SQL 视图的查询修复

Question

请使用以下临时 table 和数据集作为参考。使用以下数据集，我正在尝试创建一个新数据集。

    DECLARE @Temp TABLE 
    (
        year_month int,
        Vuid int,
        Puid int,
        ac_cd varchar(20),
        sub_ac_cd varchar(20),
        jdg_sts varchar(20),
        voy_pl_usd int
    )

insert into @temp values(202005,1,1,'M01180','0','S',30)
insert into @temp values(202006,1,1,'M01180','0','P',20)
insert into @temp values(202007,1,1,'M01180','0','M',40)
insert into @temp values(202005,1,2,'M01180','0','S',15)
insert into @temp values(202006,1,2,'M01180','0','P',10)
insert into @temp values(202007,1,2,'M01180','0','P',15)
insert into @temp values(202005,2,1,'M01180','0','S',60)
insert into @temp values(202006,2,1,'M01180','0','P',15)
insert into @temp values(202007,2,1,'M01180','0','M',10)
insert into @temp values(202005,2,2,'M01180','0','S',25)
insert into @temp values(202006,2,2,'M01180','0','P',25)
insert into @temp values(202007,2,2,'M01180','0','A',30)
insert into @temp values(202005,1,1,'M01170','0','A',20)
insert into @temp values(202006,1,1,'M01170','0','A',20)
insert into @temp values(202007,1,1,'M01170','0','A',35)
insert into @temp values(202005,1,2,'M01170','0','P',15)
insert into @temp values(202006,1,2,'M01170','0','S',5)
insert into @temp values(202007,1,2,'M01170','0','M',5)
insert into @temp values(202005,2,1,'M01170','0','S',5)
insert into @temp values(202006,2,1,'M01170','0','P',15)
insert into @temp values(202007,2,1,'M01170','0','P',20)
insert into @temp values(202005,2,2,'M01170','0','S',5)
insert into @temp values(202006,2,2,'M01170','0','P',15)
insert into @temp values(202007,2,2,'M01170','0','M',10)

输出数据集应如下所示：

在上图中，Port cost 是 VOY_PL_USD 列与基于 voy_uid、pc_uid、ac_cd('M01180') & sub_ac_cd 列。同样，Agent fee 是 VOY_PL_USD 列与基于 voy_uid、pc_uid、ac_cd('M01170') 和 [=19 的最新 jdg_sts 列值连接的 SUM =] 列。根据最新的Year_month字段选择最新的记录。

请注意：我的查询将放在一个视图中。请告诉我如何实现它..

数据集：

这是我写的：

SELECT TOP (1) WITH TIES 
                            Vuid
                            ,Puid
                            ,ac_cd
                            ,sub_ac_cd                          
                            ,CAST(SUM(VOY_PL_USD) OVER (PARTITION BY Vuid, Puid, ac_cd, sub_ac_cd) AS VARCHAR(12)) + jdg_sts AS [cost]
    FROM @Temp
    ORDER BY ROW_NUMBER() OVER (PARTITION BY Vuid, Puid, ac_cd, sub_ac_cd ORDER BY year_month DESC)

试试这个：

SELECT Vuid
      ,Puid
      ,CAST(MAX([Port Cost]) AS VARCHAR(12)) + MAX(CASE WHEN [Pro Cost Suffix] = 1 THEN [jdg_sts] END) AS  [Port Cost]
      ,CAST(MAX([Agent Fee]) AS VARCHAR(12)) +  MAX(CASE WHEN [Agent Fee Suffix] = 1 THEN [jdg_sts] END) AS  [Agent Fee]
FROM
(
    SELECT Vuid, Puid
          ,SUM(CASE WHEN ac_cd = 'M01180' THEN VOY_PL_USD END) OVER (PARTITION BY Vuid, Puid, ac_cd, sub_ac_cd)
          ,SUM(CASE WHEN ac_cd = 'M01170' THEN VOY_PL_USD END) OVER (PARTITION BY Vuid, Puid, ac_cd, sub_ac_cd)       
          ,CASE WHEN ac_cd = 'M01180' THEN DENSE_RANK() OVER (PARTITION BY Vuid, Puid, sub_ac_cd ORDER BY Year_month DESC) END
          ,CASE WHEN ac_cd = 'M01170' THEN DENSE_RANK() OVER (PARTITION BY Vuid, Puid, sub_ac_cd ORDER BY Year_month DESC) END
          ,jdg_sts
     FROM Temp
) DS (Vuid, Puid, [Port Cost], [Agent Fee], [Pro Cost Suffix], [Agent Fee Suffix], [jdg_sts])
GROUP BY Vuid
        ,Puid
ORDER BY Vuid
        ,Puid;
