Whether the given column is an auto incremented one (true or false).

Glib::ustring Gnome::Gda::Column::get_dbms_type (  )  const

Returns:
The dbms_type of column.

Value Gnome::Gda::Column::get_default_value (  )  const

Returns:
column's default value, as a Value object.

Returns:
The type of column.

Glib::ustring Gnome::Gda::Column::get_name (  )  const

Returns:
The name of column.

gint Gnome::Gda::Column::get_position (  )  const

Returns:
