SQL Server 千萬數量級 分頁 預存程序

隨著資訊時代的發展資訊系統的使用越來越多，資訊量越來越大；當資訊量越來越大，這在資料展示，特別是報表這塊對系統展現效率要求越來越高，對於千萬級資料量的展示必須得使用分頁來展示。
If object_id('SP_Pagination')is not null
drop proc SP_Pagination
go
Create PROCEDURE SP_Pagination

** 千萬數量級分頁預存程序 **

參數說明:
.Tables :表名稱,視圖(試圖這邊目前還有點小問題)
.PrimaryKey :主關鍵字
.Sort :排序語句，不帶Order By 比如：NewsID Desc,OrderRows Asc
.CurrentPage :當前頁碼
.PageSize :分頁尺寸
.Filter :過濾語句，不帶Where
.Group :Group語句,不帶Group By

下面是在資料庫查詢分析器裡面怎麼調用這個預存程序的執行個體。如圖所示為Traffic_Sites原表查詢的結果集。以Traffic_Sites表為例執行分頁預存程序指令碼：exec SP_Pagination 'Traffic_Sites','Id','Id asc',1,5,'*','',''執行上述SQL結果如圖所示：
