如何使用over（）函数列出出现次数，但只显示结果中列出的出现3次或多次？

Question

如果我只想查看已出现3次以上的次数，如何列出每个帐号发生的次数？

我正在使用窗口OVER（）函数来获取列出帐号的次数。

SELECT a.ACCOUNTNUMBER AS [Account Number]
    , CONCAT(n.FIRST, ' ', n.MIDDLE, ' ', n.LAST) AS [Member Name]
    , l.id AS [Loan ID]
    , COUNT(a.ACCOUNTNUMBER)
        OVER(partition by a.ACCOUNTNUMBER) as [Number of 
Tracking Record] 
    , n.EMAIL AS [Email]
    , n.HOMEPHONE AS [Phone Number]
FROM dbo.account a
INNER JOIN dbo.LOAN l
ON a.ACCOUNTNUMBER = l.PARENTACCOUNT
INNER JOIN dbo.LOANTRACKING lt
ON l.PARENTACCOUNT = lt.PARENTACCOUNT
AND l.ID = lt.ID
INNER JOIN dbo.NAME n 
ON a.ACCOUNTNUMBER = n.PARENTACCOUNT
WHERE lt.type = 46
AND l.ProcessDate = CONVERT(VARCHAR(8), dateadd(day,-1, getdate()), 
112)
AND lt.ProcessDate = CONVERT(VARCHAR(8), dateadd(day,-1, getdate()), 
112)
AND a.CLOSEDATE IS NULL
AND lt.EXPIREDATE IS NULL
GROUP BY a.ACCOUNTNUMBER, n.FIRST, n.MIDDLE, n.LAST, l.id, n.email, 
n.HOMEPHONE
ORDER BY [Account Number]

现在，我的结果是给我所有帐户在“跟踪记录数”列中列出的次数。 我只想查看出现“ 3”次或以上的帐号。

SELECT *   -- edit to include only your relevant columnns
FROM
(
SELECT a.ACCOUNTNUMBER AS [Account Number]
    , CONCAT(n.FIRST, ' ', n.MIDDLE, ' ', n.LAST) AS [Member Name]
    , l.id AS [Loan ID]
    , COUNT(a.ACCOUNTNUMBER)
        OVER(partition by a.ACCOUNTNUMBER) as [Number of 
Tracking Record] 
    , n.EMAIL AS [Email]
    , n.HOMEPHONE AS [Phone Number]
FROM dbo.account a
INNER JOIN dbo.LOAN l
ON a.ACCOUNTNUMBER = l.PARENTACCOUNT
INNER JOIN dbo.LOANTRACKING lt
ON l.PARENTACCOUNT = lt.PARENTACCOUNT
AND l.ID = lt.ID
INNER JOIN dbo.NAME n 
ON a.ACCOUNTNUMBER = n.PARENTACCOUNT
WHERE lt.type = 46
AND l.ProcessDate = CONVERT(VARCHAR(8), dateadd(day,-1, getdate()), 
112)
AND lt.ProcessDate = CONVERT(VARCHAR(8), dateadd(day,-1, getdate()), 
112)
AND a.CLOSEDATE IS NULL
AND lt.EXPIREDATE IS NULL
GROUP BY a.ACCOUNTNUMBER, n.FIRST, n.MIDDLE, n.LAST, l.id, n.email, 
n.HOMEPHONE
) MyQuery
WHERE MyQuery.[Number of Tracking Record] >= 3
ORDER BY [Account Number]

我在您的查询周围添加了一个“外部”查询，将您的查询用作子查询，并为那些条件为> = 3的查询过滤了该查询。 我将ORDER BY从内部查询移至外部查询，因为它仅用于排序结果，而不用于计算本身。
