669. What are OPEN_FORM,CALL_FORM,NEW_FORM? diff?
CALL_FORM : It calls the other form. but parent remains active, when called form completes the operation , it releases lock and control goes back to the calling form.
When you call a form, Oracle Forms issues a savepoint for the called form. If the CLEAR_FORM function
causes a rollback when the called form is current, Oracle Forms rolls back uncommitted changes to this
savepoint.
OPEN_FORM : When you call a form, Oracle Forms issues a savepoint for the called form. If the
CLEAR_FORM function causes a rollback when the called form is current, Oracle Forms rolls back
uncommitted changes to this savepoint.
NEW_FORM : Exits the current form and enters the indicated form. The calling form is terminated as
the parent form. If the calling form had been called by a higher form, Oracle Forms keeps the higher call
active and treats it as a call to the new form. Oracle Forms releases memory (such as database cursors)
that the terminated form was using.
Oracle Forms runs the new form with the same Runform options as the parent form. If the parent form was
a called form, Oracle Forms runs the new form with the same options as the parent form.
