tcustomerdao.java

这是我在东方标准学习的时候做的一个项目

package dao.product;

import java.sql.SQLException;
import java.util.List;

import bean.TCustomer;

public interface TCustomerDAO {

	public boolean add(TCustomer custom);

	public boolean update(TCustomer custom);

	public boolean delete(int customer_id);

	public TCustomer findById(int customer_id);

	public TCustomer findByIdInfo(String id_type, String id_number)
			throws SQLException;

	public List findAll();

}
