通過存儲過程來進行DataGrid自動分頁，效率很高，可以進行百萬和千萬級的分頁

自己通過50萬條記錄測試，翻至任何頁，需時小于一秒

呵呵，僅供自己以后察看使用，所以代碼寫的不很規范

所需的存儲過程如下：

CREATE?PROCEDURE?UP_GetRecordByPage
????@tblName??????varchar(255),???????--?表名
????@fldName??????varchar(255),???????--?主鍵字段名
????@PageSize?????int?=?10,???????????--?頁尺寸
????@PageIndex????int?=?1,????????????--?頁碼
????@IsReCount????bit?=?1,????????????--?返回記錄總數,?非?0?值則返回
????@OrderType????bit?=?0,????????????--?設置排序類型,?非?0?值則降序
????@strWhere?????varchar(1000)?=?''??--?查詢條件?(注意:?不要加?where)
AS

declare?@strSQL???varchar(6000)???????--?主語句
declare?@strTmp???varchar(100)????????--?臨時變量
declare?@strOrder?varchar(400)????????--?排序類型

if?@OrderType?!=?0

????set?@strTmp?=?'<(select?min'

????????+?@strOrder?+?')?as?tblTmp)?and?'?+?@strWhere?+?'?'?+?@strOrder

if?@PageIndex?=?1

end

if?@IsReCount?!=?0
????set?@strSQL?=?'select?count(*)?as?Total?from?['?+?@tblName?+?']'+'?where?'?+?@strWhere
