All Implemented Interfaces:

Serializable, Cloneable, CoreField

public class ObjectRelationalDatabaseField
extends DatabaseField

INTERNAL: A database field of object-relational type: either a java.sql.Array, java.sql.Struct, or java.sql.Ref. Oracle drivers require the user defined field type name for these fields, along with the generic sqlType: ARRAY, STRUCT, or REF. Toplink can only recognize primitive field types like Integer or String, but here custom java objects are being written to a single field. Thus instead of DatabaseField#type the driver needs a string representing the user defined type of the structure on the database, and the type of field: either ARRAY, STRUCT, or REF. Added for bug 2730536.

Since:

OracleAS TopLink 10g (9.0.4)
