希望提供一个新的方法,或者传入一个可选项参数
使得数据查询的时候 查出来的字符串类型 映射到对应字段希望能进行 RTRIM()处理,
原因:
1.绝大多数字符串字段都要进行RTRIM()方法处理 ,
2.加上RTRIM 可读性变差,尤其是嵌套处理的情况
如下代码:
a.EventMemo,
RTRIM(a.UserID) As UserID,
RTRIM(ISNULL(c.Name, a.UserID)) AS [InUser],
RTRIM(ISNULL(po.sw_shipvia,0)) AS ShipViaCode,
RTRIM(ISNULL(po.TransportationTypeCode,0)) AS TransportationTypeCode,
目前采取两种方式解决为空数据 Reader问题,使用有点复杂,
方法一>代码里面可以用 IsDBNull(int ordinal)方法先进行判断
if (!reader.IsDBNull(reader.GetOrdinal("MiddleName"))) Console.Write(" {0}", reader.GetString(reader.GetOrdinal("MiddleName")));
方法二>数据库sql查询 进行 isnull判断处理
希望能进行封装
