導讀:1建站知識這兩天幫朋友修改一個項目，看到一個存儲過程，感覺性能非常高。于是，整合自己以前搜集的比較好的存儲過程，高端網站建設網站優化seo培訓。

（下面的代碼原來我想用折疊的代碼的，但是在google里面老是添加不了折疊的代碼，所以就整屏的貼出來了，望大家不要見外。） 朋友的比較好的存儲過程。優點是：性能非常的高，每次查詢都是根據ID查詢，每次都是對一半的數據進行分頁。缺點是：當有多個排序條件時，分頁數據顯示會出現問題。（該問題在第二個網友的分頁存儲過程中有解決的方法）。

復制代碼 代碼如下:

set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go ALTER PROCEDURE [dbo].[proc_page] ( @tblName nvarchar(200), ----要顯示的表或多個表的連接lihu @fldName nvarchar(500) = '*', ----要顯示的字段列表 @pageSize int = 10, ----每頁顯示的記錄個數 @page int = 1, ----要顯示那一頁的記錄 @fldSort nvarchar(200) = null, ----排序字段列表或條件 @Sort bit = 0, ----排序方法，0為升序，1為降序(如果是多字段排列Sort指代最后一個排序字段的排列順序(最后一個排序字段不加排序標記)--程序傳參如：' SortA Asc,SortB Desc,SortC ') @strCondition nvarchar(1000), ----查詢條件,不需where @ID nvarchar(150), ----主表的主鍵 @Dist bit = 0, ----是否添加查詢字段的 DISTINCT 默認0不添加/1添加 @pageCount int = 1 output, ----查詢結果分頁后的總頁數 @Counts int = 1
