Does Oracle LOBs support streams ?

Question

Hi
I am using Hibernate 3.2, Oracle 10g XE and
latest version (10.2.0.2) of thin jdbc driver (ojdbc14.jar). I would like to read from a CLOB using a stream, but it seems impossible. I can read from a CLOB using a Reader, it reads all 18kb of data I have stored there. But all streams return -1, if I try to read them and available() returns 0.
Report report = (Report) session.load(Report.class,reportName);
Clob reportXml = report.getReport();
Blob reportCompiled = report.getJasper();
SerializableClob sclob=(SerializableClob) reportXml;
CLOB oclob = (CLOB) sclob.getWrappedClob();
try
  log.warn(sclob.getAsciiStream().available());   // 0
  log.warn(oclob.getAsciiStream().available());   // 0
  log.warn(oclob.getAsciiStream(0).available());   // 0
  log.warn(oclob.asciiStreamValue().available());   // 0
  log.warn(oclob.binaryStreamValue().available());   // 0
  log.warn(oclob.getStream().available());          // 86
} catch(Exception ex) {}

Answer 1

you are trying to do packaged function overloading. it is
allowed in ORACLE.i think, error you are getting is some thing
else. create your functions outside package separately with
different names and test it. I think something wrong in
functions logic.
