Как получить количество номеров счетов, возвращаемых моим запросом, используя count (случай, когда)?

Question

SELECT DISTINCT
    s.branch AS [Branch]
    , s.CREATEDBYUSER AS [Teller Number]
    , acct.accountnumber AS [Account Number]
    , COUNT( DISTINCT CASE WHEN s.CLOSEDATE is null 
        AND s.CHARGEOFFDATE is NULL
        then s.PARENTACCOUNT
        else 0
        END
    ) AS [Shares]
    , CASE WHEN s.CLOSEDATE is null 
        AND s.CHARGEOFFDATE is NULL 
        THEN s.balance 
        else 0
    END AS [SharesBalance]
    , CASE WHEN s.CLOSEDATE is null 
        AND s.CHARGEOFFDATE is NULL
        THEN s.TYPE
        ELSE 0
    END AS [Share Type]
    , CASE WHEN s.CLOSEDATE is null 
        AND s.CHARGEOFFDATE is NULL
        then s.DESCRIPTION 
        ELSE NULL
    END AS [Share Description]
from ARCUSYM000.dbo.ACCOUNT acct
    left join ARCUSYM000.dbo.savings s
        on acct.ACCOUNTNUMBER = s.PARENTACCOUNT and s.ProcessDate = acct.ProcessDate
where acct.CLOSEDATE is null  
    AND s.CLOSEDATE is null 
    AND s.chargeoffdate is null 
    AND ((s.OPENDATE >= @StartDate AND s.OPENDATE <= @EndDate)
    OR (acct.OPENDATE >= @StartDate AND acct.OPENDATE <= @EndDate))
    AND acct.memberstatus = 0 
    AND s.branch is not null 
    AND s.branch IN (@BranchNum)
    AND s.ProcessDate = CONVERT(VARCHAR(8), dateadd(day,-1, getdate()), 112)
    AND acct.ProcessDate = CONVERT(VARCHAR(8), dateadd(day,-1, getdate()), 112)
GROUP BY s.BRANCH
    , s.CREATEDBYUSER
    , acct.ACCOUNTNUMBER
    , s.CLOSEDATE
    , s.CHARGEOFFDATE
    , s.BALANCE
    , s.TYPE
    , s.DESCRIPTION
    , s.SHARECODE
    , s.OVERDRAFTTOLERANCE
    , s.OPENDATE
ORDER BY s.CREATEDBYUSER, acct.ACCOUNTNUMBER

Сейчас я получаю количество номеров счетов для каждого типа акций. Если для номера учетной записи имеется более одной записи, я хотел бы подсчитать, сколько существует записей.

Я пробовал использовать раздел, но это тоже не помогло.

SELECT q.Branch
, q.[Teller Number]
, q.[Account Number]
, COUNT(q.Shares) OVER (PARTITION BY q.[Account Number]) AS [Shares]
, q.SharesBalance
, q.[Share Type]
, q.[Share Description]

) q
GROUP BY q.Branch
, q.[Teller Number]
, q.[Account Number]
, q.SharesBalance
, q.Shares

, q.[Share Description]

Я сделал подзапрос из своего запроса и получил желаемый результат.

Answer 2

Если вы можете сложить count(distinct) s, чтобы получить то, что вы хотите (как в вашем примере, вы можете использовать оконные функции:

SUM(COUNT(DISTINCT CASE WHEN s.CLOSEDATE is null AND s.CHARGEOFFDATE is NULL
                        THEN s.PARENTACCOUNT
                   END
          )
    ) OVER (PARTITION BY acct.accountnumber) AS [Shares]

Это немного сложнее, если вам нужен COUNT(DISTINCT) по всем строкам для учетной записи.

Примечание: ELSE 0 с COUNT(DISTINCT) кажется подозрительным. Я удалил предложение ELSE. По умолчанию NULL и не будет учитываться.
