[dabo-users] how to make dabo understand whether to delete/update/insert

Consider a setup like this:

ParentTable: (parent_id, name, occu)

ChildTable: (child_id, parent_id, name, qual)

GrandChildTable: (gchild_id, child_id, name, age)

Table data is like this:

in ParentTable: (1, 'John', 'farmer')

in ChildTable: (1, 1, 'Bill', 'B.A.'), (2, 1, 'Black', 'M.A.')

in GrandChildTable: (1, 2, 'Noah', 23), (2, 2, 'George', 10)

My Problem---

In GrandChildTable,

user deletes 2nd row.

updates 1st row.

Beforehand, I, of course, do not know what the user will do with records

(update or delete).

I know how to call the methods like new(), save(), delete(), seek() &

setFieldVal() individually on table records.

Is there any way to make dabo call delete() on correct records and save()

on correct records (without any extra coding from my side)?

Maybe something like setDeleteFlag?

Otherwise I need to trace-out the records where data was there before

user-interaction, and the data is absent after user-interaction.

Then I can call delete().

Otherwise I call save()

(along-with requery(), seek(), setFieldVal())

Similarly, I have to trace-out newly added records.

This becomes very complex.

Definitely, dabo must be having a proper way to do this.

I request this list to help me out.

Thanks,

Vineet
