SQL Server将具有多个条件的列总和转换为相同条件数据的新列

Question

我有一张高尔夫数据表。对于给定锦标赛的每一轮，每个高尔夫球手都有一个最终得分（round_score 列）。我想将每个高尔夫球手的所有回合得分相加并将其存储在 final_score 列中。我希望该 final_score 数字对于该高尔夫球手参加锦标赛的所有行都保持不变。但它为每一行产生不同的数字。

finalscore_points 列是一个公式：final_score * -3。所以我当然不希望这个数字也改变，对于给定锦标赛中的高尔夫球手的所有行。

例如：如果高尔夫球手 A 在第 1-4 轮中的 round_score 总和 = -2，那么我希望每行中的 final_score 列（按轮次、锦标赛 ID 和年份划分）将 -2 作为其值。

我该怎么做呢？

    Select player_id, full_name, [year] ,tournament_id, [round], 
    round_score, sum(round_score) as final_score, sum(round_score) * -3 as 
    finalscore_points 
    From v_temptable6
    Group By player_id, full_name, [year] ,tournament_id, [round], 
    round_score
    Order by [year], tournament_id, full_name, [round], round_score

Answer 1

为什么要对 round_score 进行分组也从 group by 子句中删除 Round Score 并在选择中添加MIN(round_score)

Select player_id, full_name, [year] ,tournament_id, [round], MIN(round_score), sum(round_score) as final_score, sum(round_score) * -3 finalscore_points From v_temptable6 Group By player_id, full_name, [year] ,tournament_id, [round] Order by [year], tournament_id, full_name, [round], round_score

Answer 2

您可以尝试以下查询。这里的RoundScore 是玩家每轮Tournament 的SUM。

SELECT   *,(RoundScore * -3) AS FinalScore 
FROM     ( 
            SELECT   player_id, 
                    full_name, 
                    [year] , 
                    tournament_id, 
                    [round], 
                    round_score, 
                    Sum(round_score) OVER(PARTITION BY player_id,tournament_id ORDER BY player_id) AS RoundScore 
            FROM     v_temptable6 
          ) T 
ORDER BY [year], 
         tournament_id, 
         full_name, 
         [round]

示例示例

DECLARE @TABLE TABLE(Player_Id VARCHAR(100), Full_Name VARCHAR(100), [Year] INT, tournament_id INT, Round int, Round_Score INT)
INSERT INTO @TABLE
SELECT 'C3CCE201-9176-4910-9916-253FCFBE7899','AB',2013,1,1,3
INSERT INTO @TABLE
SELECT 'C3CCE201-9176-4910-9916-253FCFBE7899','AB',2013,1,2,3    

INSERT INTO @TABLE
SELECT '51FB1D63-C925-4E69-B89B-2566271A8C8C','AC',2013,1,1,7

INSERT INTO @TABLE
SELECT '51FB1D63-C925-4E69-B89B-2566271A8C8C','AC',2013,1,2,5

INSERT INTO @TABLE
SELECT 'EE6036AF-3C74-4F34-94CE-7695473ADB04','BC',2013,1,1,-2

INSERT INTO @TABLE
SELECT 'EE6036AF-3C74-4F34-94CE-7695473ADB04','BC',2013,1,2,2

INSERT INTO @TABLE
SELECT 'EE6036AF-3C74-4F34-94CE-7695473ADB04','BC',2013,1,3,-1

INSERT INTO @TABLE
SELECT 'EE6036AF-3C74-4F34-94CE-7695473ADB04','BC',2013,1,4,7



SELECT   *,(RoundScore * -3) AS FinalScore 
FROM     ( 
            SELECT   player_id, 
                    full_name, 
                    [year] , 
                    tournament_id, 
                    [round], 
                    round_score, 
                    Sum(round_score) OVER(PARTITION BY player_id,tournament_id ORDER BY player_id) AS RoundScore 
            FROM     @TABLE 
          ) T 
ORDER BY [year], 
         tournament_id, 
         full_name
