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