Q for TimYates/Ken/kludeep

I am following ChainReaction's q previously and i fee curious and try it out my own. Yet, i found the same error like he did... and it's not good for me to tap into his question.. hope 3 of us can help me as well...

ha..

I have create the same DB he have, Access, with Date(InsDateA) and datatye is date.
this is my code:


   PreparedStatement ps = conn.prepareStatement( "SELECT * FROM PURCHASE WHERE "+
    " (ExpDateA > ? AND ExpDateA < ?)" ) ;  
 
   ps.setDate( 1, new java.sql.Date( sdf.parse( startdate ).getTime() ) );
   ps.setDate( 2, new java.sql.Date( sdf.parse( enddate ).getTime() ) );

rs=ps.executeQuery();
int counter=0;
while (rs.next()){
    counter++;
    out.println("<BR>");
out.println(counter + ":"+ rs.getString("Customer") + vf.format(rs.getDate("ExpDateA")));
vf.format(rs.getDate("ExpDateB")) );
    out.println("<BR>");

this is the rawdata.
ExpDateA
11/27/2004
11/26/2005
11/20/2003
12/18/2003
11/24/2003

And this is my result page:

Start Date : 01/11/2003 End Date : 30/11/2003

ha.. the first data shouldnt come out.. but i couldn't notice what went wrong... i did try whay TimeYates explain to Chainreaction, but i think i have the same problem with him... :-)

if i change the query again...
Start Date : 01/11/2003 End Date : 15/11/2003

1:KIMURA20/11/2003

2:KAWASKI24/11/2003

3:NAKATA18/12/2003
