OracleLob.Value Property

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

Gets the common language runtime stream value equivalent of the underlying value.

[Visual Basic]
Public ReadOnly Property Value As Object
[C#]
public object Value {get;}
[C++]
public: __property Object* get_Value();
[JScript]
public function get Value() : Object;

Property Value

For Blob, an array of type Byte[]. For Clob and NClob, a String. For null data, DBNull.

Exceptions

Exception Type Condition
ObjectDisposedException The object was closed or disposed.
OracleException An Oracle error has occurred.

Remarks

For Blob data types, Value returns the entire underlying data as a contiguous array of type Byte[]. For Clob and NClob data types, Value returns all the data as a String. For null data, Value returns DBNull. By comparing the returned values, you can distinguish among empty data, null data, and data.

Note   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 Value, you obtain all the data for the LOB column as one contiguous chunk, which can significantly increase application overhead.
