使用 Petapoco 的 Column 和 ResultColumn 之间的区别？

Question

我 Class 喜欢

 public class Myclass
    {
        [Column]
        public string no{ get; set; }
        [Column]
        public string Name{ get; set; }
        [Column]
        public string Address{ get; set; }
        [Column]
        public DateTime DOB{ get; set; }
    }

我的select查询是

List<Myclass> list=DAL.db.Fetch("select b.ref_no no,a.name,a.Address,a.DOB from tbla a join tblb b on b.id=a.ref_id");

有时我会得到错误的结果，我得到了相同的结果record.I猜想我的class装饰变成了这样，

 public class Myclass
    {
        [ResultColumn]
        public string no{ get; set; }
        [ResultColumn]
        public string Name{ get; set; }
        [ResultColumn]
        public string Address{ get; set; }
        [ResultColumn]
        public DateTime DOB{ get; set; }
    }

Is an attribute which can decorate a Poco property to mark the property as a column. It may also optionally supply the DB column name.

结果列

Is an attribute which can decorate a Poco property as a result only column. A result only column is a column that is only populated in queries and is not used for updates or inserts operations.
