Package oracle.sql

Class REF

java.lang.Object

oracle.sql.Datum

oracle.sql.DatumWithConnection

oracle.sql.REF

All Implemented Interfaces:

Serializable, Cloneable, Ref, oracle.jdbc.internal.ACProxyable, oracle.jdbc.internal.OracleConcreteProxy, oracle.jdbc.internal.OracleDatumWithConnection, oracle.jdbc.internal.OracleRef, OracleRef

public class REF
extends DatumWithConnection
implements oracle.jdbc.internal.OracleRef, Serializable, Cloneable, oracle.jdbc.internal.OracleConcreteProxy

Deprecated.

Use java.sql.Ref interface for declaration instead of using concrete class oracle.sql.REF.

The REF class is a representation of the Oracle REF datatype, and it implements the java.sql.Ref interface. Use Ref interface for declaration instead of using concrete class oracle.sql.REF. java.sql.Ref has methods declared for all opertions. For Oracle specific methods use the interface OracleRef.

Obtaining java.sql.Ref from ResultSet

java.sql.Ref ref = resultSet.getRef(...);

There is no way to create Ref on the client side.

• OracleRef
