如何找到拥有两个特定许可证的人，单独的行，只有一个具有有限许可证

Question

我正在尝试组合一个查询，这样我就可以在我们的数据库中找到既有 NY permit/license 也有有限 permit/license 的人，但是这些行是单独的行询问。我只想要那些没有纽约州驾照的，那里是有限制的。

这是我目前拥有的：

p.Last_Name
,p.First_Name
,p.Middle_Initial
,p.person_id
,i.Document
,i.Expiration_date
,i.Updated_Date
--,i.IssueDate
--,i.Historical
--,i.Comments
--,f.Current_status
,i.State 

from dbo.PersonDoc_ID_Numbers i

inner join "DB"."dbo"."People" p on p.person_id = i.person_id
inner  join person_facilities f on p.person_id = f.person_id

where
(Document like '%limited%' and i.State like '%NY%' and ((i.Expiration_date > getdate()) or (i.Expiration_date is null))) or 
(Document like '%NY%' and i.State like '%NY%' and ((i.Expiration_date > getdate()) or (i.Expiration_date is null)))
and f.current_status in ('Active') 
and i.Historical != 1

order by p.Last_Name

所以这 return 对某些人来说是这样的，但我不想要拥有纽约执照的人以及有限的人；我只想要没有纽约牌照的限量版：

Last_Name   First_Name  Middle_Initial  person_id   Document           Expiration_date  Updated_Date
    GG       FF         L.          123             Limited Permit     2019-09-23       2018-10-04 456  
    GG       FF         L.          123             NY State License       NULL           2018-11-13 
    Smith        Tony   L.          456             Limited Permit     2019-09-23       2018-10-04 456  
    Snoopy       Dog    L.          789             NY State License       NULL           2018-11-13

所以对于 FF GG，我对她的名字被 returned 不感兴趣，因为她有任何执照，而且是有限的。我只想要有限的。但我希望 return Tony Smith 就是这样。

5         Sarah          Gd           
6         Bethany        Yoda

我在 id table 中的那些旁边放了一个 *，它们应该在最后一组。请注意，事实证明 FF GG 没有执照号码，因此她需要在最后一组。

假设您当前的查询一切正常，您可以使用 COUNT(*) OVER(PARTITION BY p.person_id) AS noOfRows 来确定查询将生成多少行，然后 select 只有单行的条目以及沿着这些行的查询:

WITH myCte AS (
    SELECT
    p.Last_Name
    ,p.First_Name
    ,p.Middle_Initial
    ,p.person_id
    ,i.Document
    ,i.Expiration_date
    ,i.Updated_Date
    ,i.IssueDate
    ,i.Historical
    ,i.Comments
    ,f.Current_status
    ,i.State as DocumentState
    ,COUNT(*) OVER(PARTITION BY p.person_id) AS noOfRows
  from dbo.PersonDoc_ID_Numbers i
  inner join "DB"."dbo"."People" p on p.person_id = i.person_id
  left join person_facilities f on p.person_id = f.person_id
  where
  (Document like '%limited%' and i.State like '%NY%' and ((i.Expiration_date > getdate()) or (i.Expiration_date is null))) or 
  (Document like '%NY%' and i.State like '%NY%' and ((i.Expiration_date > getdate()) or (i.Expiration_date is null)))
  and f.current_status in ('Active') 
  and i.Historical != 1
)

SELECT Last_Name
  ,First_Name
  ,Middle_Initial
  ,person_id
  ,Document
  ,Expiration_date
  ,Updated_Date
  ,IssueDate
  ,Historical
  ,Comments
  ,Current_status
  ,DocumentState 
FROM myCte
WHERE noOfRows = 1
AND Document like '%limited%'

这是工作中的一个简化示例：SQLFiddle

编辑：

鉴于您提供的示例数据，这是我建议的解决方案：

WITH myCte AS (
  SELECT
    p.Last,
    p.First,
    p.person_id,
    i.Document,
    i.Expiration_date,
    i.Updated_Date,
    i.Historical,
    f.Current_status,
    i.State as DocumentState,
    COUNT(*) OVER(PARTITION BY p.person_id) AS noOfRows
  FROM dbo.PersonDoc_ID_Numbers i
  JOIN dbo.Person p ON p.person_id = i.person_id
  JOIN person_facilities f ON p.person_id = f.person_id
  WHERE
    (Document like '%limited%' AND i.State like '%NY%' AND ((i.Expiration_date > getdate()) OR (i.Expiration_date is null))) or 
    (Document like '%NY%' AND i.State like '%NY%' AND ((i.Expiration_date > getdate()) OR (i.Expiration_date is null)))
    AND f.current_status in ('Active') 
    AND i.Historical != 1
)

SELECT Last
  ,First
  ,person_id
  ,Document
  ,Expiration_date
  ,Updated_Date
  ,Historical
  ,Current_status
  ,DocumentState 
FROM myCte
WHERE noOfRows = 1
AND Document like '%limited%'

这是一个使用所提供数据的新示例：SQLFiddle

您可以试试下面的查询。

WITH cte AS (
    SELECT p.Last_Name
        , p.First_Name
        , p.Middle_Initial
        , p.person_id
        , i.Document
        , i.Expiration_date
        , i.Updated_Date
    FROM dbo.PersonDoc_ID_Numbers i
    JOIN "DB"."dbo"."People" p ON p.person_id = i.person_id
    JOIN person_facilities f ON p.person_id = f.person_id
    WHERE /*Document LIKE '%limited%' 
        AND i.State LIKE '%NY%' 
        AND*/ (i.Expiration_date > GETDATE() OR i.Expiration_date IS NULL)
        AND f.current_status IN ('Active') 
        AND i.Historical != 1
)
SELECT *
FROM cte c
WHERE Document LIKE '%limited%' AND i.State LIKE '%NY%' 
    AND NOT EXISTS (
        SELECT 1
        FROM cte
        WHERE person_id = p.person_id AND Document NOT LIKE '%limited%' AND i.State LIKE '%NY%'
    )
ORDER BY Last_Name
