SQLX + ODP

Question

When my query accesses a permanent clob the extraction below works fine...
When it uses SQLX (temporary CLOB), it does not work anymore...
Error message is :
Oracle Data Provider for .NET throws Data provider internal error(-3001)
Oracle.DataAccess.dll : 9.2.0.4000
Query works fine under SQLPLUS.
This is a first try, so I must be doing something wrong...
Don't know what though !!!
Any better way to do this ???
using System;
using System.Data;
using Oracle.DataAccess.Client;
using Oracle.DataAccess.Types;
class Example
     OracleConnection con;
     void Connect()
          con = new OracleConnection();
          con.ConnectionString = "User Id=alain;Password=secret;Data Source=webdoc";
          con.Open();
          Console.WriteLine("Connected to Oracle");
     void Close()
          con.Close();
          con.Dispose();
     void GetData()
          string cmdQuery = "select XMLelement (\"processGroup\", pg_name ).getclobval() from PMP_process_groups";
          OracleCommand cmd = new OracleCommand(cmdQuery);
          cmd.Connection = con;
          cmd.CommandType = CommandType.Text;
          //cmd.XmlCommandType = OracleXmlCommandType.none;
          OracleDataReader reader = cmd.ExecuteReader();
          OracleClob clob;
          while (reader.Read())
               clob = reader.GetOracleClob(0);
               Console.WriteLine("pg " + clob.Value);
          reader.Dispose();
          cmd.Dispose();
     static void Main()
          Example example = new Example();
          try
               example.Connect();
               example.GetData();
               example.Close();
          catch ( OracleException e )
          Console.WriteLine("{0} throws {1}",e.Source, e.Message);
}

This is a known issue with the provider and the fix would be available in the next patchset release.
