You mean you use ObjectPtr field in the CHILD BaseObject ?

Yes, until you assign some value it points to NULL.
I.e. Record DO NOT have parent.

You can even do searches

    WHERE ptr = 0

No. it is not automatic.

You need

    parent fill fields
    parent.AddRecord

    child fill fields and...
    child.ptr = parent.GetRecID()
    child.AddRecord.


In fact you can assign/change PARENT record at any time.
This can be 5 days later.

    ptr is just INTEGER field. It store some value
            -- RecID of some record of parent table
