Represents a null OracleBFile object that is not bound to a physical file.
[Visual Basic] Public Shared ReadOnly Null As OracleBFile [C#] public static readonly OracleBFile Null; [C++] public: static OracleBFile* Null; [JScript] 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.
