OracleBFile.Null Field

Note: This namespace, class, or member is supported only in version 1.1 of the .NET Framework.

Represents a null OracleBFile object that is not bound to a physical file.

[Visual Basic]
Public Shared ReadOnly Null As OracleBFile
public static readonly OracleBFile Null;
public: static OracleBFile* Null;
public static var Null : OracleBFile;


Null can be useful when you want to perform a comparison operation on an OracleBFile to determine nullability.

Any attempt to perform a read operation on a Null object succeeds, but does not return any data. Any attempt to perform a write operation on a Null object generates an exception. Selecting a BFILE column that contains a null value returns Null.
