SqlServer 2000、2005分頁存儲過程整理

SqlServer 2000、2005分頁存儲過程整理

 sql server 2005的分頁存儲過程分3個版本，一個是沒有優化過的，一個是優化過的，最後一個支持join的，sql server 2000的分頁存儲過程，也可以運行在sql server 2005上，但是性能沒有sql server 2005的版本好。

在最後 我還附帶了一個二分法的分頁存儲過程，也很好用的說哈~~

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(全部字段為*)
 @OrderField varchar(5000),    --排序字段(必須!支持多字段)
 @sqlWhere varchar(5000) = Null,--條件語句(不用加where)
 @pageSize int,          --每頁多少條記錄
 @pageIndex int = 1 ,      --指定當前為第幾頁
 @TotalPage int output      --返回總頁數
as
begin

  Begin Tran --開始事務

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

  --計算總記錄數

  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--計算總記錄數

  --計算總頁數
  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

  --處理頁數超出范圍情況
  if @PageIndex<=0
    Set @pageIndex = 1

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

   --處理開始點和結束點
  Declare @StartRecord int
  Declare @EndRecord int

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

  --繼續合成sql語句
  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 ---返回記錄總數
   End
end
