Java.sql.SQLException: Expected to find "an identifier" instead found "?

Question

I am having trouble getting my prepared statements to work.
I have a DAO and a test class to call it.
SQLException caught!

Press any key to continue . . .
import java.sql.*;
public class contactDAO {
    private static String SELECTQUERY = "select * from contact";
    private String SELECTNAME = "SELECT * FROM CONTACT WHERE NAME = ?";
    private String INSERTNAME = "INSERT INTO CONTACT (?, ?, ?, ?, ?,?)";
    private static String DBCONNECTION = "jdbc:pointbase:server://localhost:9092/contacts";
    private static String USERNAME = "CONTACT";
    private static String PASSWORD = "CONTACT";
    public contactDAO () {
           try {
                  Class.forName ( "com.pointbase.jdbc.jdbcUniversalDriver" );
               } catch (Exception e) {
                  System.out.println("ERROR: failed to load pointbase JDBC driver.");
                  e.printStackTrace();
                  return;
    public static void main(String[] args)    {
        try {
            Class.forName ( "com.pointbase.jdbc.jdbcUniversalDriver" );
        } catch (Exception e) {
            System.out.println("ERROR: failed to load pointbase JDBC driver.");

            return;
        try {
            Connection c = DriverManager.getConnection(DBCONNECTION,USERNAME,PASSWORD);
            Statement  query = c.createStatement();
            ResultSet result = query.executeQuery(SELECTQUERY);
            System.out.println("------- Content of the Contact Table: ------------\n");
            while(result.next()) {
                System.out.println("\t" + result.getString("NAME") +
                                   "\t" + result.getString("STREET") +
                                   "\t" + result.getString("CITY"));
        catch(SQLException e) {
            System.err.println("SQLException caught!");
            e.printStackTrace();
    public ResultSet getContact (String name) {
          ResultSet rs = null;
       try {
        Connection c = DriverManager.getConnection(DBCONNECTION,USERNAME,PASSWORD);
        PreparedStatement ps = c.prepareStatement(SELECTNAME);
        ps.setString(1,name);
        rs = ps.executeQuery();
        } catch(SQLException e) {
            System.err.println("SQLException caught!");
            e.printStackTrace();
         return rs;
   public int setContact (String name, String street, String city, String state, int zipcode, String phone) {
        int rowcount = 0;
               try {
                Connection c = DriverManager.getConnection(DBCONNECTION,USERNAME,PASSWORD);
                PreparedStatement ps = c.prepareStatement(INSERTNAME);
                ps.setString(1,name); //,2,street,3,city,4,state,6,phone);
                ps.setInt(5,zipcode);
                rowcount = ps.executeUpdate();
                } catch(SQLException e) {
                    System.err.println("SQLException caught!");
                    e.printStackTrace();
        return rowcount;
}and now the test script...
import java.sql.*;
public class daoTest {
   public static void main(String[] args)    {
      int rowcount = 0;
      ResultSet rs = null;
      try {
            contactDAO cd = new contactDAO();
            cd.setContact("RALPH","123 My Street","Reston","Virginia",20194,"[phone]");
            cd.getContact("RALPH");
        /*    while(rs.next()) {
                   System.out.println("\t" + rs.getString("NAME") +
                                      "\t" + rs.getString("STREET") +
                                      "\t" + rs.getString("CITY"));
          } catch (Exception e) {
              System.out.println("ERROR: failed to load pointbase JDBC driver.");
              e.printStackTrace();
              return;
}

Answer 1

Some of the things that I note that are wrong with the above code.
- It isn't a DAO because it is encapsulating the data as well has the functionality.
- It is trying to return a result set outside of the scope of the statement.
- Resources are not being closed.
- Bind variables are not being set.
