谁能告诉我为什么我收到一个SQL * PLUS无效标识符错误？

      //get parameters from the request
   String homeID=request.getParameter(\"home_ID\");
   String modelID=request.getParameter(\"model_ID\");
   String lotSize=request.getParameter(\"lot_Size\");
   String location=request.getParameter(\"location\");
   String purchasePrice=request.getParameter(\"purchase_Price\");
   String streetName=request.getParameter(\"street_Name\");
   String city=request.getParameter(\"city\");
   String state=request.getParameter(\"state\");
   String zipCode=request.getParameter(\"zip_Code\"); 


  preparedStatement = conn.prepareStatement(\"INSERT INTO customer (home_ID, model_ID, lot_Size, location, purchase_Price    , street_Name, city, state, zip_Code)\"
                + \" VALUES (?,?,?,?,?,?,?,?,?)\");

   preparedStatement.setInt(1,Integer.valueOf(homeID));
   preparedStatement.setInt(2,Integer.valueOf(modelID));
   preparedStatement.setString(3,lotSize);
   preparedStatement.setString(4,location);
   preparedStatement.setInt(5,Integer.valueOf(purchasePrice));
   preparedStatement.setString(6,streetName);
   preparedStatement.setString(7,city);
   preparedStatement.setString(8,state);
   preparedStatement.setString(9,zipCode);
   preparedStatement.executeUpdate();

   CREATE TABLE home
