[英]How find people with two specific licenses, separate rows, only one with limited permit
I'm trying to put together a query so I can find people in our db that have both a NY permit/license and also a limited permit/license, but the rows are separate rows in the query. 我正在尝试将查询放在一起,以便我可以在我们的数据库中找到同时具有NY许可证/许可证以及有限许可证/许可证的人员,但这些行在查询中是单独的行。 I only want the ones without NYS license, where they are limited. 我只想要那些没有NYS许可证的人,他们是有限的。
This is what I have so far: 这是我到目前为止:
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
So that's returning like this for someone, but I don't want the ones with NY license as well as limited; 所以对于某人来说这样的回归,但我不希望那些有NY许可证的人也有限; I just want ones with limited without NY license: 我只想要那些没有NY许可证的人:
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
So for FF GG, I wouldn't be interested in her name being returned because she has ny license, and the limited. 所以对于FF GG,我不会对她的名字被退回感兴趣,因为她有ny许可证,而且有限。 I only want ones with just limited. 我只想要有限的。 But I would expect it to return Tony Smith and that's it. 但我希望它能归还托尼史密斯,就是这样。

I put an * next to the ones in the id table where they are expected to be in the end set. 我在id表的旁边放了一个*,它们应该在最终集中。 Note that it turns out FF GG doesn't have a license number so she needs to be in the end set. 请注意,事实证明FF GG没有许可证编号,因此她需要在最终设置中。
Assuming your current query is all fine, you could use COUNT(*) OVER(PARTITION BY p.person_id) AS noOfRows
to determine how many rows the query will generate, then select
only the entries with a single row with a query along these lines: 假设您当前的查询都很好,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,然后仅select
具有单行的条目以及沿这些行的查询:
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%'
Here's a simplified example of this at work: SQLFiddle 这是一个简单的例子: SQLFiddle
EDIT: 编辑:
Given the sample data you have provided, here is my suggested solution: 根据您提供的示例数据,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%'
Here's a new example using the data provided: SQLFiddle 这是使用提供的数据的新示例: SQLFiddle
You can try the query below. 您可以尝试以下查询。
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
