Gets the 'allow null' flag of the given column. 
- Returns
- Whether the given column allows null values or not (trueorfalse).
 
 
Get the value associated to a named attribute. 
Attributes can have any name, but Libgda proposes some default names, see this section. 
- Parameters
- 
  
    | attribute | Attribute name as a string. |  
 
- Returns
- A read-only Value, or 0if not attribute named attribute has been set for column.

          | static GType Gnome::Gda::Column::get_type | ( |  | ) |  |  | static | 
 
Get the GType for this class, for use with the underlying GObject type system. 
 
 
  
  | 
        
          | GdaColumn* Gnome::Gda::Column::gobj | ( |  | ) |  |  | inline | 
 
Provides access to the underlying C GObject. 
 
 
  
  | 
        
          | const GdaColumn* Gnome::Gda::Column::gobj | ( |  | ) | const |  | inline |

          | GdaColumn* Gnome::Gda::Column::gobj_copy | ( |  | ) |  | 
      
 
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

Column's Id (warning: the column's ID is not guaranteed to be unique in a GdaDataModel). 
You rarely need to use properties because there are get_ and set_ methods for almost all of them. 
- Returns
- A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.
