Date Selection Problem

In the database, the 'trans_date' field(datatype is Date/Time) contains the following dates for the 'account_no' 3....

11/15/03
11/15/03
11/15/03
11/16/03
11/17/03
11/18/03

if I enter 11/15/03 as start date, and 11/20/03 as end date.... the program doesn't go to the next page but redirects to Transaction.jsp with an error showing "End Date is incorrect".... I'm sorry for posting the code once again..... JNic thanx for ur suggestions but what should I do if I can't get it then

if I enter a wrong account no, then "Start Date is incorrect" error is displayed although account_no error must b shown

jimmackCommented:
The error is being returned because no records are being found that match your query (ps1).

Are you sure the format of your end date is correct?

Since you pass all the parameters through to Transaction.jsp anyway, you should display the dates in addition to the error message.
JNicCommented:
Look at your first preparedStatement:

PreparedStatement ps = con.prepareStatement("select * from transaction1 where account_no = " + request.getParameter("acc_no") + " and trans_date >= " + sdate + "");

You test it like this (I cut out all in the middle):

ResultSet rs = ps.executeQuery();
  if(rs.next())
  {
    ..... // all your code
 }  
else{
    response.sendRedirect("Transaction.jsp?sdate=bad&month=" + request.getParameter("month") + "&day=" + request.getParameter("day") + "&year=" + request.getParameter("year") + "&month1=" + request.getParameter("month1") + "&day1=" + request.getParameter("day1") + "&year1=" + request.getParameter("year1") + "&acc_no=" + request.getParameter("acc_no") + "");
  }

This redirect will happen if you get no results comparing with the entered date OR if you enter a wrong account number. Therefore you get an invalid date error when you enter a bad account_no.

What you could do is to test for a wrong account no before all the other tests:

Make a very first statement:
"select * from transaction1 where acc_no="+request.getParameter("acc_no")
And then do a test, - if this returns no results, you should make the program return a bad_acc error.

Now note down the main problem plz

The 'trans_date' field in the Access database is fixed to Date/Time. I take 11/11/2003(mm/dd/yy) as input and this date exists in the database. But still the program jumps to the 'else' condition, i.e.

<%
   String sdate = request.getParameter("month") + "/" + request.getParameter("day") + "/" + request.getParameter("year");

PreparedStatement ps = con.prepareStatement("select * from transaction where account_no = " + request.getParameter("acc_no") + " and trans_date = " + sdate + "");

ResultSet rs = ps.executeQuery();
if(rs.next()){
   out.println("Hello");
}else{
   out.println("Bye");
}

//   The program jumps to else condition even if the input provided is correct or not.
%>

What's the solution for this problem?
JNicCommented:
The format of an SQL-date is normally: yyyy-mm-dd.

Are you sure this is not the case in your db? If I am right, you should change:

 String sdate = request.getParameter("month") + "/" + request.getParameter("day") + "/" + request.getParameter("year");

To

String sdate = request.getParameter("year")+"-"+request.getParameter("month")+"-"+request.getParameter("day");

Otherwise, I will suggest you try to do a sample print of the String. Then we can see if it look strange. So:

   String sdate = request.getParameter("month") + "/" + request.getParameter("day") + "/" + request.getParameter("year");

System.out.println(sdate); // Print the string

PreparedStatement ps = con.prepareStatement("select * from transaction where account_no = " + request.getParameter("acc_no") + " and trans_date = " + sdate + "");

ResultSet rs = ps.executeQuery();
if(rs.next()){
   out.println("Hello");
}else{
   out.println("Bye");
}
