SQL QUERY IN JSP PAGE

Question

Dear Friends,
There is a table named as EXPENSES having fields as sl_no, name.
I want to find the MAXIMUM value of the sl_no.
For that i am using the query as " SELECT MAX(sl_no) FROM EXPENSES "
In JSP file my code is ......................
ResultSet rs= stmt.executeQuery(" SELECT MAX(sl_no) FROM EXPENSES ");
if(rs.next()) {
out.println(rs.getInt("sl_no"));
this out.println line throws a exception as "column not found"
My aim is just to find the maximu value of a field from a table by using the jsp as a front end.
So please reply me how can I slove that problem.

Answer 1

It should work: ID must be a table field.
StringBuffer buf = new StringBuffer(1024);
Statement stmt = connection.createStatement();
String ID = "2";
String val = null;
if (app != null) {
   buf.append("SELECT emp_name from table where ID  = " + "'" +ID + "'");
rs = stmt.executeQuery(buf.toString());
while (rs != null && rs.next()) {
   val = rs.getString(1);
