SQL Server 2008でページネーションを行う方法

SQL Server 2008でページネーションをどのように行いますか？

あなたは次のようなものを試すことができます

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)

ROW_NUMBER（） を使用できます。

結果セットのパーティション内の行の連続番号を返します。各パーティションの最初の行の1から始まります。

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はページネーション機能を提供します（ http://www.codeproject.com/Articles/442503/New-features-for-database-developers-in-SQL-Server を参照）

SQL2008では、次の方法で実行できます。

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)

証明済み！一貫して機能し、スケーリングします。

1）ダミーデータの作成

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）今すぐソリューションを適用してください。

このケースでは、EMPIDが一意でソートされた列であると想定しています。

コース外では、別の列に適用します...

DECLARE @pageSize INT = 20

SELECT * FROM (

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

WHERE MyQuery.PageNumber = 1

これらは、SQLサーバー側でクエリの結果をページングするための私のソリューションです。フィルタリングと並べ替えの概念を1列で追加しました。 Gridviewでページング、フィルタリング、順序付けをしているときに非常に効率的です。

テストする前に、サンプルテーブルを1つ作成し、このテーブルに行を挿入する必要があります（実際には、テーブルフィールドを考慮してWhere句を変更する必要があり、selectの主要部分に結合とサブクエリが含まれる場合があります）

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

SQL Server 2008では、CTEコンセプトを使用できます。そのため、SQL Server 2008+用に2種類のクエリを作成しました

少なくともSQL 2005で機能する別のソリューションは、SELECTサブクエリとORDER BY句でTOPを使用することです。

簡単に言うと、ページごとに10行のページ2行を取得することは、最初の20行の最後の10行を取得することと同じです。これは、ASCを使用して再度注文する前に、ASCの順序で最初の20行を取得し、次にDESCの順序で最初の10行を取得することに変換されます。

例：ページごとに3行のページ2行を取得する

create table test(id integer);
insert into test values(1),(2),(3),(4),(5),(6),(7),(8),(9),(10);

select * 
    from (
        select top 2 * 
            from (
                select  top (4) * 
                    from test 
                    order by id asc) tmp1
            order by id desc) tmp1 
    order by id asc
