復制代碼 代碼如下:

Declare @ID int
Declare @MoveRecords int

--@CurrentPage和@PageSize是傳入參數
Set @MoveRecords=@CurrentPage * @PageSize+1

--下面兩行實現快速滾動到我們要取的數據的行，并把ID記錄下來
Set Rowcount @MoveRecords
Select @ID=ID from Table1 Order by ID

Set Rowcount @PageSize
--最恨為了減少麻煩使用*了，但是在這里為了說明方便，暫時用一下
Select * From Table1 Where ID>=@ID Order By ID
Set Rowcount 0

復制代碼 代碼如下:

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
Create PROCEDURE [dbo].[Tag_Page_Name_Select]
-- 傳入最大顯示紀錄數和當前頁碼
@MaxPageSize int,
@PageNum int,
-- 設置一個輸出參數返回總紀錄數供分頁列表使用
@Count int output
AS
BEGIN
SET NOCOUNT ON;

DECLARE
-- 定義排序名稱參數
@Name nvarchar(50),
-- 定義游標位置
@Cursor int
-- 首先得到紀錄總數
Select @Count = count(tag_Name)
FROM [viewdatabase0716].[dbo].[view_tag];
-- 定義游標需要開始的位置
Set @Cursor = @MaxPageSize*(@PageNum-1)+1
-- 如果游標大于紀錄總數將游標放到最后一頁開始的位置
IF @Cursor > @Count
BEGIN
-- 如果最后一頁與最大每次紀錄數相等，返回最后整頁
IF @Count % @MaxPageSize = 0
BEGIN
IF @Cursor > @MaxPageSize
Set @Cursor = @Count - @MaxPageSize + 1
ELSE
Set @Cursor = 1
END
-- 否則返回最后一頁剩下的紀錄
ELSE
Set @Cursor = @Count - (@Count % @MaxPageSize) + 1
END
-- 將指針指到該頁開始
Set Rowcount @Cursor
-- 得到紀錄開始的位置
Select @Name = tag_Name
FROM [viewdatabase0716].[dbo].[view_tag]
orDER BY tag_Name;
-- 設置開始位置
Set Rowcount @MaxPageSize
-- 得到該頁紀錄
Select *
From [viewdatabase0716].[dbo].[view_tag]
Where tag_Name >= @Name
order By tag_Name

Set Rowcount 0
END
