.
declare
l_newest_record number(10) := :system.cursor_record;
l_newest_mynum number(10) := :myblock.mynum;
l_dup_found boolean := false;
begin
-- In this loop, we skip backwards through all new records to look for dups.
while :system.cursor_record > 1 loop
previous_record;
if :system.record_status = 'NEW' then
if :myblock.mynum := l_newest_mynum then
l_dup_found := true;
exit; -- Dup found!
end if;
else
exit; -- We've gone backwards past the first new record.
end if;
end loop;
-- In this loop, we return to the current record.
while :system.cursor_record < l_newest_record loop
next_record;
end loop;
if l_dup_found then
raise duplicate_row_found; -- user-defined exception
end if;
end;
The above code only checks for dups in the new form records. It assumes that a unique constraint in the database will deal with records actually committed.
