Too few parameters error

Question

hi,
i keep getting the following error:
SQLException in PAUserBean - getWorkNumber java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.here is code:
public String getWorkNumber(String Id) {
     String workNumber = "";
     try {
          Connection conn = DriverManager.getConnection("jdbc:odbc:PA");
          Statement s = conn.createStatement();
          String sql = "SELECT WORKER.WORK_PHONE_NBR FROM WORKER WHERE WORKER.USER_ID=" + Id + ";";
          ResultSet rs = s.executeQuery(sql);
          if(rs.next()) {
               workNumber = formatPhoneNumber(rs.getString("WORK_PHONE_NBR"));     
     }catch(SQLException e) {
          System.out.println("SQLException in PAUserBean - getWorkNumber " + e.toString());
     return workNumber;
}here is the database map:
WORKER TABLE:
USER_ID - Number (primary key)
WORK_PHONE_NMR - Text
I'm using an MS Access database, when i run the following query in MS Access it returns the number:
SELECT work_phone_nbr
FROM Worker
where id=102;
odd thing is the jsp page does display the number, meaning the query is ok, but i see tomcat's log with that error, any ideas what it means? what parameter am i missing?
Thank you.

Answer 1

Enclose the parameter with single quotes. Also, you don't need the semi-colon.
String sql = "SELECT WORKER.WORK_PHONE_NBR FROM WORKER WHERE WORKER.USER_ID='" + Id + "'";
