このサイトをググって検索しましたが、何も機能していないようです。私が見つけたすべての構文が気に入らないようです。誰でも助けることができますか？作成した topRange 変数と bottomRange 変数を使用したい

ALTER PROCEDURE [dbo].[getTopFantasyPlayersByPositionSeason]
    @top int,
    @position varchar(3),
    @topRange int,
    @bottomRange int
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    IF @position = 'QB' OR @position = 'RB' OR @position = 'WR' OR @position = 'TE' OR @position = 'K' OR @position = 'D' OR @position = 'TE'
        BEGIN
            SELECT TOP (@top) *
            FROM nflPassers_season
            WHERE position=@position AND points > 0
            ORDER BY points DESC
        END

END

SQL 2012 より前の基本的なページネーション:

SELECT *
FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY points DESC) AS RowRank
      FROM YourTable
      )AS sub
WHERE Rowrank BETWEEN @Variable1 AND @Variable2

いくつかのグループごと、つまりプレーヤーごとに結果の範囲が必要な場合は、次PARTITION BYのように追加できROW_NUMBER()ます。

SELECT *
FROM (SELECT *, ROW_NUMBER() OVER (PARTITION BY SomeField ORDER BY points DESC) AS RowRank
      FROM YourTable
      WHERE position = @position
        AND points > 0
      ) AS sub
WHERE Rowrank BETWEEN @Variable1 AND @Variable2

PARTITION BYこれにより、節内の各項目のランキングが 1 から開始されます。
