Sql exception :too few paprameters to update

Question

I am getting an sql exception in this query below.
It says too few parameters :expected 1
String query = "UPDATE INR SET " + month+ " = " + mnt+ " where (IT = '" + initial + "') AND (new = '" + later+ "' ) AND (number = '" + num + "' ) AND (code = '" + Id + "')";
I am just passing 1 telling it to update month column with mnt .
Thanks,

Here is my code with JDBC connecting to an Access Table
String data ="jdbc:odbc:MonthUpdateTable";
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");     
     Connection conn = DriverManager.getConnection(data, "", "");
     Statement st = conn.createStatement();
     String query = "UPDATE INR SET " + month+ " = " + mnt+ " where (IT = '" + initial + "') AND (new1 = '" + later+ "' ) AND (number = '" + num + "' ) AND (code = '" + Id + "')";
     System.out.println(query);
     st.executeUpdate(query);
     st.close();
          conn.close();
catch(Exception e) {System.out.println("UpdateError: " + e.toString()
           + e.getMessage());}
Thanks,
