Reorder upd.,ins. records after pressing commit (forms 6i) is it possible=

Question

Hello, looking for simple way or is it possible to reorder saving of records in a block.
(FORMS 6i)
Something like this:
1)I have detail block DB table (after Database query the data is) :
abc_fk , abc_order, abc_text
001 01 some text1
001 02 some text2
001 03 some text3
001 04 some text4
2)Now the user, wants to add new text after 1st line. I reorder the abc_order fields to
001 01 some text1
*001 02 NEW RECORD <-- new user input.*
001 03 some text2
001 04 some text3
001 05 some text4
After pressing commit button i get constrain error (uniqe key: abc_fk , abc_order).
Commiting process is going from top down , is it possible from buttom-up?
Now what happans is: forms put UPDATE on new record: 001 03 some text2 /when in database allready exsists record with same (sq, and order) that's: 001 03 some text3, so i get constrain error. (both record have same values: 001,03)
If forms could save records starting with
update 001 05 some text4,
update 001 04 some text3,
update 001 03 some text2,
insert *001 02 NEW RECORD <-- new user input.*
the problem is solved. Is this possible, to change order of saving?
Thank you for any help. :)

Hey, your update kind'a work :)
If user inserts and updates (in between) more then one row.. the order changes...(not the way it shows on the screen)
picture this DB table:
001 01
<-------- insert here (new record 2)
001 02
001 03
001 04
<-------- insert here (new record 6)
001 05
001 06
AFTER COMMIT WE GET:
001 01
<-------- insert here (new record 2) ok 001 08
001 03
001 04
001 05
001 06
<-------- insert here (new record 6) not ok 001 07
001 08
So in pre-insert trigger how can i/we/you/program know that it should do :)
UPDATE TABLE_NAME
     SET abc_order = abc_order + 1
     WHERE abc_fk >= '002'
     AND abc_order >= '05' and not ... AND abc_order >= '06' (which is the current new value of newly 2nd inserted statment
I changed pre-insert to:
     UPDATE abc
     SET abc_sq =:abc.abc_sq + 1
     WHERE abc_id = :abc.abc_id
     AND abc_sq >= :abc.abc_sq;
So i am still asking if it's possible, to change order of FORMS commitng from top-down to buttom - up. :)
I still want to know if there si a chance to change forms order of saving to save records starting with:
update 001 05 some text4,
update 001 04 some text3,
update 001 03 some text2,
insert 001 02 NEW RECORD <-- new user input.
Abut datatype you are right. We all use pading, and it's old database/table..
