GdaDataModel model = gda_connection_statement_execute_select(...) /* User level actions which reads/writes model data, as it is used as underlying data storage */ 2. gda_data_model_set_value_at (model, n, y, NULL); 3. update or delete or nothing gda_data_select_set_modification_statement would do the trick, but in such scenario I need to set values which are held by model before I actually may create particular GdaStatement. In other words. GdaDataModel is used as persistent (in memory) data storage, so I avoid duplicating its values when user needs read/write. Copying DataModel is not an option cause it's real performance bottleneck.
