I have following query:
SQL> SELECT DISTINCT INSTRUCTORADDRESSMODPER.instructor_id, Instructor.instructor_name, InstructorRank.salary, Student.specification_id
2 FROM INSTRUCTORADDRESSMODPER
3 JOIN Student ON INSTRUCTORADDRESSMODPER.student_id = Student.student_id
4 JOIN Instructor ON INSTRUCTORADDRESSMODPER.instructor_id = Instructor.instructor_id
5 JOIN InstructorRank ON Instructor.instructor_rank = InstructorRank.instructor_rank
6 ORDER BY specification_id;
which has yielded following result:
I was trying to get result which shows same column values for instructors with same salary and same specification as highlighted in the figure. Now these two conditions require completely different checks and I don't even know how to get started.
You need something like this ?
SELECT instructor_id, instructor_name, instructor_name, specification_id
FROM (
SELECT DISTINCT INSTRUCTORADDRESSMODPER.instructor_id, Instructor.instructor_name, InstructorRank.instructor_name, Student.specification_id
, COUNT(distinct INSTRUCTORADDRESSMODPER.instructor_id)over(partition by InstructorRank.salary, Student.specification_id) cnt
FROM INSTRUCTORADDRESSMODPER
JOIN Student ON INSTRUCTORADDRESSMODPER.student_id = Student.student_id
JOIN Instructor ON INSTRUCTORADDRESSMODPER.instructor_id = Instructor.instructor_id
JOIN InstructorRank ON Instructor.instructor_rank = InstructorRank.instructor_rank
ORDER BY specification_id
)
WHERE cnt > 1
;
You can use the window function count as follows:
Select * from
(SELECT DISTINCT INSTRUCTORADDRESSMODPER.instructor_id, Instructor.instructor_name, InstructorRank.salary, Student.specification_id,
Count(1) over (partition by InstructorRank.salary, Student.specification_id) as cnt
FROM INSTRUCTORADDRESSMODPER
JOIN Student ON INSTRUCTORADDRESSMODPER.student_id = Student.student_id
JOIN Instructor ON INSTRUCTORADDRESSMODPER.instructor_id = Instructor.instructor_id
JOIN InstructorRank ON Instructor.instructor_rank = InstructorRank.instructor_rank)
Where cnt > 1
ORDER BY specification_id;
SQL> SELECT DISTINCT INSTRUCTORADDRESSMODPER.instructor_id,
Instructor.instructor_name,InstructorRank.salary, Student.specification_id
FROM INSTRUCTORADDRESSMODPER
WHERE 1=1
AND INSTRUCTORADDRESSMODPER.student_id = Student.student_id
AND INSTRUCTORADDRESSMODPER.instructor_id = Instructor.instructor_id
AND Instructor.instructor_rank = InstructorRank.instructor_rank
AND ORDER BY specification_id
AND ...;
With the above use, desired conditions can be added.

I want to include tcon.Inductive_Injection_Hours, tcon.Capacitive_Injection_Hours without applying group by. How can I do that?
SELECT
bp.Serial_Number,
tcon.Serial_Number AS ConverterSerialNumber,
MAX(tcon.Time_Stamp) AS DateStamp,
tcon.Inductive_Injection_Hours,
tcon.Capacitive_Injection_Hours
FROM
dbo.Bypass AS bp
INNER JOIN
dbo.Converter AS c ON bp.Bypass_ID = c.Bypass_ID
INNER JOIN
dbo.Converter_Tel_Data AS tcon ON c.Converter_ID = tcon.Converter_ID
WHERE
(bp.Site_ID = 7)
GROUP BY
bp.Serial_Number, tcon.Serial_Number,
tcon.Inductive_Injection_Hours, tcon.Capacitive_Injection_Hours
ORDER BY
ConverterSerialNumber
I have figured it out.
select [data].Serial_Number,Time_Stamp,Inductive_Injection_Hours,Capacitive_Injection_Hours,b.Serial_Number from Converter_Tel_Data as [data]
inner join dbo.Converter AS c On [data].Converter_ID = c.Converter_ID
inner join dbo.Bypass as b on c.Bypass_ID = b.Bypass_ID
WHERE
(Time_Stamp = (SELECT MAX(Time_Stamp) FROM Converter_Tel_Data WHERE Converter_ID = [data].Converter_ID)) And ([data].Site_ID=7)
ORDER BY [data].Serial_Number
You can use row_number - either in a CTE/derived table or using a trick with TOP 1.
Select Top 1 With Ties
bp.Serial_Number
, tcon.Serial_Number AS ConverterSerialNumber
, tcon.Time_Stamp AS DateStamp
, tcon.Inductive_Injection_Hours
, tcon.Capacitive_Injection_Hours
From dbo.Bypass AS bp
Inner Join dbo.Converter AS c On bp.Bypass_ID = c.Bypass_ID
Inner Join dbo.Converter_Tel_Data AS tcon ON c.Converter_ID = tcon.Converter_ID
Where bp.Site_ID = 7
Order By
row_number() over(Partition By bp.Serial_Number Order By tcon.Time_Stamp desc)
This should return the latest row from the tconn table for each bp.Serial_Number.
So, full disclosure, this is my first time using a pivot table and the result set has multiple columns as a result. In this example, we will use the result set without a pivot table applied.
This student has taken multiple courses. What the ideal end result would be, is to count how many courses this student has taken. So if I look I see that the Student has taken Algebra 1 5 times, English 1 2 times and Geometry 2 times.
The Next image is the query with the pivot applied, oh and to make things complicated, its a monster query before trying to attempt the pivot.
So we see in this, that Algebra 1 has a count of 0, Geometry has a count of 2 and English has a count of 0. This is the same query as before but just using this student.

Again, very complicated query before and I'm not clear if I'm using the pivot function correctly.
I'd love to have this pivot with the counts of the courses.
I have a UNION of 3 tables for calculating some balance and I need to get the running SUM of that balance but I can't use PARTITION OVER, because I must do it with a sql query that can work in Access.
My problem is that I cannot use JOIN on an alias subquery, it won't work.
How can I use alias in a JOIN to get the running total?
Or any other way to get the SUM that is not with PARTITION OVER, because it does not exist in Access.
This is my code so far:
SELECT korisnik_id, imePrezime, datum, Dug, Pot, (Dug - Pot) AS Balance
FROM (
SELECT korisnik_id, k.imePrezime, r.datum, SUM(IIF(u.jedinstven = 1, r.cena, k.kvadratura * r.cena)) AS Dug, '0' AS Pot
FROM Racun r
INNER JOIN Usluge u ON r.usluga_id = u.ID
INNER JOIN Korisnik k ON r.korisnik_id = k.ID
WHERE korisnik_id = 1
AND r.zgrada_id = 1
AND r.mesec = 1
AND r.godina = 2017
GROUP BY korisnik_id, k.imePrezime, r.datum
UNION ALL
SELECT korisnik_id, k.imePrezime, rp.datum, SUM(IIF(u.jedinstven = 1, rp.cena, k.kvadratura * rp.cena)) AS Dug, '0' AS Pot
FROM RacunP rp
INNER JOIN Usluge u ON rp.usluga_id = u.ID
INNER JOIN Korisnik k ON rp.korisnik_id = k.ID
WHERE korisnik_id = 1
AND rp.zgrada_id = 1
AND rp.mesec = 1
AND rp.godina = 2017
GROUP BY korisnik_id, k.imePrezime, rp.datum
UNION ALL
SELECT uu.korisnik_id, k.imePrezime, uu.datum, '0' AS Dug, SUM(uu.iznos) AS Pot
FROM UnosUplata uu
INNER JOIN Korisnik k ON uu.korisnik_id = k.ID
WHERE korisnik_id = 1
GROUP BY uu.korisnik_id, k.imePrezime, uu.datum
) AS a
ORDER BY korisnik_id
You can save a query (let's name it Query1) for the UNION of the 3 tables and then create another query that returns each row in the first query and calculates the sum of the rows that are before it (optionally checking that they are in the same group).
It should be something like this:
SELECT *, (
SELECT SUM(Value) FROM Query1 AS b
WHERE b.GroupNumber=a.GroupNumber
AND b.Position<=a.Position
) AS RunningSum
FROM Query1 AS a
However, it's more efficient to do that in the report.
I am VERY new to SQL and self taught. I have two SQL that I stuggled through but got working. Now I need to combine them into one and I'm lost.
SELECT
s.lastfirst,
s.student_number,
SUM(tr.howmany)
FROM
students s
JOIN
truancies tr ON s.id = tr.studentid
WHERE
s.enroll_status = 0 AND
s.schoolid = ~(curschoolid)
GROUP BY
s.lastfirst, s.student_number
HAVING
SUM(tr.howmany) > 0
ORDER BY
s.lastfirst
And this table:
SELECT
S.DCID as DCID,
S.LASTFIRST as LASTFIRST,
S.STUDENT_NUMBER as STUDENT_NUMBER,
S2.FC_SRVC_HRS_DUE as FC_SRVC_HRS_DUE,
CASE
WHEN S2.FC_SRVC_HRS_COMPLETED IS NULL
THEN '0'
ELSE S2.FC_SRVC_HRS_COMPLETED
END AS FC_SRVC_HRS_COMPLETED,
S2.FC_SRVC_HRS_BUYOUT as FC_SRVC_HRS_BUYOUT,
CASE
WHEN S2.FC_SRVC_HRS_COMPLETED IS NULL
THEN S2.FC_SRVC_HRS_DUE * S2.FC_SRVC_HRS_BUYOUT
ELSE ((S2.FC_SRVC_HRS_DUE - S2.FC_SRVC_HRS_COMPLETED) * S2.FC_SRVC_HRS_BUYOUT)
END as Balance_Due
FROM
STUDENTS S, U_STUDENTSUSERFIELDS S2
WHERE
S.DCID = S2.STUDENTSDCID AND
s.enroll_status = 0 AND
s.schoolid = ~(curschoolid) AND
(((S2.FC_SRVC_HRS_DUE - S2.FC_SRVC_HRS_COMPLETED) * S2.FC_SRVC_HRS_BUYOUT) > 0 OR
((S2.FC_SRVC_HRS_DUE - S2.FC_SRVC_HRS_COMPLETED) * S2.FC_SRVC_HRS_BUYOUT) IS NULL) AND
S2.FC_SRVC_HRS_DUE >.1
ORDER BY
s.lastfirst
What I am really looking for are the totals of both of these. I want the SUM(tr.howmany) from the first table and the balance due of the second BUT I need the filters that are in there. This would be sorted by student. I hope I am making sense. Any assistance would be appreciated.
You can join together 2 separate SQL select statements:
Eg:
Select A.id, A.value, B.value
From (select id, count(*) as value from TableA ...) AS A
join (select id, sum(field) as value from TableB ...) AS B
on A.id = B.id
order by A.id
As long as you have a common field to join on this would work. In your case the student_number looks like a good candidate. You will have to do the ordering outside of your subqueries.
I am trying to return a count of tests taken per term. I can get the count to return, but I can't get it grouped by term.
I've tried everything and the closest I get is grouping by term but then my count only = 1, which isn't right.
Here is what I have now. It just returns a count, how do I group it by term_id?
SELECT COUNT(*)
FROM (SELECT DISTINCT ON(student_id, test_event_id, terf.term_id) student_id
FROM report.test_event_result_fact terf
JOIN report.growth_measurement_window gw on gw.term_id = terf.term_id
JOIN report.term t on t.term_id = terf.term_id
JOIN report.test tt on tt.test_id = terf.test_id
WHERE terf.partner_id = 98
AND growth_event_yn = 't'
AND gw.test_window_complete_yn = 't'
AND gw.growth_window_type = 'DISTRICT'
AND tt.test_type_description = 'SURVEY_WITH_GOALS') as TestEvents
Without knowing more about your setup, that's my best bet:
select term_id, count(*) AS count_per_term
from (
select Distinct on (student_id, test_event_id, terf.term_id)
terf.term_id, student_id
from report.test_event_result_fact terf
join report.growth_measurement_window gw using (term_id)
join report.term t using (term_id)
join report.test tt using (term_id)
where terf.partner_id = 98
and growth_event_yn = 't'
and gw.test_window_complete_yn = 't'
and gw.growth_window_type = 'DISTRICT'
and tt.test_type_description = 'SURVEY_WITH_GOALS') as TestEvents
group by 1;
