SqlServer 2000、2005分页存储过程整理

投稿:junjie

这篇文章主要介绍了SqlServer 2000、2005分页存储过程整理,本文给出了4个实现版本,还给出二分分页过程,需要的朋友可以参考下

sql server 2005的分页存储过程分3个版本,一个是没有优化过的,一个是优化过的,最后一个支持join的,sql server 2000的分页存储过程,也可以运行在sql server 2005上,但是性能没有sql server 2005的版本好。

在最后 我还附带了一个二分法的分页存储过程,也很好用的说哈~~

1.SqlServer 2005:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE proc [dbo].[up_Page2005]
 @TableName varchar(50),    --表名
 @Fields varchar(5000) = '*',  --字段名(全部字段为*)
 @OrderField varchar(5000),    --排序字段(必须!支持多字段)
 @sqlWhere varchar(5000) = Null,--条件语句(不用加where)
 @pageSize int,          --每页多少条记录
 @pageIndex int = 1 ,      --指定当前为第几页
 @TotalPage int output      --返回总页数
as
begin

  Begin Tran --开始事务

  Declare @sql nvarchar(4000);
  Declare @totalRecord int;

  --计算总记录数

  if (@SqlWhere='' or @sqlWhere=NULL)
    set @sql = 'select @totalRecord = count(*) from ' + @TableName
  else
    set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' with(nolock) where ' + @sqlWhere

  EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--计算总记录数

  --计算总页数
  select @TotalPage=CEILING((@totalRecord+0.0)/@PageSize)

  if (@SqlWhere='' or @sqlWhere=NULL)
    set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField + ') as rowId,' + @Fields + ' from ' + @TableName
  else
    set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField + ') as rowId,' + @Fields + ' from ' + @TableName + ' with(nolock) where ' + @SqlWhere

  --处理页数超出范围情况
  if @PageIndex<=0
    Set @pageIndex = 1

  if @pageIndex>@TotalPage
    Set @pageIndex = @TotalPage

   --处理开始点和结束点
  Declare @StartRecord int
  Declare @EndRecord int

  set @StartRecord = (@pageIndex-1)*@PageSize + 1
  set @EndRecord = @StartRecord + @pageSize - 1

  --继续合成sql语句
  set @Sql = @Sql + ') as t where rowId between ' + Convert(varchar(50),@StartRecord) + ' and ' + Convert(varchar(50),@EndRecord)
   print @sql
  Exec(@Sql)
  ---------------------------------------------------
  If @@Error <> 0
   Begin
    RollBack Tran
    Return -1
   End
   Else
   Begin
    Commit Tran
    Return @totalRecord ---返回记录总数
   End
end
