工作中一些常用到的代碼記錄下來，方便自己查找也方便其他需要人士參考。
廢話不多說，這是一個向上向下排序的功能，首先使用存儲過程 整好 如下：
sql:
-- =============================================
-- author:
-- create date:
-- description:
-- =============================================
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), --表主鍵字段
@keyidvalue int, --表主鍵字段值1
@order nvarchar(20), -- 列表默認的排序方式，asc或desc
@orderdirection nvarchar(20), --排序方向，up或down
@where nvarchar(2000) --查詢條件
)
as
begin
declare @ordertmp1 int; --臨時排序值id1
declare @ordertmp2 int; --臨時排序值id2
declare @tmpkeyidvaule nvarchar(50);
declare @sql nvarchar(2000);
declare @parmdefinition nvarchar(500);
declare @parmdefinition2 nvarchar(500);
if @order='asc'
begin
set @sql = n'select @ordertmp1out='+@colname+' from where as nvarchar(50));
set @parmdefinition = nvarchar(20) output';
execute sp_executesql @sql, @parmdefinition, @ordertmp1out=@ordertmp1 output;
if @orderdirection='up'
begin
set @sql = n'select top 1 @ordertmp2out='+@colname+',@tmpkeyidvauleout='+@keyid+' from where as nvarchar(50))+' and order by desc';
end
else
begin
set @sql = n'select top 1 @ordertmp2out='+@colname+',@tmpkeyidvauleout='+@keyid+' fromwhere as nvarchar(50))+' and order byasc';
end
set @parmdefinition = nvarchar(20) output, @tmpkeyidvauleout nvarchar(20) output';
execute sp_executesql @sql, @parmdefinition, @ordertmp2out=@ordertmp2 output, @tmpkeyidvauleout=@tmpkeyidvaule output;
end
else
begin
set @sql = n'select @ordertmp1out='+@colname+' from where as nvarchar(50));
set @parmdefinition =nvarchar(20) output';
execute sp_executesql @sql, @parmdefinition, @ordertmp1out=@ordertmp1 output;
if @orderdirection='up'
begin

end
else

end

end
set @sql = 'update set as nvarchar(50))+' where as nvarchar(50));
set @sql = @sql + ' update + ' set as nvarchar(50))+' where as nvarchar(50));
--select @ordertmp1,@ordertmp2,@tmpkeyidvaule,@sql
exec(@sql);
end
model：

};
return convert.toint32( sqlhelper.executenonquery(configuration.connectionstring, commandtype.storedprocedure, sp_bannerorder, paras));
bll代碼:
