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. 2009/4/21 Vivien Malerba <vmale...@gmail.com> > > > 2009/4/19 Daniel Espinosa <eso...@gmail.com> > >> 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, > > Vivien > -- Trabajar, la mejor arma para tu superación "de grano en grano, se hace la arena" (R) (en trámite, pero para los cuates: LIBRE)
