The parameters in a ``++PreparedStatement++`` are numbered from 1, not 0, so using any "set" method of a ``++PreparedStatement++`` with a number less than 1 is a bug, as is using an index higher than the number of parameters. Similarly, ``++ResultSet++`` indices also start at 1, rather than 0


== Noncompliant Code Example

----
PreparedStatement ps = con.prepareStatement("SELECT fname, lname FROM employees where hireDate > ? and salary < ?");
ps.setDate(0, date);  // Noncompliant
ps.setDouble(3, salary);  // Noncompliant

ResultSet rs = ps.executeQuery();
while (rs.next()) {
  String fname = rs.getString(0);  // Noncompliant
  // ...
}
----


== Compliant Solution

----
PreparedStatement ps = con.prepareStatement("SELECT fname, lname FROM employees where hireDate > ? and salary < ?");
ps.setDate(1, date);
ps.setDouble(2, salary);

ResultSet rs = ps.executeQuery();
while (rs.next()) {
  String fname = rs.getString(1);
  // ...
}
----
