我有一张桌子：

+---------+--------------------+--------------------------+

并尝试生成看起来像这样的数据

+---------+--------------------------+----------+---------------+-----------+----------------------+----------+
| imd_id  |      TopFirstPlan       | TopFirst | TopSecondPlan | TopSecond |    TopThirdPlan     | TopThird |
+---------+--------------------------+----------+---------------+-----------+----------------------+----------+
| 1111005 | Medicaid Illinois (Idpa) | 0.78     | Self Pay      | 0.05      | Tricare North Region | 0.04     |
| 1111531 | MEDICAID ALABAMA (AL)    | 0.5      | Self Pay      | 0.04      | Bcbs Federal         | 0.02     |
+---------+--------------------------+----------+---------------+-----------+----------------------+----------+

请注意，创建 TOPFIRST、TOP SECOND、TOP THIRD 的方式是相应的Total TRx per Plan除以该特定 IMD_ID 的计划总和。

到目前为止，我有这个：

 select distinct a.imd_id,'topone'=
    (select top 1 totalrxperplan 
        from book1 b
      where b.imd_id =  a.imd_id)/
      (select SUM(totalrxperplan) 
        from book1 b
        where b.imd_id = a.imd_id)
      ,'topplan2'=
      (select top 1 xifinplanname 
        from book1 b
      where b.imd_id =  a.imd_id)
from book1 a
order by 1 asc

此查询将返回：

+---------+--------------------------+----------+
| imd_id  |      TopFirstPlan1       | TopFirst |
+---------+--------------------------+----------+
| 1111005 | Medicaid Illinois (Idpa) | 79%      |
| 1111531 | MEDICAID ALABAMA (AL)    | 53%      |
+---------+--------------------------+----------+

但我需要添加其他列。

请注意，我们将ignore the plan name where it is 0

CREATE TABLE #x(imd_id INT, totalrxperplan FLOAT, xifinplanname NVARCHAR(64));

INSERT #x VALUES
(1111005,397.1556 ,'Medicaid Illinois (Idpa)'),

现在查询：

WITH cte1(id,pn,s) AS 
(
    SELECT imd_id, xifinplanname, 
      ROUND(totalrxperplan/SUM(totalrxperplan) OVER (PARTITION BY imd_id),2,1)
    FROM #x WHERE xifinplanname <> '0'
),
cte2(id,pn,s,rn) AS 
(
    SELECT id,pn,s,ROW_NUMBER() OVER (PARTITION BY id ORDER BY s DESC)
    FROM cte1
)
SELECT 
  id, 
  TopFirstPlan  = MAX(CASE WHEN rn = 1 THEN pn END),
  TopFirst      = MAX(CASE WHEN rn = 1 THEN s  END),
  TopSecondPlan = MAX(CASE WHEN rn = 2 THEN pn END),
  TopSecond     = MAX(CASE WHEN rn = 2 THEN s  END),
  TopThirdPlan  = MAX(CASE WHEN rn = 3 THEN pn END),
  TopThird      = MAX(CASE WHEN rn = 3 THEN s  END)
FROM cte2 
WHERE rn <= 3
GROUP BY id;

如果我的假设是正确的，即输出数字与您的不匹配，因为您想在总数中甚至包含“0”计划，而不是在结果中，那么您可以移动 where 子句：

WITH cte1(id,pn,s) AS 
(
    SELECT imd_id, xifinplanname, 
      ROUND(totalrxperplan/SUM(totalrxperplan) OVER (PARTITION BY imd_id), 2, 1)
    FROM #x -- < -- removed where clause from here
),
cte2(id,pn,s,rn) AS 
(
    SELECT id,pn,CONVERT(DECIMAL(3,2), s),ROW_NUMBER() OVER 
      (PARTITION BY id ORDER BY s DESC)
    FROM cte1 WHERE pn <> '0' -- <-- moved where clause here
)
SELECT 
  id, 
  TopFirstPlan  = MAX(CASE WHEN rn = 1 THEN pn END),
  TopFirst      = MAX(CASE WHEN rn = 1 THEN s  END),
  TopSecondPlan = MAX(CASE WHEN rn = 2 THEN pn END),
  TopSecond     = MAX(CASE WHEN rn = 2 THEN s  END),
  TopThirdPlan  = MAX(CASE WHEN rn = 3 THEN pn END),
  TopThird      = MAX(CASE WHEN rn = 3 THEN s  END)
FROM cte2 
WHERE rn <= 3
GROUP BY id;

如果我理解正确，关键是通过每个 imd_id 中的总数来枚举组。您可以使用 windows 函数 row_number() 来执行此操作。

最终查询类似于：

select imd_id,
       max(case when therank = 1 then plan_name end) as firstplan,
       max(case when therank = 1 then tot/imd_tot end) as firstplan_ratio,
       ...
from (select t.*, row_number() over (partition by imd_id order by tot desc) as therank,
             sum(tot) over (partition by imd_id) as imd_tot
      from (select imd_id  plan_name, sum(total_trx_per_plan) as tot
            from t
            group by imd_id  plan_name
           ) t
     ) t
group by imd_id

我不确定 Aaron 的总数，而不是每个 ID 的总数，是 OP 想要的，所以这是我的建议，基本上是 Aaron 建议的，但分数值不同：

更新以纠正错误副本，并考虑“0”规则。

with R1 as (
  select
    imd_id,
    [plan name],
    1e0*[Total TRx per Plan]/sum([Total TRx per Plan]) over (partition by imd_id) as pct,
    row_number() over (
      partition by imd_id
      order by case when [plan name] = '0' then -1 else [Total TRx per Plan] end desc
    ) as rn
  from @Test
) 
  select
    imd_id,
    max(case when rn=1 then [plan name] end) as TopFirstPlan,
    max(case when rn=1 then pct end) as TopFirst,
    max(case when rn=2 then [plan name] end) as TopSecondPlan,
    max(case when rn=2 then pct end) as TopSecond,
    max(case when rn=3 then [plan name] end) as TopThirdPlan,
    max(case when rn=3 then pct end) as TopThird
  from R1
  where rn <= 3
  group by imd_id
  order by imd_id

我想出了这样的查询：

WITH totals AS (
  SELECT imd_id, sum(t_trx_per_plan) AS ttl
    FROM plans
   GROUP BY imd_id),
ranks(imd_id,t_trx_per_plan,plan_name,prc,rank) AS (
  SELECT p.imd_id,p.t_trx_per_plan,p.plan_name,
    CAST(p.t_trx_per_plan / t.ttl * 100 AS NUMERIC(5,2)) AS prc,
    rank() OVER (PARTITION BY p.imd_id
        ORDER BY (p.t_trx_per_plan / t.ttl * 100) DESC) AS rank
    FROM plans p
    JOIN totals t ON t.imd_id = p.imd_id
   WHERE p.plan_name != '0')
SELECT
    ttl.imd_id,
    f.plan_name AS "FirstPlan",f.prc AS "First",
    s.plan_name AS "SecondPlan",s.prc AS "Second",
    t.plan_name AS "ThirdPlan",t.prc AS "Third"
  FROM totals ttl
  LEFT JOIN ranks f ON f.imd_id = ttl.imd_id AND f.rank = 1
  LEFT JOIN ranks s ON s.imd_id = ttl.imd_id AND s.rank = 2
  LEFT JOIN ranks t ON t.imd_id = ttl.imd_id AND t.rank = 3;

第一个 CTEtotals给出了imd_id每个计划的总交易量列表。第二个CTEranks是排名计划。请注意，我使用了rank()函数，如果计划每个计划具有相同数量的事务，它将产生相同的排名。如果要正确处理此类情况，则需要使用row_number()窗口函数并在子句中添加额外的ORDER BY列OVER，唯一的可能是使用：

row_number() OVER (PARTITION BY p.imd_id
    ORDER BY (p.t_trx_per_plan / t.ttl * 100) DESC, p.plan_name) AS rank

您可以在此处检查输出。
