OracleLoader not working with IDataReader

[utoracle]

I am evaluating the latest version of dotConnect for Oracle and I am running into an error while using OracleLoader.
When OracleLoader's LoadTable(IDataReader) gets executed, it throws an error "ORA-00957: duplicate column name".
The stack trace is:

Code: Select all

   at Devart.Data.Oracle.OracleCommand.a(Int32 A_0, Boolean A_1, Int64[]& A_2)
   at Devart.Data.Oracle.OracleCommand.ExecuteArray(Int32 iters)
   at Devart.Data.Oracle.cg.n()
   at Devart.Data.Oracle.OracleLoader.NextRow()
   at Devart.Common.DbLoader.LoadTableInternal(IDataReader reader)
   at Devart.Common.DbLoader.a(IDataReader A_0)

The source and destination tables are a replica of each other.
My code is:

Code: Select all

using (var loader = new OracleLoader("ABC.XYZ", conn, OracleLoaderOptions.NoLogging))
{
          loader.CreateColumns();
          string selectStatemnt = @"SELECT * FROM ABC.XYZCopy";
          using (OracleCommand comm = new OracleCommand(selectStatemnt, conn))
                    {
                        using (var dataReader = comm.ExecuteReader())
                        {
                            loader.LoadTable(dataReader);
                        }
                    }
}
