I have 2 tables; the first one ORG contains the following columns:
ORG_REF, ARB_REF, NAME, LEVEL, START_DATE
and the second one WORK contains these columns:
ARB_REF, WORK_STREET - WORK_NUM, WORK_ZIP
I want to do the following: write a select query that search in work and see if the WORK_STREET, WORK_ZIP are duplicate together, then you should look at WORK_NUM. If it is the same then output value ' ok ', but if WORK_NUM is not the same, output 'not ok'
I wrote this SQL query:
select
A.ARB_REF, A.WORK_STREET, A.WORK_NUM, A.WORK_ZIP
case when B.B = 1 then 'OK' else 'not ok' end
from
work A
join
(select
WORK_STREET, WORK_ZIP count(distinct , A.WORK_NUM) B
from
WORK
group by
WORK_STREET, WORK_ZIP) B on B.WORK_STREET = A.WORK_STREET
and B.WORK_ZIP = A.WORK_ZIP
Now I want to join the table ORG with this result I want to check if every address belong to org if it belong I should create a new column result and set it to yes in it (RESULT) AND show the "name" column otherwise set no in 'RESULT'.
Can anyone help me please?
While you can accomplish your result by adding a left outer join to the query you've already started, it might be easiest to just use count() over....
with org_data as (
-- do the inner join before the left join later
select * from org1 o1 inner join org2 o2 on o2.orgid = o1.orgid
)
select
*,
count(*) over (partition by WORK_STREET, WORKZIP) as cnt,
case when o.ARB_REF is not null then 'Yes' else 'No' end as result
from
WORK w left outer join org_data o on o.ARB_REF = w.ARB_REF

I have a table like
For each keyword, there are 2 devices - mobile and desktop. If entry for only one device is found, then it should automatically create the entry for other device keeping the data in rest of the columns same. I am currently doing a full outer join which is working fine for the case where one device category is missing but generating duplicates where both devices are present. For example,
my current query is giving the result as
select a.keyword, b.device, a.rating
from kw a full outer join kw b
on a.keyword=b.keyword and a.rating=b.rating
How do I get the result as
The first step will be to identify records that don't have a paired record. There's a couple of ways to do this, but the easiest is probably just a quick GROUP BY/HAVING:
SELECT keyword
FROM kw
GROUP BY keyword
HAVING COUNT(*) = 1
You can those join those results back into the original table to generate the new records that are needed:
SELECT sk.keyword,
CASE WHEN kw.device = 'mobile' THEN 'desktop' ELSE 'mobile' END as device,
kw.rating
FROM
(
SELECT keyword
FROM kw
GROUP BY keyword
HAVING COUNT(*) = 1
)sk
INNER JOIN kw ON kw.keyword = sk.keyword
Then you can UNION back in the original table to bring your new records and existing records into a single result set:
SELECT sk.keyword,
CASE WHEN kw.device = 'mobile' THEN 'desktop' ELSE 'mobile' END as device,
kw.rating
FROM
(
SELECT keyword
FROM kw
GROUP BY keyword
HAVING COUNT(*) = 1
)sk
INNER JOIN kw ON kw.keyword = sk.keyword
UNION ALL
SELECT * FROM kw;
As another option that will scale if you add in more 'devices' is to cross join all the potential device/keyword combinations and then left join to your original table:
SELECT
fe.keyword,
fe.device,
CASE WHEN kw.rating IS NULL THEN max(rating) OVER (PARTITION BY fe.keyword) ELSE kw.rating END AS rating
FROM
(
SELECT DISTINCT kw.keyword, kw2.device
FROM kw, kw kw2
) fe
LEFT OUTER JOIN kw ON kw.keyword = fe.keyword
AND kw.device = fe.device;
I want to change this query:
select
t.AccountA
,t.AccountB
,t.totalNumber
,a.Category
from TableA t
left join Accounts a
on t.ActNum = a.ActNum
left join
(select distinct
s.col1
from (
select ....
from Table
group by...
) st
left join (select S....
group by..
) g on...
left join (select... on ...
) t on ...
where...
)
so that c.AccountB displays "X" if it was a "Y". So I want to do something like
CASE WHEN c.AccountB = 'Y' THEN 'X' ELSE 'c.AccountB END
Except I'm having a problem where some data (a.Category) is coming from the table a, and table a doesn't have a record in it equal to "Y", so the join doesn't get the category data from a. That field is therefore blank. I'm trying to avoid adding it to that table and would rather change the query. How can I do this? What I think would work is:
select
t.AccountA
,t.AccountB
,t.totalNumber
,a.Category
from TableA t
left join ****** (Select CASE WHEN t.AccountB = 'Y' THEN 'X' ELSE 't.AccountB END Accounts a)
on t.ActNum = a.ActNum
left join
(select distinct
col1
from (
select ....
from Table
group by...
) sta
left join (select S....
group by..
) g on...
left join (select... on ...
) t on ...
where...
)
Where I put the CASE expression in the 7th line here by the asterisks ***
Will this return exactly the same records? This is a really long running query and difficult to test so I'm trying to run it as few times as possible, would like some input to help me so this doesn't turn into a 6 hour project.
EDIT: I had a typo, the first columns selected were supposed to reference the first table - I changed it (table "t")
First, this might be as simple as getting rid of the single quote before c.AccountB CASE WHEN c.AccountB = 'Y' THEN 'X' ELSE c.AccountB END Otherwise I'm not quite sure I understand what you want but I'll try:
If you just want to select then:
select
c.AccountA
,CASE WHEN c.AccountB = 'Y' THEN 'X' ELSE c.AccountB END AccountB
,totalNumber
,a.Category
from TableA t
left join Accounts a
on t.ActNum = a.ActNum
left join
...
If instead you want to use this as part of a join you'll have to use it in your join. Since you don't show how "c" is joined, nor how "c" and "a" are related I will try to give an example:
select
c.AccountA
,CASE WHEN c.AccountB = 'Y' THEN 'X' ELSE c.AccountB END AccountB
,totalNumber
,a.Category
from CheckRegister c
left join Accounts a
on a.ActNum = c.AccountA
left join Accounts b
on b.ActNum = CASE WHEN c.AccountB = 'Y' THEN 'X' ELSE c.AccountB END
Having a slow day....could use some assistance writing a simple ANSI SQL query.
I have a list of individuals within families (first and last names), and a second table which lists a subset of those individuals. I would like to create a third table which flags every individual within a family if ANY of the individuals are not listed in the second table. The goal is essentially to flag "incomplete" families.
Below is an example of the two input tables, and the desired third table.
As I said...very simple...having a slow day. Thanks!
I think you want a left join and case expression:
select t1.*,
(case when t2.first_name is null then 'INCOMPLETE' else 'OK' end) as flag
from table1 t1 left join
table2 t2
on t1.first_name = t2.first_name and t1.last_name = t2.last_name;
Of course, this marks "Diane Thomson" as "OK", but I think that is an error in the question.
EDIT:
Oh, I see. The last name defines the family (that seems like a pretty big assumption). But you can do this with window functions:
select t1.*,
(case when count(t2.first_name) over (partition by t1.last_name) =
count(*) over (partition by t1.last_name)
then 'OK'
else 'INCOMPLETE'
end) as flag
from table1 t1 left join
table2 t2
on t1.first_name = t2.first_name and t1.last_name = t2.last_name;
That's not simple, at least not in SAS :-)
Standard SQL, when Windowed Aggregates are supported:
select ft.*,
-- counts differ when st.first_name is null due to the outer join
case when count(*) over (partition by ft.last_name)
= count(st.first_name) over (partition by ft.last_name)
then 'OK'
else 'INCOMPLETE'
end
from first_table as ft
left join second_table as st
on ft.first_name = st.first_name
and ft.last_name = ft.last_name
Otherwise you need to a standard aggregate and join back:
select ft.*, st.flag
from first_table as ft
join
(
select ft.last_name,
case when count(*)
= count(st.first_name)
then 'OK'
else 'INCOMPLETE'
end as flag
from first_table as ft
left join second_table as st
on ft.first_name = st.first_name
and ft.last_name = st.last_name
group by ft.last_name
) as st
on ft.last_name = st.last_name
It is pretty easy to do in SAS if you want to take advantage of its non-ANSI SQL feature of automatically re-merging aggregate function results back onto detail records.
select
a.first
, a.last
, case when 1=max(missing(b.last)) then 'INCOMPLETE'
else 'OK'
end as flag
from table1 a left join table2 b
on a.last=b.last and a.first=b.first
group by 2
order by 2,1

I have two tables, one contains a list of projects, another contains requests for this project. I would like to get the project number and the requests record. The status can be: Red, Yellow, Green, Open
How can I make sure that the 1 status record being shown follows the logic that when there is a Red one, show the red one, when there is no red one but there is a yellow one show this yellow one so on...
;WITH
numberTest as(
SELECT dbo.ServiceRequest.ID as numId,
ROW_NUMBER() OVER (PARTITION BY dbo.ServiceRequest.Project_ID order by Project_ID) AS RN1
FROM dbo.ServiceRequest
),
CTEVrequest AS
(
SELECT dbo.ServiceRequest.ID, dbo.ServiceRequest.Project_ID
FROM dbo.ServiceRequest
LEFT JOIN numberTest ON numberTest.numId = dbo.ServiceRequest.ID
WHERE numberTest.RN1 = 1
AND
dbo.ServiceRequest.ID = CASE
WHEN EXISTS(
select srvReq.ID
from dbo.ServiceRequest as srvReq
where requestStatus.ServiceStatus = 'R' AND srvReq.Project_ID = dbo.ServiceRequest.Project_ID)
THEN (select srvReq.ID
from dbo.ServiceRequest as srvReq
where requestStatus.ServiceStatus = 'R' AND srvReq.Project_ID = dbo.ServiceRequest.Project_ID)
WHEN EXISTS(
select srvReq.ID
from dbo.ServiceRequest as srvReq
where requestStatus.ServiceStatus = 'Y' AND srvReq.Project_ID = dbo.ServiceRequest.Project_ID)

CTEVrequest.ServiceStatus
FROM dbo.Project
LEFT JOIN CTEVrequest ON CTEVrequest.Project_ID = dbo.Project.ID
LEFT JOIN dbo.Project ON dbo.ServiceRequest.Project_ID = dbo.Project.ID
The problem is I get the "Subquery returned more than 1 value" error and I have no clue how to make the result check if there exists a record with Red and if not select the one with Yellow and so on.
Probably I did not understand you right, but looks like your query is supposed to do this:
SELECT *
FROM dbo.Project p
OUTER APPLY
(
SELECT TOP 1 sr.*
FROM dbo.ServiceRequest sr
WHERE sr.Project_ID = p.Project_ID
/* AND sr.ServiceStatus in ('R', 'Y') */
ORDER BY
CASE
WHEN sr.ServiceStatus = 'R' THEN 1
WHEN sr.ServiceStatus = 'Y' THEN 2
ELSE 3
END
) sr
Why don't you create a table that functions as a key for the statuses? For example:
IF OBJECT_ID('tempdb..#LevelKey') IS NOT NULL
DROP TABLE #LevelKey;
CREATE TABLE #LevelKey
(LevelText [varchar](255),
LevelValue INT);
INSERT INTO #LevelKey VALUES
('Red',1),
('Orange',2),
('Yellow',3),
('Green',4);
Now, join the project level to this key. When you want to grab the highest rank, you could do something like:
SELECT TOP 1 *
FROM Table
INNER JOIN #LevelKey ON LevelText = Whatever
ORDER BY LevelValue ASC
But that only works for one. So I'm not even sure why I included that. To bring back a group, you're going to have to do something like this:
SELECT ProjectID, MAX(LevelValue) AS LevelValue
FROM Table
INNER JOIN #LevelKey ON LevelText = Whatever
GROUP BY ProjectID
I have a table called Member_Id which has a column in it called Member_ID_Type. The select statement below returns the value of another column, id_value from the same table. The join on the tables in the select statement is on the universal id column. There may be several entries in that table with this same universal id.
I want to adjust the select statement so that it will return the id_values for entries that have member_id_type equal to '7'. However if this is null then I want to return records that have member_id_type equal to '1'
So previously I had a condition on the join (commented out below) but that just returned records that had member_id_type equal to '7' and otherwise returned null.
I think I may have to use a case statement here but I'm not 100% sure how to use it in this scenario
SELECT TOP 1 cm.Contact_Relation_Gid,
mc.Universal_ID,
mi.ID_Value,
cm.First_Name,
cm.Last_Name,
cm.Middle_Name,
cm.Name_Suffix,
cm.Email_Address,
cm.Disability_Type_PKID,
cm.Race_Type_PKID,
cm.Citizenship_Type_PKID,
cm.Marital_Status_Type_PKID,
cm.Actual_SSN,
cm.Birth_Date,
cm.Gender,
mc.Person_Code,
mc.Relationship_Code,
mc.Member_Coverage_PKID,
sc.Subscriber_Coverage_PKID,
FROM Contact_Member cm (NOLOCK)
INNER JOIN Member_Coverage mc (NOLOCK)
ON cm.contact_relation_gid = mc.contact_relation_gid
AND mc.Record_Status = 'A'
INNER JOIN Subscriber_Coverage sc (NOLOCK)
ON mc.Subscriber_Coverage_PKID = sc.Subscriber_Coverage_PKID
AND mc.Record_Status = 'A'
LEFT outer JOIN Member_ID mi ON mi.Universal_ID = cm.Contact_Gid
--AND mi.Member_ID_Type_PKID='7'
WHERE cm.Contact_Relation_Gid = #Contact_Relation_Gid
AND cm.Record_Status = 'A'
Join them both, and use one if the other is not present:
select bt.name
, coalesce(eav1.value, eav2.value) as Value1OrValue2
from BaseTable bt
left join EavTable eav1
on eav1.id = bt.id
and eav1.type = 1
left join EavTable eav2
on eav2.id = bt.id
and eav2.type = 2
This query assumes that there is never more than one record with the same ID and Type.
