Question

//MyTest.java
import java.sql.*;
public class MyTest
     public static void main( String[] args )
          try
               Class.forName("org.gjt.mm.mysql.Driver");
          //     .newInstance();
               try
                    Connection con = DriverManager.getConnection( "jdbc:mysql://localhost:3306/test" );
                    try
                         Statement statement = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
                         ResultSet rs = statement.executeQuery("SELECT * FROM mytest");
                         ResultSetMetaData rsmd = rs.getMetaData();
                         String     columnname = rsmd.getColumnName(1);
                         int     columncount = rsmd.getColumnCount();
                         System.out.println(columnname + "     " + columncount);
                         System.out.println(rsmd.getColumnType(1));
                         System.out.println("\n");
                         while ( rs.next() )
                              System.out.println(rs.getString(1));
                         rs.close();
                         statement.close();
                    catch ( SQLException e )
                         System.out.println( "JDBC error: " + e );
                    finally
                         con.close();
               catch( SQLException e )
                    System.out.println( "could not get JDBC connection: " + e );
          catch( Exception e )
               System.out.println( "could not load JDBC driver: " + e );
on mysql, i created the table named mytest
mysql>create table mytest (name varchar(20));
mysql>insert into mytest values("hbsc");
then on the cmd windows
c:>java MyTest;
but i can not the the expected data.
while ( rs.next() )
                              System.out.println(rs.getString(1));
this statement print nothing, if debug infomation inserted into the while loop,
we can get the debug info,not the data. it seems nothing is fetched from the table. and when i change getString(1) to getString("name");
C:\>java MyTest

I've tried your program with a couple of small changes as shown below:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();  // use sun's driver instead
try {
   Connection con = DriverManager.getConnection( "jdbc:odbc:mysqldemo" );   // no need for host stuffand it works fine!
;o)
V.V.
PS: this is what I have on the system with Windows XP-Pro:
Product : MySQL, Version : 4.0.12-max-nt
Driver : JDBC-ODBC Bridge (myodbc3.dll), Version : 2.0001 (03.51.06)
