[gnome-db] how to get gda_data_model_query_set_modification_query work?

[paragasu <paragasu gmail com>]

i am a bit confuse about gda_data_model_query_set_modification_query() function.
let say, i am not using any of GnomeDbRawGrid/GnomeDbGrid/ or
GnomeDbRawForm/GnomeDbRawForm, i can't use this function isn't?

Can anyone give a simple code example using this function without using any of
GnomeDb* ? i am interested to know, how i can update, delete, insert
using this..

thank you
