Re: error when using move, any suggestions?

Dave,

Many thanks for your time. Unfortunalty, I'm still getting the same
error, even with the code you send, modified to use my database.

import blastDb.*;
import java.sql.*;
import java.io.*;
import java.util.*;
import java.lang.*;

public class TestFetchSize{
    public static void main(String[] args){
        Connection connection = null;
        ResultSet rs;
        try{
            connection = new BlastDB().connection;
            connection.setAutoCommit(false);
            Statement stmt = connection.createStatement();
            int counte = 0;
            int result = stmt.executeUpdate("declare test cursor for
select id from region " +
                    "where protein_database = 1");
            System.out.println("Cursor created, result is: " + result);
            result = stmt.executeUpdate("move forward 99 in test");
            System.out.println("Moved 99, result is: " + result);
            while(true){
                rs = stmt.executeQuery("fetch forward 2 in test");
                if (rs.next()){
                    ++counte;
                    while (rs.next()){
                        ++counte;
                        System.out.println("Id --> " +
rs.getObject(1).toString());
                    }
                }
                else
                    break;
            }
            System.out.println(counte);
            rs.close();
            connection.commit();
            connection.close();
        }
        catch (Exception e) {
            e.printStackTrace();
            System.out.println(e.getMessage());
        }
        finally{
            try{
                if(null != connection)
                    connection.close();
            }
            catch(Exception e) {}
        }
    }
}

With the move statement commented out it works fine.
The database is running on an IBM server with 4 Intel(R) Xeon(TM) CPU
1.40GHz.
The programe is running on a 1.2Ghz Athon machine with debin linux and
1Gig Ram.
I don't know if this helps at all.
Is there anyother info which may help you??
Once again many thanks for your help.
Noel
