2.1分頁存儲過程

2.1.1簡介

2.1.2分頁存儲過程代碼

以下代碼是網上找的分頁存儲過程，我是在原存儲過程的基礎上加了一個@IsCount bit = 0, 主要是用來返回紀錄總數，當爲非0值時返回。下面註釋部分是原作者的測試部分。我在本機sql server 2005上的測試是在10000011紀錄中查詢第100000頁，每頁10條紀錄按升序和降序時間均爲0.38秒，測試語法如下：exec GetRecordFromPage tbl_Briefness,I_BriefnessID,10,100000，其中在tbl_Briefness表I_BriefnessID字段上建立了索引。

/**//*
  經測試，在14483461 條記錄中查詢第100000 頁，每頁10 條記錄按升序和降序第一次時間均爲0.47 秒，第二次時間均爲0.43 秒，測試語法如下：
  exec GetRecordFromPage news,newsid,10,100000
  news 爲表名, newsid 爲關鍵字段, 使用時請先對newsid 建立索引。

  函數名稱: GetRecordFromPage
  函數功能: 獲取指定頁的數據
  參數說明: @tblName      包含數據的表名
           @fldName      關鍵字段名
           @PageSize     每頁記錄數
           @PageIndex    要獲取的頁碼
           @OrderType    排序類型, 0 - 升序, 1 - 降序
           @strWhere     查詢條件(注意: 不要加where)

2.3千萬級數據分頁實現

2.3.1簡介

這次分頁我是用Gridview來實現的，測試時間沒算，但基本上從10000011紀錄中一次查詢25條紀錄，在10萬頁以內，時間花費 在1秒以內。使用其他控件比如DataGrid，DataList或者DataReapter應該花費的時間更短。

2.3.2適用對象

服務器端控件Gridview，DataGrid，DataList，DataReapter等數據綁定控件

2.3.3分頁實現

分頁效果圖如下：

 

前臺代碼如下：

後臺代碼如下：
