[gnome-db] SQL column default values

[Paisa Seeluangsawat <paisa unt edu>]

Hi,

I'm poking around a bit with libgda/libgnomedb, trying to
extend GnomeDbForm to let user create custom data-bound form
like in MS Access.

I would like to use the default value for each SQL column
when users create a new record, but I couldn't find an 
entry for it in GdaFieldAttributes.  Any clue?
