Gets the common language runtime stream value equivalent of the underlying value.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
For Blob data types, returns the entire underlying data as a contiguous array of type Byte. For Clob and NClob data types, returns all the data as a String data type. For null data, returns DBNull. By comparing the returned values, you can distinguish among empty data, null data, and data.
A benefit of using LOB data types is the capability to retrieve large amounts of data in chunks at the client. However, when you use , you obtain all the data for the LOB column as one contiguous chunk, which can significantly increase application overhead.
