2.数据操作

//查询

int number = 1001;
Employee emp = EmployeeManager.GetEmployee(number);
if (emp != null)
{
Response.Write(emp.FirstName + ' ' + emp.LastName);
}

//增加
Employee emp = new Employee();
emp.FirstName = "kenny";
emp.LastName = "jiang";
emp.EmployeeNumber = 2005;
emp.Title = "SSE";
Mapper.Instance().Insert("insertEmployee", emp);

//删除

ISqlMapper sqlMapper = Mapper.Instance();
Employee emp2 = Mapper.Instance().QueryForObject<Employee>("GetEmployee", 2);
sqlMapper.Delete("deleteEmployee", 2);

//修改
ISqlMapper sqlMapper = Mapper.Instance();
Employee emp = Mapper.Instance().QueryForObject<Employee>("GetEmployee", 1);
emp.FirstName = "kenny2";
emp.LastName = "jiang2";
emp.EmployeeNumber = 20052;
emp.Title = "SSE2";
sqlMapper.Update("updateEmployee", emp);

//查询全部

ISqlMapper sqlMapper = Mapper.Instance();
IList<Employee> empList = Mapper.Instance().QueryForList<Employee>("GetAllEmployee",null);
foreach (Employee emp in empList)
{
Response.Write(emp.Title + "<br/>");
}

//按照条件查询
Employee empCondition = new Employee();

ISqlMapper sqlMapper = Mapper.Instance();
IList<Employee> empList = Mapper.Instance().QueryForList<Employee>("GetAllEmployeeByCondition", empCondition);

//多表查询
