This constructor creates an instance of the OracleRef class with a connection and a HEX string that represents an REF instance in the database.

Declaration

// C#
public OracleRef(OracleConnection con, string hexStr);

Parameters

• con

  An OracleConnection instance.

• hexStr

  A HEX string that represents an REF instance in the database.

Exceptions

ArgumentException - The HEX string does not represent a valid REF in the database.

ArgumentNullException - The connection or HEX string is null.

Remarks

When an OracleRef instance is created, it is referenced to a specific table in the database.

The connection must be opened explicitly by the application. OracleRef does not open the connection implicitly.
