How do I use the view I created to get different data outputs. I have created the view VJobCustomerLaborCost. This view gives each job for each customer with total of labor cost for each job. I need to get each customer with total labor cost for each customer. I have given the View and sample outputs.
GO
CREATE VIEW VJobCustomerLaborCost
AS
SELECT DISTINCT
TJ.intJobID
,TJ.strJobDescription
,TC.intCustomerID
,TC.strLastName + ', ' + TC.strFirstName AS strCustomerName
,SUM(TJE.intHoursWorked * TE.monHourlyRate) AS monTotalLaborCost
FROM
TJobs AS TJ
,TJobCustomers AS TJC
,TCustomers AS TC
,TJobEmployees AS TJE
,TEmployees AS TE
WHERE
TJ.intJobID = TJC.intJobID
AND TJC.intCustomerID = TC.intCustomerID
AND TJ.intCustomerID = TJC.intCustomerID
AND TJE.intJobID = TJ.intJobID
GROUP BY
TJ.intJobID
,TJ.strJobDescription
,TC.intCustomerID
,TC.strLastName
,TC.strFirstName
GO
This is the output from my view. This gives me all customers and each jobs total labor cost
intJobID strJobDescription intCustomerID strCustomerName monTotalLaborCost

What I need is to use the View created to get total labor cost for each customer. So output would be
intCustomerID strCustomerName monTotalLaborCost
------------------- ----------------- ---------------------
1 Belcher, Bob 37,430
3 Parker, Peter 5,510
4 Solo, Hans 2,850
2 Stark, Tony 0.00
How do I use the above view to get this output?
It looks like you need just to group and sum your data:
select
intCustomerID,
strCustomerName,
sum(monTotalLaborCost) as monTotalLaborCost
from VJobCustomerLaborCost
group by intCustomerID, strCustomerName

I have 2 Tables (History and Responsible). They need to be JOINED based on Service Date.

My code produces multiple rows, because 2022-01-14 Service date falls under multiple date ranges from Responsible Table:
SELECT h.Id,
h.ServiceDate,
h.Hours,
h.ClientId,
h.ClientName,
r.ResponsibleName
FROM History AS h
LEFT JOIN Responsible AS r
ON (h.ClientId = r.ClientId AND h.ServiceDate BETWEEN r.ResponsibleStartDate AND r.ResponsibleEndtDate)
The output of the query above is:
Id
ServiceDate
Hours
ClientId
ClientName
ResponsibleName

Technically, output is correct (because 2022-01-14 is between 2021-10-18 - 2999-12-31 as well between 2022-01-07 - 2999-12-31), but not what I need.
I would like to know if possible to achieve 2 outputs:
1) If Service Date falls in multiple date ranges from Responsible Table, Responsible Should be the person who's ResponsibleStartDate is closer to the ServiceDate:
Id
ServiceDate
Hours
ClientId
ClientName
ResponsibleName

2) Keep all rows, if Service Date falls in multiple date ranges from Responsible Table, but split Hours evenly between Responsible:
Id
ServiceDate

First one, we can use a window function to apply a row number, based on how close to ServiceDate the ResponsibleStartDate is, then we can just pick the first row per h.Id. If there is a tie we can break it by picking something that will give us deterministic order, e.g. ORDER BY {DATEDIFF expression}, ResponsibleName.
;WITH cte AS
(
SELECT h.Id,
h.ServiceDate,
h.Hours,
h.ClientId,
h.ClientName,
r.ResponsibleName,
RankOrderedByProximityToServiceDate = ROW_NUMBER() OVER
(PARTITION BY h.Id
ORDER BY ABS(DATEDIFF(DAY, ResponsibleStartDate, ServiceDate)))
FROM dbo.History AS h
LEFT JOIN dbo.Responsible AS r
ON (h.ClientId = r.ClientId
AND h.ServiceDate BETWEEN r.ResponsibleStartDate AND r.ResponsibleEndtDate)
)
SELECT Id, ServiceDate, Hours, ClientId, ClientName, ResponsibleName
FROM cte WHERE RankOrderedByProximityToServiceDate = 1;
Output:
Id
ServiceDate
Hours
ClientId
ClientName
ResponsibleName

Second one doesn't require a CTE, we can simply divide the Hours in h by the number of rows that exist for that h.Id, then limit it to 2 decimal places:
SELECT h.Id,
h.ServiceDate,
Hours = CONVERT(decimal(11,2),
h.Hours * 1.0
/ COUNT(h.Id) OVER (PARTITION BY h.Id)),
h.ClientId,
h.ClientName,
r.ResponsibleName
FROM dbo.History AS h
LEFT JOIN dbo.Responsible AS r
ON (h.ClientId = r.ClientId
AND h.ServiceDate BETWEEN r.ResponsibleStartDate AND r.ResponsibleEndtDate);
Output:
Id
ServiceDate
Hours
ClientId
ClientName
ResponsibleName

Both demonstrated in this db<>fiddle.
My attempt at part 1 - it doesn't work if there's more than one Responsible as of the same start date.
WITH
"all_services" AS (
SELECT
h.Id,
h.ServiceDate,
h.Hours,
h.ClientId,
h.ClientName,
r.ResponsibleName,
r.ResponsibleStartDate
FROM History AS h
LEFT JOIN Responsible AS r
ON h.ClientId = r.ClientId
AND h.ServiceDate BETWEEN r.ResponsibleStartDate AND r.ResponsibleEndtDate
),
"most_recent_key" AS (
SELECT
ServiceDate,
ClientId,
MAX(ResponsibleStartDate) AS "ResponsibleStartDate"
FROM all_services
GROUP BY ServiceDate, ClientId
)
SELECT Id, ServiceDate, Hours, ClientId, ClientName, ResponsibleName
FROM all_services
INNER JOIN most_recent_key
USING (ServiceDate, ClientId, ResponsibleStartDate)
Posting it anyway as a contrast to Aaron's better solution as a learning point for myself.
I am currently working with three tables where I am trying to figure out how to use a join to display once the title_id of any book with Dennis McCann as an editor. The tables have in common title_id and editor_id. Cant find a way to piece it all together. How to display once the title_id of any book with Dennis McCann as an editor?
SELECT * FROM title_editors;
EDITOR_ID TITLE_ EDITOR_ORDER

You can try join on the table Editors and Ttile_Editors using the Editor_ID that will give you the matching records and you can filter out Only for the ' Dennis McCann ' using either multiple conditions in join or the where clause as,
WITHOUT WHERE
SELECT DISTINCT te.title_id,ed.EDITOR_ID,ed.EDITOR_LNAME,ed.EDITOR_FNAME
FROM
title_editors te JOIN editors ed
ON te.EDITOR_ID = ed.EDITOR_ID
AND ed.EDITOR_LNAME = 'McCann'
AND ed.EDITOR_FNAME = 'Dennis'
ORDER BY te.title_id
USing WHERE
SELECT DISTINCT te.title_id,ed.EDITOR_ID,ed.EDITOR_LNAME,ed.EDITOR_FNAME
FROM
title_editors te JOIN editors ed
ON te.EDITOR_ID = ed.EDITOR_ID
WHERE
ed.EDITOR_LNAME = 'McCann'
AND ed.EDITOR_FNAME = 'Dennis'
ORDER BY te.title_id
It would be easier with the in operator:
SELECT DISTINCT title_id
FROM title_editors
WHERE editor_id IN (SELECT editor_id
FROM editors
WHERE editor_fname = 'Dennis' AND
editor_lname = 'McCann')
ORDER BY title_id ASC

Thank you.
select u.id, u.name, s.saldo, p.last_paid_date, p2.amount
from users u
join saldo s
on u.id = s.user_id
join (select user_id, max(paid_date) as last_paid_date
from payments
group by user_id) p
on u.id = p.user_id
join payments p2
on p.last_paid_date = p2.paid_date
and p.user_id = p2.user_id
This answer assumes:
(1) On table SALDO, there is one row per USER_ID
(2) On table PAYMENTS, there can be multiple rows per USER_ID
(I'm pretty confident about #2 being true, I don't know about #1, as you didn't say and your sample data doesn't indicate one way or the other)
I am trying to create a view that records the selected attributes for all Computer Science majors.
This is my query to create a view:
DROP VIEW CS_grade_report;
CREATE VIEW CS_grade_report AS
SELECT Student.student_id AS "ID",

AND Class.schedule_num = Enrolls.schedule_num;
SELECT *

I am assuming this is output from sqlplus. There is a "pagesize" option to define when breaks are added. If you only want to see one heading, set the size to a large enough value prior to running your SELECT statement as such:
set pagesize 500
(or whatever size you want)
There are many command options for sqlplus. This link is a good cheat-sheet.
I have database table that I am after some SQL for (Which is defeating me so far!)
Imagine there are 192 Athletic Clubs who all take part in 12 Track Meets per season.
So that is 2304 individual performances per season (for example in the 100Metres)
I would like to find the top 48 (unique) individual performances from the table, these 48 athletes are then going to take part in the end of season World Championships.
So imagine the 2 fastest times are both set by "John Smith", but he can only be entered once in the world champs. So i would then look for the next fastest time not set by "John Smith"... so on and so until I have 48 unique athletes..
hope that makes sense.
thanks in advance if anyone can help
PS
I did have a nice screen shot created that would explain it much better. but as a newish user i cannot post images.
I'll try a copy and paste version instead...
