ODB requires that Oracle persist statements include a RETURNING clause so that
a generated auto_id column value may be returned.
|
|
This is not necessary and is more complex than originally thought due to the
possibility of auto_id columns having a char* image type.

Oracle interprets empty VARCHAR2 and NVARCHAR2 strings as NULL. As an empty
string is always valid within the C++ context, VARCHAR2 and NVARCHAR2 columns
are always specified as nullable.

The null state of the image is established in-line when traits set_value
