Remarks
You can construct an OracleLob that is NULL using this format:
OracleLob myLob = OracleLOB.Null;
This technique is used primarily to test whether a LOB returned from the server is NULL, as this example illustrates:
If(myLob == OracleLob.Null)
A NULL LOB behaves similarly to a zero byte LOB in that Read succeeds and always returns zero bytes.
