I have a chart that I want to display resources name and number of requests they are working on for each status type. e.g. John Smith has 5 - in progress, 4 - not started, 5 - analysis, 0 - on Hold.
My query pulls all records for John Smith but only shows records that exist. How do I force the result table to show the zero for John Smith that is on hold?
The results I want to show are 10 staff, with each staff showing all my status that are available (Not started, In Progress, On Hold, Analysis, Deferred etc.) and zero if no projects are in a particular phase for that resource.
Below image shows resource on far left but if some don't have a particular status it doesn't show. I want all status to show even if it is zero.

Use left outer join and group the result.You will get Null if no record exists against 'John Smith'.
Try case when to convert null to zero.
As a concept, produce a list of all staff and available statuses, then left join the data to this. This will provide a row for each, even if it does not exist for that member of staff.
SQL server / oracle
with staff as
(
select staffname, status
from (select distinct staffname from table1)
cross join (select distinct status from table1)
)
select staff.*, table1.OtherColumns
from staff
left join table1
on staff.staffname = table2.staffname
and staff.status = table2.status
MySQL:
select staff.*, table1.OtherColumns
from
(
select staffname, status
from (select distinct staffname from table1)
cross join (select distinct status from table1)
) staff
left join table1
on staff.staffname = table2.staffname
and staff.status = table2.status

I have a table with student info [STU] and a table with parent info [PAR]. I want to return an email address for each student, but just one. So I run this query:
SELECT [STU].[ID], [PAR].[EM]
FROM (SELECT [STU].* FROM DB1.STU)
STU LEFT JOIN (SELECT [PAR].* FROM DB1.PAR) PAR ON [STU].[ID] = [PAR].[ID]
This gives me the below table:
Student ID ParentEmail
1 jim#email.com
1 sarah#email.com
2 paul#email.com
2 tim#email.com
3 bill#email.com
3 frank#email.com
3 joyce#email.com
4 greg#email.com
5 tony#email.com
5 sam#email.com
Each student has multiple parent emails, but I only want one. In other words, I want the output to look like this:
Student ID ParentEmail
1 jim#email.com
2 paul#email.com
3 frank#email.com
4 greg#email.com
5 sam#email.com
I've tried so many things. I've tried using GROUP BY and MIN/MAX and I've tried complex CASE statements, and I've tried COALESCE but I just can't seem to figure it out.
I think OUTER APPLY is the simplest method:
SELECT [STU].[ID], [PAR].[EM]
FROM DB1.STU OUTER APPLY
(SELECT TOP (1) [PAR].*
FROM DB1.PAR
WHERE [STU].[ID] = [PAR].[ID]
) PAR;
Normally, there would be an ORDER BY in the subquery, to give you control over which email you want -- the longest, shortest, oldest, or whatever. Without an ORDER BY it returns just one email, which is what you are asking for.
If you just want one column from the parent table, a simple approach is a correlated subquery:
select
s.id student_id,
(select max(p.em) from db1.par p where p.id = s.id) parent_email
from db1.stu s
This gives you the greatest parent email per student.
Im trying to remove all instances of a record if the value in the flag field is 4. (this means they have unsubscribed from the email list)
Sample data:
Customer# Email Name CustomerType Flag
001 email#email.com Bob Vet 1
001 email#email.com Bob Med 2
001 email#email.com Bob Pod 4
So since there is an instance that this record has a Flag of 4, all 3 should be removed from this query. They don't need to actually be deleted from the database, I just don't need the data to come up in my query. How do I approach this?
Assuming that the customer number is what links the records together, you can use a not exists clause:
select *
from tbl t1
where not exists (select *
from tbl t2
where t2.[Customer#] = t1.[Customer#]
and t2.Flag = 4)
Three approaches.
use Not exists
use a where not in
use a join
Below is the join: Sstan provided the not exists and Gordon more or less provided the where in but change to not in and a select and you'd have it as well.
Without table size volume of translations and index information I can't say which would offer the best performance though the not exists is the strong favorite.
SELECT A.*
FROM TableName A
LEFT JOIN TableName B
on A.Customer# = B.Customer#
and B.Flag = 4
WHERE B.Customer# is null
This does a self join but only to a set of records that are flagged as 4. it then excludes those records which have a match; returning only customer#'s which don't have a 4.
Here is one method:
delete from sample
where customer# in (select customer# from sample as s2 where flag = 4);
EDIT:
You can readily adapt this to a select:
select s.*
from sample s
where customer# not in (select customer# from sample as s2 where flag = 4);
I have 3 tables I need to put together.
The first table is my main transaction table where I need to get distinct transaction id numbers and company id. It has all the important keys. The transaction ids are not unique.
The second table has item info which is linked to transaction id numbers which are not unique and I need to pull items.
The third table has company info which has company id.
Now I've sold some of these with the first one through a group by id. The second through a subquery which creates unique ids and joins onto the first one.
The issue I'm having is the third one by company. I cannot seem to create a query that works in the above combinations. Any ideas?
As suggested here is my code. It works but that's because for the company I used count which doesn't give the correct number. How else can I get the company number to come out correct?
SELECT
dep.ItemIDAPK,
dep.TotalOne,
dep.company,
company.vendname,
appd.ItemIDAPK,
appd.ItemName
FROM (
SELECT
csi.ItemIDAPK,
sum(f.TotalOne) as TotalOne,
count(f.DimCurrentcompanyID) company
FROM dbo.ReportOne F with (nolock)
INNER JOIN dbo.DSaleItem csi with (nolock)
on f.DSaleItemID = csi.DSaleItemID
INNER JOIN dbo.DimCurrentcompany cv
ON f.DimCurrentcompanyID = cv.DimCurrentcompanyID
INNER JOIN dbo.DimDate dat
on f.DimDateID = dat.DimDateID
where (
dat.date >='2013-01-29 00:00:00.000'
and dat.date <= '2013-01-30 00:00:00.000'
)
GROUP BY csi.ItemIDAPK
) as dep
INNER JOIN (
SELECT
vend.DimCurrentcompanyID,
vend.Name vendname
FROM dbo.DimCurrentcompany vend
) As company
on dep.company = company.DimCurrentcompanyID
INNER JOIN (
SELECT
c2.ItemIDAPK,
ItemName
FROM (
SELECT DISTINCT ItemIDAPK
FROM dbo.dimitem AS C
) AS c1
JOIN dbo.dimitem AS c2 ON c1.ItemIDAPK = c2.ItemIDAPK
) as appd
ON dep.ItemIDAPK = appd.ItemIDAPK
For further information my output is the following example, I know the code executes and the companyid is incorrect as I just put it with a (count) in their to make the above code execute:
Current Results:
Item Number TLS CompanyID Company Name Item Number Item Name
111111 300 303 Johnson Corp 29323 Soap
Proposed Results:
Item Number TLS CompanyID Company Name Item Number Item Name
111111 300 29 Johnson Corp 29323 Soap
I'm trying to do an inner join in a nested select statement. Basically, There are first and last reason IDs that produce a certain number (EX: 200). In another table, there are definitions for the IDs. I'm trying to pull the Last ID, along with the corresponding comment for whatever is pulled (EX: 200 - Patient Cancelled), then the first ID and the comment for whatever ID it is.
This is what I have so far:
Select BUSN_ID
AREA_NAME
DATE
AREA_STATUS
(Select B.REASON_ID
A.LAST_REASON_ID
FROM BUSN_INFO A, BUSN_REASONS B
WHERE A.LAST_REASON _ID=B.REASON_ID,
(Select B.REASON_ID
A. FIRST_REASON_ID
FROM BUSN_INFO A, BUSN_REASONS B
WHERE A_FIRST_REASON_ID = B.REASON_ID)
FROM BUSN_INFO
I believe an inner join is best, but I'm stuck on how it would actually work.
Required result would look like (this is example dummy data):
First ID -- Busn Reason -- Last ID -- Busn Reason
1 Patient Sick 2 Patient Cancelled
2 Patient Cancelled 2 Patient Cancelled
3 Patient No Show 1 Patient Sick
Justin_Cave's SECOND example is the way I used to solve this problem.
If you want to use inline select statements, your inline select has to select a single column and should just join back to the table that is the basis of your query. In the query you posted, you're selecting the same numeric identifier multiple times. My guess is that you really want to query a string column from the lookup table-- I'll assume that the column is called reason_description
Select BUSN_ID,
AREA_NAME,
DATE,
AREA_STATUS,
a.last_reason_id,
(Select B.REASON_description
FROM BUSN_REASONS B
WHERE A.LAST_REASON_ID=B.REASON_ID),
a.first_reason_id,
(Select B.REASON_description
FROM BUSN_REASONS B
WHERE A.FIRST_REASON_ID = B.REASON_ID)
FROM BUSN_INFO A
More conventionally, though, you'd just join to the busn_reasons table twice
SELECT i.busn_id,
i.area_name,
i.date,
i.area_status,
i.last_reason_id,
last_reason.reason_description,
i.first_reason_id,
first_reason.reason_description
FROM busn_info i
JOIN busn_reason first_reason
ON( i.first_reason_id = first_reason.reason_id )
JOIN busn_reason last_reason
ON( i.last_reason_id = last_reason.reason_id )
I have a SQL table consists of id, name, email,.... I have another SQL table that has id, email, emailstatus but these 2 id are different they are not related. The only thing that is common between these 2 tables are emails.
I would like to join these 2 tables bring all the info from table1 and if the email address from table 1 and table 2 are same and emailstatus is 'Bounced'. But the query that I am writing gives me more record than I expected because there are multiple rows in tbl_webhook(second table) for each row in Applicant(first table) .I want to know if applicant has EVER had an email bounce.
Query without join shows 23000 record but after join shows 42000 record that is because of duplicate how I can keep same 23000 record only add info from second table?
This is my query:
SELECT
A.[Id]
,A.[Application]
,A.[Loan]
,A.[Firstname]
,A.[Lastname]
,A.[Email],
,H.[Email], H.[EmailStatus] as BouncedEmail
FROM Applicant A (NOLOCK)
left outer join [tbl_Webhook] [H] (NOLOCK)
on A.Email = H.Email
and H.[event]='bounced'
this is sample of desired data:
id email name emailFromTable2 emailstatus
1 test2#yahoo.com lili test2#yahoo.com bounced
2 tesere#yahoo.com mike Null Null
3 tedfd2#yahoo.com nik tedfd2#yahoo.com bounced
4 tdfdft2#yahoo.com sam Null Null
5 tedft2#yahoo.com james tedft2#yahoo.com bounced
6 tedft2#yahoo.com San Null
Use a nested select for this type of query. I would write this as:
select id, application, load, firstname, lastname, email,
(case when BouncedEmail is not null then email end) as EmailFromTable2,
BouncedEmail
from (SELECT A.[Id], A.[Application], A.[Loan], A.[Firstname], A.[Lastname], A.[Email],
(case when exists (select 1
from tbl_WebHook h
where A.Email = H.Email and H.[event] = 'bounced'
)
then 'bounced
end) as BouncedEmail
FROM Applicant A (NOLOCK)
) a
You can also do this with cross apply, but because you only really need one column, a correlated subquery also works.
;WITH DistinctEmails
AS
(
SELECT * , rn = ROW_NUMBER() OVER (PARTITION BY [Email] ORDER BY [Email])
FROM [tbl_Webhook]
)
SELECT
A.[Id]
,A.[Application]
,A.[Loan]
,A.[Firstname]
,A.[Lastname]
,A.[Email],
,H.[Email], H.[EmailStatus] as BouncedEmail
FROM Applicant A (NOLOCK) left outer join DistinctEmails [H] (NOLOCK)
on A.Email = H.Email
WHERE H.rn = 1
and H.[event]='bounced'
i believe query below should be enough to select distinct bounced email for you, cheer :)
SELECT
A.[Id]
,A.[Application]
,A.[Loan]
,A.[Firstname]
,A.[Lastname]
,A.[Email],
,H.[Email], H.[EmailStatus] as BouncedEmail
FROM Applicant A (NOLOCK)
Inner join [tbl_Webhook] [H] (NOLOCK)
on A.Email = H.Email
and H.[EmailStatus]='bounced'
basically i just change the joining to inner join and change the 2nd table condition from event to emailstatus, if u can provide your table structure and sample data i believe i can help you up :)
