Using a prepared statement with auto increment field

Question

I am trying to do insert to a table whose primary key is set to auto increment using a prepared statement.

The fields in the table are as follows;

id, username, password, email, firstname, last name

My code is such that

    String sql = "INSERT INTO Users values (?,?,?,?,?, ?)";
    RegistrationStatus status = null;
    Connection conn = null;
    PreparedStatement st = null;
    try {
        conn = source.getConnection();
        st = conn.prepareStatement(sql);
        st.setString(2, username);
        st.setString(3, password);
        st.setString(4, email);
        st.setString(5, firstname);
        st.setString(6, lastname);
        st.executeUpdate();

Where i have read that we should no include the first item as the database will take care of it. This approach for me appears to be failing.

Would it be possible to get some help on how to solve this?

Change your statement to not include the id (or the exact name) column:

String sql = "INSERT INTO Users (username, password, email, firstname, lastname)"
    + " values (?,?,?,?,?)";
//...
st.setString(1, username);
st.setString(2, password);
st.setString(3, email);
st.setString(4, firstname);
st.setString(5, lastname);
//...
