工作中一些常用到的代码记录下来，方便自己查找也方便其他需要人士参考。

废话不多说，这是一个向上向下排序的功能，首先使用存储过程 整好 如下：

sql:

alter procedure [dbo].[sp_bannerorder]

-- add the parameters for the stored procedure here

(

@tablename nvarchar(50), --表名

@colname nvarchar(50), --排序字段

@keyid nvarchar(50), --表主键字段

@keyidvalue int, --表主键字段值1

@order nvarchar(20), -- 列表默认的排序方式，asc或desc

@orderdirection nvarchar(20), --排序方向，up或down

@where nvarchar(2000) --查询条件

)

as
