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
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
// ...
}
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);
// ...
}
