No. Large Objects are not stored directly inline, but as a pointer to
other storage. The getLong is retrieving the external storage which
Jdbc4Clob will then stream from the server on demand. You are probably
trying to call getClob on a text or varchar column and that's not going to
work. It might be nice to provide that interface, but there's no benefit
(other than compatibility) to the user. If you have text data stored
inline, then it's already been transferred over to the client side in the
ResultSet, so there's no point in using a streaming interface.
