Sql 如何使用count（case-when）获取查询返回的帐号计数？ 选择DISTINCT s、 分行作为[分行] ，s.CREATEDBYUSER AS[出纳员编号] ，acct.accountnumber为[帐号] ，计数（s.CLOSEDATE为空时的不同大小写） s.CHARGEOFFDATE为空 然后是s.PARENTACCOUNT 其他0 结束 )作为[股份] ，s.CLOSEDATE为空时的情况 s.CHARGEOFFDATE为空 然后是美国的平衡 其他0 终止为[共享余额] ，s.CLOSEDATE为空时的情况 s.CHARGEOFFDATE为空 然后是s型 其他0 结束为[股份类型] ，s.CLOSEDATE为空时的情况 s.CHARGEOFFDATE为空 然后是美国的描述 否则无效 结束为[股份说明] 从ARCUSYM000.dbo.ACCOUNT账户 左连接ARCUSYM000.dbo.s 在acct.ACCOUNTNUMBER=s.PARENTACCOUNT和s.ProcessDate=acct.ProcessDate上 其中acct.CLOSEDATE为空 s.CLOSEDATE为空 s.chargeoffdate为空 和（（s.OPENDATE>=@StartDate和s.OPENDATE=@StartDate和acct.OPENDATE

如果您可以将

count（distinct）

s相加以获得所需内容（如示例中所示，您可以使用窗口函数：

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

如果您需要对帐户的所有行进行

COUNT（DISTINCT）

计数，那么这就有点复杂了

注意：

ELSE 0

带有

COUNT（DISTINCT）

似乎可疑。我删除了

ELSE

子句。默认值为

NULL

，将不被计数。

选择q.Branch
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]

，q.[出纳员编号]
，q.[账号]
，将（q.份额）除以（按q[账号]划分）作为[份额]
，q.SharesBalance
，q.[股份类型]
，q.[股份说明]
