OracleBFile.Null Field

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

Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

'Declaration
Public Shared ReadOnly Null As OracleBFile
'Usage
Dim value As OracleBFile 

value = OracleBFile.Null

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.
