如何在SQL Server 2008中进行分页
你如何在SQL Server 2008中进行分页?
你可以尝试类似的东西
DECLARE @Table TABLE( Val VARCHAR(50) ) DECLARE @PageSize INT, @Page INT SELECT @PageSize = 10, @Page = 2 ;WITH PageNumbers AS( SELECT Val, ROW_NUMBER() OVER(ORDER BY Val) ID FROM @Table ) SELECT * FROM PageNumbers WHERE ID BETWEEN ((@Page - 1) * @PageSize + 1) AND (@Page * @PageSize)
你可以使用ROW_NUMBER() :
返回结果集分区内的行的序号,从1开始,为每个分区中的第一行。
例:
WITH CTEResults AS ( SELECT IDColumn, SomeField, DateField, ROW_NUMBER() OVER (ORDER BY DateField) AS RowNum FROM MyTable ) SELECT * FROM CTEResults WHERE RowNum BETWEEN 10 AND 20;
SQL Server 2012提供了分页function(请参阅http://www.codeproject.com/Articles/442503/New-features-for-database-developers-in-SQL-Server )
在SQL2008中,你可以这样做:
declare @rowsPerPage as bigint; declare @pageNum as bigint; set @rowsPerPage=25; set @pageNum=10; With SQLPaging As ( Select Top(@rowsPerPage * @pageNum) ROW_NUMBER() OVER (ORDER BY ID asc) as resultNum, * FROM Employee ) select * from SQLPaging with (nolock) where resultNum > ((@pageNum - 1) * @rowsPerPage)
Prooven! 它的工作和规模一贯。
这两篇文章包含了我以前觉得有用的信息:
1)创build虚拟数据
CREATE TABLE #employee (EMPID INT IDENTITY, NAME VARCHAR(20)) DECLARE @id INT = 1 WHILE @id < 200 BEGIN INSERT INTO #employee ( NAME ) VALUES ('employee_' + CAST(@id AS VARCHAR) ) SET @id = @id + 1 END
2)现在申请解决scheme。
这种情况下假设EMPID是唯一的,并sorting列。
当然,你会用它不同的列…
DECLARE @pageSize INT = 20 SELECT * FROM ( SELECT *, PageNumber = CEILING(CAST(EMPID AS FLOAT)/@pageSize) FROM #employee ) MyQuery WHERE MyQuery.PageNumber = 1
这些是我在SQL服务器端分页查询结果的解决scheme。 我已经添加了一个列的过滤和sorting的概念。 当你在GridView中进行分页和过滤和sorting的时候,它是非常高效的。
在testing之前,您必须创build一个样本表并在该表中插入一些行(在现实世界中,您必须更改Where子句考虑您的表字段,并且可能在select的主要部分中有一些联接和子查询)
Create Table VLT ( ID int IDentity(1,1), Name nvarchar(50), Tel Varchar(20) ) GO Insert INTO VLT VALUES ('NAME' + Convert(varchar(10),@@identity),'FAMIL' + Convert(varchar(10),@@identity)) GO 500000
在SQL Server 2008中,您可以使用CTE概念。 因此,我写了SQL Server 2008+的两种types的查询
– SQL Server 2008+
DECLARE @PageNumber Int = 1200 DECLARE @PageSize INT = 200 DECLARE @SortByField int = 1 --The field used for sort by DECLARE @SortOrder nvarchar(255) = 'ASC' --ASC or DESC DECLARE @FilterType nvarchar(255) = 'None' --The filter type, as defined on the client side (None/Contain/NotContain/Match/NotMatch/True/False/) DECLARE @FilterValue nvarchar(255) = '' --The value the user gave for the filter DECLARE @FilterColumn int = 1 --The column to wich the filter is applied, represents the column number like when we send the information. SELECT Data.ID, Data.Name, Data.Tel FROM ( SELECT ROW_NUMBER() OVER( ORDER BY CASE WHEN @SortByField = 1 AND @SortOrder = 'ASC' THEN VLT.ID END ASC, CASE WHEN @SortByField = 1 AND @SortOrder = 'DESC' THEN VLT.ID END DESC, CASE WHEN @SortByField = 2 AND @SortOrder = 'ASC' THEN VLT.Name END ASC, CASE WHEN @SortByField = 2 AND @SortOrder = 'DESC' THEN VLT.Name END ASC, CASE WHEN @SortByField = 3 AND @SortOrder = 'ASC' THEN VLT.Tel END ASC, CASE WHEN @SortByField = 3 AND @SortOrder = 'DESC' THEN VLT.Tel END ASC ) AS RowNum ,* FROM VLT WHERE ( -- We apply the filter logic here CASE WHEN @FilterType = 'None' THEN 1 -- Name column filter WHEN @FilterType = 'Contain' AND @FilterColumn = 1 AND ( -- In this case, when the filter value is empty, we want to show everything. VLT.ID LIKE '%' + @FilterValue + '%' OR @FilterValue = '' ) THEN 1 WHEN @FilterType = 'NotContain' AND @FilterColumn = 1 AND ( -- In this case, when the filter value is empty, we want to show everything. VLT.ID NOT LIKE '%' + @FilterValue + '%' OR @FilterValue = '' ) THEN 1 WHEN @FilterType = 'Match' AND @FilterColumn = 1 AND VLT.ID = @FilterValue THEN 1 WHEN @FilterType = 'NotMatch' AND @FilterColumn = 1 AND VLT.ID <> @FilterValue THEN 1 -- Name column filter WHEN @FilterType = 'Contain' AND @FilterColumn = 2 AND ( -- In this case, when the filter value is empty, we want to show everything. VLT.Name LIKE '%' + @FilterValue + '%' OR @FilterValue = '' ) THEN 1 WHEN @FilterType = 'NotContain' AND @FilterColumn = 2 AND ( -- In this case, when the filter value is empty, we want to show everything. VLT.Name NOT LIKE '%' + @FilterValue + '%' OR @FilterValue = '' ) THEN 1 WHEN @FilterType = 'Match' AND @FilterColumn = 2 AND VLT.Name = @FilterValue THEN 1 WHEN @FilterType = 'NotMatch' AND @FilterColumn = 2 AND VLT.Name <> @FilterValue THEN 1 -- Tel column filter WHEN @FilterType = 'Contain' AND @FilterColumn = 3 AND ( -- In this case, when the filter value is empty, we want to show everything. VLT.Tel LIKE '%' + @FilterValue + '%' OR @FilterValue = '' ) THEN 1 WHEN @FilterType = 'NotContain' AND @FilterColumn = 3 AND ( -- In this case, when the filter value is empty, we want to show everything. VLT.Tel NOT LIKE '%' + @FilterValue + '%' OR @FilterValue = '' ) THEN 1 WHEN @FilterType = 'Match' AND @FilterColumn = 3 AND VLT.Tel = @FilterValue THEN 1 WHEN @FilterType = 'NotMatch' AND @FilterColumn = 3 AND VLT.Tel <> @FilterValue THEN 1 END ) = 1 ) AS Data WHERE Data.RowNum > @PageSize * (@PageNumber - 1) AND Data.RowNum <= @PageSize * @PageNumber ORDER BY Data.RowNum GO
而SQL Server 2008+中的第二个CTE解决scheme
