S2Dao

RELNOをNの方に書いて、RELKEYは同じだから書かずに（書いても書かなくてもエラーが変わらない(T.T)）DaoでARGのうしろに_0ってかいてる・・・
なのにエラー〜
ARG書かなきゃエラーにはならないんだけど、目的が達成出来ない(笑)

public class Car implements Serializable {
	public static final int carMaker_RELNO = 0;
	private int carID;
	private String carName;
	private int makerID;
	private CarMaker carmaker;

public class CarMaker implements Serializable {
	public static final String TABLE = "maker";
	
	private int makerID;
	private String maker;

public interface CarDao {
	public Class BEAN = Car.class;
	public String getCarByMaker_ARGS = "maker_0";
	public List getCarByMaker(String maker);
}

こんな感じのコード
CarがNでCarMakerが1
