Vorgehensweise bei der Paginierung in SQL Server 2008

34

können Sie versuchen, so etwas wie

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)

ich diesen Code dosn't Arbeit. Hast du diesen Code getestet? (Er sollte die "PageNumbers" -Tabelle durch die "@Table" ersetzen. – RockOnGom

@zeitgeist, verwendet ein CTE namens PageNumbers. Haben Sie den Code getestet? –

Sie können ROW_NUMBER() verwenden:

Liefert die laufende Nummer einer Zeile innerhalb einer Partition eines Ergebnismenge in jeder Partition für die erste Zeile, beginnend bei 1.

Beispiel:

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;

Diese beiden Artikel enthalten die Informationen, die ich vor einiger Zeit nützlich gefunden:

1) Erstellen Blinddaten

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) jetzt die Lösung GILT.

In diesem Fall wird EMPID als eindeutige und sortierte Spalte angenommen.

Off-Kurs, werden Sie es eine andere Spalte anwenden ...

DECLARE @pageSize INT = 20 

SELECT * FROM (

SELECT *, PageNumber = CEILING(CAST(EMPID AS FLOAT)/@pageSize) 
FROM #employee 
) MyQuery 

WHERE MyQuery.PageNumber = 1

Schöne Annäherung, aber das Hinzufügen einer neuen Spalte könnte ein Overhead sein –

SQL Server 2012 bietet Paginierung-Funktionalität (siehe http://www.codeproject.com/Articles/442503/New-features-for-database-developers-in-SQL-Server)

In SQL2008 können Sie es auf diese Weise tun:

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! Es funktioniert und skaliert konsequent.

Dies sind meine Lösung für das Auslagern des Ergebnisses der Abfrage in SQL Server-Seite. Ich habe das Konzept der Filterung und Ordnung um mit einer Spalte hinzugefügt. Es ist sehr effizient, wenn Sie in Gridview paging und filtern und bestellen.

Bevor Sie testen, müssen Sie eine Beispieltabelle erstellen und eine Zeile in diese Tabelle einfügen: (In der Praxis müssen Sie die Where-Klausel in Ihrem Tabellenfeld ändern und vielleicht haben Sie eine Unteranfrage im Hauptteil von select)

In SQL Server 2008 können Sie das CTE-Konzept verwenden.Aus diesem Grund habe ich zwei Arten von Abfrage für SQL Server 2008+

geschrieben - SQL Server 2008+

DECLARE @PageNumber Int = 1200

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.
