Using ROWTYPE to create undoable record

Question

Does anyone have any insight on how I would perform the following in forms:
Define a %ROWTYPE record
On Each Navigation to a new Record
Store all the record's values in %ROWTYPE variable
An UNDO button on the form would then revert all the values in the current record to the values stored in the %ROWTYPE variable.
I am new to this, I can't even seem to figure out how to define the %ROWTYPE variable, much less populate and revert the form's contents.
Thanks for your help.

Answer 1

1. Put a trigger on the table that populates the pk with the sequence
2. Change your procedure "PROMOTE" into a function that returns the new id
3. In your function code, use the "returning ... into" clause of an insert statement to get the new id:
create or replace function promote(
  p_early_proj_id in number)
return number
is
  l_new_id number;
begin
  insert into late_project (a,b,c) values (...) returning id into l_new_id;
  return l_new_id;
end promote;4. Call your function from a PL/SQL process like this:
:P8_NEW_LATE_PROJ_ID := PROMOTE(p_early_proj_id) ;This technique will also allow you to call this function from technologies other than APEX, instead of burning part of the logic into the APEX code itself.
