[gnome-db] How to use GdaDataModelQuery

["Daniel Espinosa" <esodan gmail com>]

I want to add a new row using a GdaDataModelQuery, but it sends
"invalid parameter '+0'" error, but whay if the GDA object sets all
parameters before ejecute the query

model = gda_data_model_query_new (query);
			
gda_data_model_query_compute_modification_queries
(GDA_DATA_MODEL_QUERY
(model),NULL,GDA_DATA_MODEL_QUERY_OPTION_USE_ALL_FIELDS_IF_NO_PK,NULL);


row = gda_data_model_append_row (model, &error);
				
if (row < 0)
   g_printf ("ERROR APPENDING: %s\n", error->message);

Even if I use a GdaDataProxy, append the row and then apply all
changes, the program sends the same message.
