Blob/Clob object is either closed or invalid
 If you retrieve a smart large object using the ResultSet.getBlob() or ResultSet.getClob() method
or create one using the IfxBlob() or IfxCblob() constructor,
a smart large object is opened. You can then read from or write to
the smart large object. After you execute the IfxBlob.close() method,
do not use the smart large object handle for further read/write operations,
or this exception is thrown.
