sql - 排名显示所有用户良好。但是如何显示一个用户的排名呢？

Question

我有这个 SQL 查询:

SELECT 
    DENSE_RANK() OVER (ORDER BY s.rows DESC) AS Ranks,
    Territory, TM_Name,
    COALESCE(g.rows, 0) AS RXCount, 
    COALESCE(s.rows, 0) AS DelCounts,
    COALESCE(nd.rows, 0) AS NotDeliveredCount,
    COALESCE(trgt.rows, 0) AS Target,
    e.TM_Emp_Id
FROM 
    tblEmployee e
LEFT JOIN
    (SELECT EmpCode, SUM(RxGenerate) AS rows 
     FROM tbl_RX 
     GROUP BY EmpCode) g ON g.EmpCode = e.TM_Emp_Id
LEFT JOIN
    (SELECT EmpCode, SUM(MedToPCount) AS rows 
     FROM tbl_MedicinToPatient 
     WHERE Status = 'Delivered' 
     GROUP BY EmpCode) s ON s.EmpCode = e.TM_Emp_Id
LEFT JOIN
    (SELECT EmpCode, COUNT(*) AS rows 
     FROM tbl_MedicinToPatient 
     WHERE Status != 'Delivered' 
     GROUP BY EmpCode) nd ON nd.EmpCode = e.TM_Emp_Id
LEFT JOIN
    (SELECT 
         EmpCode, CurrentTarget AS rows,   
         CreatedDate, RankOrder, T.PreviousTarget 
     FROM
         (SELECT
              EmpCode, CurrentTarget, CreatedDate,PreviousTarget,
              RANK() OVER (PARTITION BY EmpCode ORDER BY CreatedDate DESC) RankOrder
          FROM
              tbl_Target) T 
     WHERE 
         RankOrder = 1) trgt ON trgt.EmpCode = e.TM_Emp_Id

它返回所需的输出。这对于每个用户来说都是完美计算排名的。但是当我在查询末尾添加 where 条件时，例如:

e.TM_Emp_Id = 101

它显示的排名为 1。对于每个用户，我都会得到相同的结果(即排名 1)。但我想显示原始排名。我该如何实现这一目标？提前致谢!

Answer 1

为此，您至少有 3 个简单的选择。

1. 将整个查询封装到子查询中，使其看起来像

   select * 
   from (current code) 
   where TM_Emp_ID = 101
   

2. 与上面相同，只是将其设为 CTE:

   WITH MY_QUERY AS 
   (current code) 
   SELECT * 
   FROM MY_QUERY 
   WHERE TM_EMP_ID = 101
   

3. 与上面两个相同，只是使用临时表
