Re: [gnome-db] Libgda 4.1.0 released

[Daniel Espinosa <esodan gmail com>]

To get the data row from the DB at object constructor run a SELECT query returning a GdaDataSelect, but in order to manage modifications I'm using a GdaDataProxy using the returning GdaDataSelect, then to modify the data I call gda_data_model_* functions over the GdaDataProxy, and then commint changes when finish to modify each column's value (csh_object_update wraps gda_data_proxy_apply_all_changes)

I haven't deside if I will have a Global GdaDataProxy and the object must refers to one and only one object in it, in order to avoid run multiple SELECT queries each time a new object is created; for today implementation, when open a data from the data base it runs a SELECT query with a WHERE id = ID, returning a GdaDataSelect object with just one row, may be adding a *_new function with a GdaDataModel and row number could resove the problem and allows the developer to use a per object query or a global data model.

I'm creating a financial library to record operations for accounting using libgda, and I've created a CshObject to get a row from a table to get its columns values or modify them, may be this object could be part of GDA you can see the code for csh-object.c/h at:

http://libcash.svn.sourceforge.net/viewvc/libcash/trunk/libcash/

I don't understand how it works because sometimes the priv->model is a GdaDataProxy, and sometimes it's a GdaDataSelect.

Cheers,
