SQL查询 - 是否可以在此查询中添加Grand Total？

Question

SQL Server 2016 Enterprise，使用SSMS ...

我这样查询：

WITH SUMS AS (
SELECT
    dbo.BillingActivity.BillingCodeId AS [Billing Code],
    dbo.Clients.ClientName AS [Client Name],
    dbo.BillingCodes.Name AS [Billing Code Name]
    , SUM(CASE WHEN Details LIKE '%"LW":"True"%' THEN 1 ELSE 0 END) AS [LW]
    , SUM(CASE WHEN Details LIKE '%"MHN":"True"%' THEN 1 ELSE 0 END) AS [MHN]
    , SUM(CASE WHEN Details LIKE '%"EPAP":true%' THEN 1 ELSE 0 END) AS [EPAP]
    , SUM(CASE WHEN Details LIKE '%"EPAP (old)":"True"%' THEN 1 ELSE 0 END) AS [EPAPOld]
FROM dbo.BillingActivity
INNER JOIN dbo.BillingCodes ON dbo.BillingActivity.BillingCodeId=dbo.BillingCodes.Id
INNER JOIN dbo.Clients ON dbo.BillingActivity.ClientId=dbo.Clients.ID
WHERE dbo.BillingActivity.RecordDateTime BETWEEN '2017-11-09' AND '2017-11-10'
GROUP BY dbo.BillingActivity.BillingCodeId, dbo.BillingCodes.Name, dbo.Clients.ClientName)
SELECT 
    [Billing Code],
    [Client Name],
    [Billing Code Name],
    [LW],
    [MHN],
    [EPAP],
    [EPAPOld],
    SUM(LW+MHN+EPAP+EPAPOld) OVER (PARTITION BY [Billing Code Name]) AS [Billing Code Total]
FROM SUMS
ORDER BY [Client Name] ASC, [Billing Code Name] ASC

这给了我以下结果:(表格在这里拒绝正确排列，因此图像：

我想知道是否可能（到目前为止互联网研究会说不）是我是否可以添加到此查询以创建第9列，该列将显示列帐单代码总计中的所有金额的总和。它显示在哪一行并不重要，如果在所有行中显示相同的数量也不重要，我只需要在某处看到该列的总和。

请注意，“结算代码总计”名称是别名。这提出了另一项挑战。

非常感谢。

你不需要over()的billing code total子句，但你需要你想要的其他列，如下所示：

WITH
      sums AS (
                  SELECT
                        dbo.BillingActivity.BillingCodeId                                     AS [billing code]
                      , dbo.Clients.ClientName                                                AS [client name]
                      , dbo.BillingCodes.Name                                                 AS [billing code name]
                      , SUM(CASE WHEN Details LIKE '%"LW":"True"%' THEN 1 ELSE 0 END)         AS [lw]
                      , SUM(CASE WHEN Details LIKE '%"MHN":"True"%' THEN 1 ELSE 0 END)        AS [mhn]
                      , SUM(CASE WHEN Details LIKE '%"EPAP":true%' THEN 1 ELSE 0 END)         AS [epap]
                      , SUM(CASE WHEN Details LIKE '%"EPAP (old)":"True"%' THEN 1 ELSE 0 END) AS [epapold]
                  FROM dbo.BillingActivity
                  INNER JOIN dbo.BillingCodes ON dbo.BillingActivity.BillingCodeId = dbo.BillingCodes.Id
                  INNER JOIN dbo.Clients ON dbo.BillingActivity.ClientId = dbo.Clients.ID
                  WHERE dbo.BillingActivity.RecordDateTime BETWEEN '2017-11-09' AND '2017-11-10'
                  GROUP BY
                        dbo.BillingActivity.BillingCodeId
                      , dbo.BillingCodes.Name
                      , dbo.Clients.ClientName
            )
SELECT
      [Billing Code]
    , [Client Name]
    , [Billing Code Name]
    , [LW]
    , [MHN]
    , [EPAP]
    , [EPAPOld]
    , LW + MHN + EPAP + EPAPOld AS [billing code total]
    , SUM(LW + MHN + EPAP + EPAPOld) OVER() as all_sum
FROM sums
ORDER BY
      [Client Name] ASC
    , [Billing Code Name] ASC
