Value Gnome::Gda::QueryFieldValue::get_default_value | ( | ) | const |
Get the default value stored by field.

. bool Gnome::Gda::QueryFieldValue::get_not_null | ( | ) | const |
Tells if field can receive a 0
value.
true
if field can't have a 0
value. Value Gnome::Gda::QueryFieldValue::get_value | ( | ) | const |
Get the value stored by field.
If there is no value, but a default value exists, then the default value is returned.n it's up to the caller to test if there is a default value for field. The default value can be of a different type than the one expected by field.
