一个简单的存储过程数据分页

1。数据库结构为：(在SQL当中建立一个数据库后，直接在SQL结构查询器当中执行以下SQL脚本)

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[Mobile]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[Mobile]
GO

CREATE TABLE [dbo].[Mobile] (
 [MobileID] [int] IDENTITY (1, 1) NOT NULL ,
 [MobileType] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL
) ON [PRIMARY]
GO

2。存储过程，（可以直接在数据库中新建存储过程，然后复制到数据库）

/*

*/
CREATE PROCEDURE Proc_Paging
(
@TBName NVARCHAR(255) ,
@SQL nVARCHAR(4000),    --不带排序语句的SQL语句
@Page int,              --页码
@RecsPerPage int,       --每页容纳的记录数
@ID VARCHAR(255),       --需要排序的不重复的ID号
@Sort VARCHAR(255) ,     --排序字段及规则
@PageCount INT OUTPUT          --总页数
)
AS
BEGIN
 DECLARE @sql1 nvarchar(4000)
 SET @sql1=N'SELECT @PageCount=COUNT(*)'
  +N' FROM '+@tbname  
 EXEC sp_executesql @sql1,N'@PageCount int OUTPUT',@PageCount OUTPUT
 SET @PageCount=(@PageCount+@RecsPerPage-1)/@RecsPerPage
END
BEGIN
DECLARE @Str nVARCHAR(4000)
SET @Str='SELECT   TOP '+CAST(@RecsPerPage AS VARCHAR(20))+' * FROM ('+@SQL+') T WHERE T.'+@ID+' NOT IN (SELECT   TOP '+CAST((@RecsPerPage*(@Page-1)) AS VARCHAR(20))+' '+@ID+' FROM ('+@SQL+') T9 ORDER BY '+@Sort+') ORDER BY '+@Sort
--PRINT @Str
--EXEC sp_ExecuteSql @Str
--EXEC @Str
DECLARE @Str1 NVARCHAR(400)
DECLARE @Str2 NVARCHAR(400)
SET @Str1 = CAST(@RecsPerPage AS VARCHAR(20))
SET @Str2 = CAST((@RecsPerPage*(@Page-1)) AS VARCHAR(20))
EXEC ( N'SELECT   TOP '+@Str1+ N' * FROM ('+@SQL+N') T WHERE T.'+@ID+N' NOT IN (SELECT   TOP '+@Str2+N' '+@ID+N' FROM ('+@SQL+N') T9 ORDER BY '+@Sort+N') ORDER BY '+@Sort )
END
GO
