Dynamically Display table data

Question

Hello all
Can anyone help me with the following. I am trying to display data as follows
          disc1   disc2    disc3    disc4
type1       23       24       25       11
type2       11        7         31       10etc where the disc is dynamic in that there could be more or less data in the database.
I have the following code so far (see below) but have been unable to combine them to produce the above, what I really need is someway to print out the the type once and the amount for each disc where the disc is variable. Any ideas anyone?
ResultSet disks;
disks = GetResultSet("SELECT Distinct Disks from Metrics where Branch='" + request.getParameter("Branch") + "' order by Disks");
out.println("<tr>");
while (disks.next()) {
     out.println("<td colspan=2>" + disks.getString("Disks") + "</td>");
out.println("</tr>");
rs = GetResultSet("SELECT Disks,Type,MB from Metrics where Branch='" + request.getParameter("Branch") + "' order by Disks");
String sDisks;
sDisks = rs.getString("Disks");
while (rs.next()) {
out.println("<td>" + rs.getString("Type") + "</td><td>" + rs.getInt("MB") + "</td>");

Answer 1

There are a couple of things that will affect the implementation of this.
Is there a value of "disc" for every type?
If so, you could do something like the following:
- order by type - every time you find a new type, start a new row.
rs = GetResultSet("SELECT Disks,Type,MB from Metrics where Branch='" + request.getParameter("Branch") + "' order by Type, Disks");
  String currentType = "";
  boolean first = true;
while (rs.next()){
  String type = rs.getString("Type");
  if (!currentType.equals(type)){
// start a new row
    if (first){
      first = false;
    else {
            out.println("</tr">);
     out.println("<tr>");
  out.println("<td>" + rs.getString("Type") + "</td><td>" + rs.getInt("MB") + "</td>");
out.println("</tr>");If there isn't a type of disc for each row, it will be a bit more complicated.
You might consider loading the data into an intermediate datastructure (2d array?)
This would make it much easier to display.
Good luck,
