sure here it is. Just compile and execute with
gcc gda-data-model-concat.c example.c `pkg-config --cflags --libs
libgda-4.0` `pkg-config --cflags --libs glib-2.0` -o example && ./example

As you see from the example, I first try to use the GdaDataModelIter,
unsuccesfully, secondly I just try to query the items directly from the
GdaDataModelConcat, successfully.

Honestly I didn't get why gda-data-model has a virtual method
gda_data_model_iter_at_row, which seems to be implemented in
GdaDataSelect but with too much logic.


thanks and regards,
Massimo
