具有计数和日期的SQL联合

再次询问，但希望更清楚。我有以下情况，这是完美的工作，你可以看到原来的问题，这是答案

DECLARE @imvw_woap_code_with_cust TABLE (
        pkey INT,
        Code_id VARCHAR(200),
        code_type_id VARCHAR(200),
        asset_standard_id VARCHAR(200),
        date_completed DATETIME
    )
INSERT INTO @imvw_woap_code_with_cust(pkey,Code_id,code_type_id,asset_standard_id,date_completed)
    SELECT 101480,'Alarmining','A-Problem','1 East','2017-08-10 02:00:30.013'
    UNION SELECT 103350,'Fluid/Gas Leak (Out)','A-Problem','2 west','2017-08-10 02:00:30.013'
    UNION SELECT 104033,'plug/Pwr Cord Damg','A-Problem','2 west','2017-08-10 02:00:30.013'
    UNION SELECT 107296,'Alarmining','A-Problem','2 west','2017-09-11 02:00:30.013'
    UNION SELECT 106404,'Incoming Inspect','A-Problem','2 west','2017-08-10 02:00:30.013'
    UNION SELECT 106407,'Incoming Inspect','A-Problem','2 west','2017-09-11 02:00:30.013'
    UNION SELECT 106408,'Incoming Inspect','A-Problem','2 west','2017-09-12 02:00:30.013'

DECLARE @IMTBL_CODE TABLE (
    pkey INT,
    Code_id VARCHAR(200),
    code_type_id VARCHAR(200)
)

INSERT INTO @IMTBL_CODE(pkey,Code_id,code_type_id)
    SELECT 100064,'1-NO PROBLEM CODE ENTERED','A-Problem'
    UNION SELECT 100068,'Alarmining','A-Problem'
    UNION SELECT 100069,'Battery Failure','A-Problem'
    UNION SELECT 100070,'Incoming Inspect','A-Problem'
    UNION SELECT 100071,'Fluid/Gas Leak (Out)','A-Problem'
    UNION SELECT 100072,'Case Damaged','A-Problem'
    UNION SELECT 100073,'plug/Pwr Cord Damg','A-Problem'


CREATE VIEW cause_codes as
SELECT
        possibilities.code_id AS code_id,
        possibilities.asset_standard_id,
        Count(U.pkey) AS [COUNT]
FROM (
    SELECT
        a.asset_standard_id,b.code_id
    FROM (SELECT DISTINCT asset_standard_id FROM @imvw_woap_code_with_cust) AS a
    CROSS JOIN (
        SELECT DISTINCT code_id FROM @imtbl_code
        UNION
        SELECT DISTINCT CODE_ID AS [ID] FROM @imvw_woap_code_with_cust 
    ) AS b
) AS possibilities
LEFT OUTER JOIN @imvw_woap_code_with_cust AS U ON U.code_id = possibilities.code_id
    AND possibilities.asset_standard_id=u.asset_standard_id
    and u.code_type_id='A-Problem'
GROUP BY possibilities.code_id, possibilities.asset_standard_id
order by [count]

一旦我将其创建到视图（cause_code）中，它将返回一个整洁的表，其中包含代码出现的次数计数（也包括0计数）

然后客户回来了，希望添加日期 所以如果我在视图中添加日期

ALTER VIEW cause_codes as
    SELECT
            possibilities.code_id AS code_id,
            possibilities.asset_standard_id,
            Count(U.pkey) AS [COUNT],
            U.date_created
    FROM (
        SELECT
            a.asset_standard_id,b.code_id
        FROM (SELECT DISTINCT asset_standard_id FROM @imvw_woap_code_with_cust) AS a
        CROSS JOIN (
            SELECT DISTINCT code_id FROM @imtbl_code
            UNION
            SELECT DISTINCT CODE_ID AS [ID] FROM @imvw_woap_code_with_cust 
        ) AS b
    ) AS possibilities
    LEFT OUTER JOIN @imvw_woap_code_with_cust AS U ON U.code_id = possibilities.code_id
        AND possibilities.asset_standard_id=u.asset_standard_id
        and u.code_type_id='A-Problem'
    GROUP BY possibilities.code_id, possibilities.asset_standard_id,date_created
    order by [count]

然后进行搜索

 select * from cause_codes where asset_standard_id = '2 west' and date_completed > '2017-09-10 02:00:30.013' and date_completed < '2017-09-12 02:00:30.013'

有没有一种方法可以做到这一点（添加一个搜索日期），但仍然保持单行的正确计数

我希望这是清楚的。。。这是一个相当大的问题。

感谢您花时间阅读我的书：）

每当您按日期分组，并且该日期有多个唯一值时，您将获得每个日期的多行，每个唯一日期的分组总和。请注意，您现在要求提供每个代码、资产id和日期的汇总汇总数据

您必须获取新日期值的最小值或最大值（另一个摘要），而不是按日期分组，或者如果您想要并且您确定不会获得一个大的日期列表，您可以将它们列在一个逗号分隔的列表中，以供行的可能日期使用，如果您想这样做的话。下面是一个使用For Xml技巧将日期列表与其他表区分开来的示例。在网上还有其他的例子

select
    RepName, DateList
from
    (
        select
            FirstName + ' ' + LastName as RepName, PersonID
        from
            Person
        where
            PersonID in (23164,30637,29985,25643)
    ) as p
    cross apply (
        select stuff ( (
            select
                ', ' + convert(varchar(16), CallDate, 101)
            from    
            (
                select
                    distinct TheDate
                from
                    dbo.Info as c
                    inner join Person as p2 on p2.PersonID = c.PersonID
                where
                    p2.PersonID = p.PersonID
            ) as dat
            order by CallDate
            for xml path('')
        ), 1, 2, '') as DateList
    ) as dateList

我是按自己的方式先到的，我没有衡量业绩

;WITH Activity As
(
    SELECT Count = COUNT(*),Customer.Code_id,Customer.asset_standard_id
    FROM @imvw_woap_code_with_cust Customer
    GROUP BY Customer.Code_id,asset_standard_id
),
Groups AS
(
    SELECT Code_id,asset_standard_id 
    FROM @IMTBL_CODE Codes
    CROSS APPLY (SELECT DISTINCT asset_standard_id FROM @imvw_woap_code_with_cust) X
), 
GroupedActivity AS
(
    SELECT Groups.Code_id,Groups.asset_standard_id,Count = CASE WHEN Activity.Count IS NULL THEN 0 ELSE Activity.Count END
    FROM Groups
    LEFT OUTER JOIN Activity ON Activity.Code_id = Groups.Code_id AND Activity.asset_standard_id = Groups.asset_standard_id
)
SELECT
    C.pkey,
    G.Code_id,
    G.asset_standard_id,
    G.Count,
    C.date_completed
FROM
    @imvw_woap_code_with_cust C
    INNER JOIN GroupedActivity G ON G.Code_id = C.Code_id AND G.asset_standard_id = C.asset_standard_id
WHERE
    G.asset_standard_id = '2 west' and date_completed > '2017-09-10 02:00:30.013' and date_completed < '2017-09-12 02:00:30.013'

从结果中选择最小或最大日期可以吗？如果是这样的话，您可以将创建的日期添加到分组中以规范化计数，或者您希望在任意窗口内返回组内所有日期的总数吗？它需要在任意窗口内返回。。糟糕透了！LOLI认为您的数据应该是-->Incoming Inspect（3）| Alarmining（1），用于您上面提供的筛选器。您从上面的问题中从哪里获得PersonID？我没有，我使用了一个来自我访问过的数据的示例，然后尝试对原始架构进行注释。我想我对自己的语法没有信心，不先测试就从内存中执行。
