I have question regarding how to make a calculated pivot table from several query results on PostgreSQL. I've managed to make three queries results but don't have any idea how to combine and calculate all the data into a single table. I've tried to google it but found out that most of the question is about how to make a pivot table from a single table, which I'm able to do using sum, case, and group by. Well, Here's the simplified version of my query results
Query from query 1 which contains gross value
| city | code | gross |
|-------|------|--------|
| city1 | 21 | 194793 |
| city1 | 25 | 139241 |
| city1 | 28 | 231365 |
| city2 | 21 | 282025 |
| city2 | 25 | 334458 |
| city2 | 28 | 410852 |
| city3 | 21 | 109237 |
Result from query 2 which contains positive adjustments
| city | code | adj_pos |
|-------|------|---------|
| city1 | 21 | 16259 |
| city1 | 25 | 13634 |
| city1 | 28 | 45854 |
| city2 | 25 | 18060 |
| city2 | 28 | 18220 |
Result from query 3 which contains negative adjustments
| city | code | adj_neg |
|-------|------|---------|
| city1 | 25 | 23364 |
| city2 | 21 | 27478 |
| city2 | 25 | 23474 |
And what I want to to is to create something like this
| city | 21_gross | 25_gross | 28_gross | 21_pos | 25_pos | 28_pos | 21_neg | 25_neg | 28_neg |
|-------|----------|----------|----------|--------|--------|--------|--------|--------|--------|
| city1 | 194793 | 139241 | 231365 | 16259 | 13634 | 45854 | | 23364 | |
| city2 | 282025 | 334458 | 410852 | | 18060 | 18220 | 27478 | 23474 | |
| city3 | 109237 | | | | | | | | |
or probably final calculation which come from gross + positive adjustment -
negative adjustment from each city on each code like this
| city | 21_nett | 25_nett | 28_nett |
|-------|---------|---------|---------|
| city1 | 211052 | 129511 | 277219 |
| city2 | 254547 | 329044 | 429072 |
| city3 | 109237 | 0 | 0 |
Any suggestion will be appreciated. Thank you!
I think the best you can achieve is to get the pivoting part as JSON - http://sqlfiddle.com/#!17/b7d64/23:
select
city,
json_object_agg(
code,
coalesce(gross,0) + coalesce(adj_pos,0) - coalesce(adj_neg,0)
) as js
from q1
left join q2 using (city,code)
left join q3 using (city,code)
group by city

I'm trying to generate a serial number based on a few conditions.
My dataset:
+--------+------------+------------+---------+--------+
| Client | Start_Date | End_date | Product | Ser_No |
+--------+------------+------------+---------+--------+
| 44 | 22-01-2018 | 31-12-2018 | A | |
+--------+------------+------------+---------+--------+
| 44 | 24-02-2018 | 01-01-2019 | B | |
+--------+------------+------------+---------+--------+
| 44 | 12-03-2018 | 01-01-2019 | C | |
+--------+------------+------------+---------+--------+
| 100 | 24-01-2018 | 30-11-2018 | A | |
+--------+------------+------------+---------+--------+
| 100 | 26-01-2018 | 15-12-2018 | D | |
+--------+------------+------------+---------+--------+
| 100 | 26-01-2018 | 01-02-2019 | E | |
+--------+------------+------------+---------+--------+
| 100 | 01-03-2018 | 31-01-2019 | F | |
+--------+------------+------------+---------+--------+
What I did to configure my serial number:
RANK() OVER(PARTITION BY Client ORDER BY Client, Start_date ASC)
So now it generates a serial number for my which looks like this:
+--------+------------+------------+---------+--------+
| Client | Start_Date | End_date | Product | Ser_No |
+--------+------------+------------+---------+--------+
| 44 | 22-01-2018 | 31-12-2018 | A | 1 |
+--------+------------+------------+---------+--------+
| 44 | 24-02-2018 | 01-01-2019 | B | 2 |
+--------+------------+------------+---------+--------+
| 44 | 12-03-2018 | 01-01-2019 | C | 3 |
+--------+------------+------------+---------+--------+
| 100 | 24-01-2018 | 30-11-2018 | A | 1 |
+--------+------------+------------+---------+--------+
| 100 | 26-01-2018 | 15-12-2018 | D | 2 |
+--------+------------+------------+---------+--------+
| 100 | 26-01-2018 | 01-02-2019 | E | 2 |
+--------+------------+------------+---------+--------+
| 100 | 01-03-2018 | 31-01-2019 | F | 4 |
+--------+------------+------------+---------+--------+
What goes wrong for my analysis is the last line, it generates the serial number. What it has to be is 3.
Can anayone help me to generate it in this order?
Thanks in advance!
Extra
In addition to my question from yesterday, there is something extra that I need to do. Because the Ser_No has to be the same when my Start_Date is the same, but the Ser_No has also be the same when my folowing records is the same product (also when it has a different Start_Date)
So what I I expect and what I get right now:
+--------+------------+------------+---------+--------+------------+
| Client | Start_Date | End_date | Product | Ser_No | Ser_No New |
+--------+------------+------------+---------+--------+------------+
| 44 | 22-01-2018 | 31-12-2018 | A | 1 | 1 |
+--------+------------+------------+---------+--------+------------+
| 44 | 24-02-2018 | 01-01-2019 | B | 2 | 2 |
+--------+------------+------------+---------+--------+------------+
| 44 | 12-03-2018 | 01-01-2019 | C | 2 | 2 |
+--------+------------+------------+---------+--------+------------+
| 100 | 24-01-2018 | 30-11-2018 | A | 1 | 1 |
+--------+------------+------------+---------+--------+------------+
| 100 | 26-01-2018 | 15-12-2018 | D | 2 | 2 |
+--------+------------+------------+---------+--------+------------+
| 100 | 26-01-2018 | 01-02-2019 | E | 2 | 2 |
+--------+------------+------------+---------+--------+------------+
| 100 | 01-03-2018 | 31-01-2019 | F | 3 | 3 |
+--------+------------+------------+---------+--------+------------+
| 100 | 11-04-2018 | 31-03-2019 | F | 4 | 3 |
+--------+------------+------------+---------+--------+------------+
| 100 | 20-04-2018 | 31-01-2019 | G | 5 | 4 |
+--------+------------+------------+---------+--------+------------+
| 100 | 21-04-2018 | 31-01-2019 | A | 6 | 5 |
+--------+------------+------------+---------+--------+------------+
| 100 | 21-04-2018 | 31-01-2019 | B | 6 | 5 |
+--------+------------+------------+---------+--------+------------+
| 100 | 01-05-2018 | 31-01-2019 | B | 7 | 5 |
+--------+------------+------------+---------+--------+------------+
Any idea on how to achieve this, because I won't get it
You need to use DENSE_RANK instead:
This function returns the rank of each row within a result set partition, with no gaps in the ranking values.
DENSE_RANK() OVER(PARTITION BY Client ORDER BY Start_date) AS Ser_no
Additionaly the Client in ORDER BY has no effect because it has the same value per partition.
Suppose such a spreadsheet in org table
|------------+-------+------------+--------+--------+------------|
| Date | Items | Unit Price | Amount | Amount | Categories |
|------------+-------+------------+--------+--------+------------|
| 2019/09/17 | A | 2.64 | 1 | 2.64 | materials |
| | B | 52.67 | 2 | 105.34 | diagnosis |
| | C | 3.08 | 1 | 3.08 | materials |
| | D | 3.85 | 2 | 7.7 | materials |
| | E | 33.66 | 2 | 67.32 | materials |
| | F | 40 | 1 | 40 | treatments |
| | G | 16.5 | 1 | 16.5 | materials |
| | H | 4 | 3 | 12 | treatments |
| | I | 40 | 1 | 40 | bed |
| x | M | 6 | 13 | 78 | treatments |
|------------+-------+------------+--------+--------+------------|
#+TBLFM: $5=$3*$4
I want to sum up the material fees.
Is it possible to calculate it by grouping like vsum(where Categories == materials)?
One way to do this with an elisp expression will be:
|------------+-------+------------+--------+--------+------------|
| Date | Items | Unit Price | Amount | Amount | Categories |
|------------+-------+------------+--------+--------+------------|
| 2019/09/17 | A | 2.64 | 1 | 2.64 | materials |
| | B | 52.67 | 2 | 105.34 | diagnosis |
| | C | 3.08 | 1 | 3.08 | materials |
| | D | 3.85 | 2 | 7.7 | materials |
| | E | 33.66 | 2 | 67.32 | materials |
| | F | 40 | 1 | 40 | treatments |
| | G | 16.5 | 1 | 16.5 | materials |
| | H | 4 | 3 | 12 | treatments |
| | I | 40 | 1 | 40 | bed |
| x | M | 6 | 13 | 78 | treatments |
|------------+-------+------------+--------+--------+------------|
| TOTAL: | | | | 97.24 | |
|------------+-------+------------+--------+--------+------------|
#+TBLFM: $5=$3*$4
#+TBLFM: #12$5='(apply #'+ (cl-mapcar (lambda (num category) (if (eq category 'materials) num 0)) '(#II$5..#III$5) '(#II$6..#III$6)));L
cl-mapcar applies + to cell #12$5 by comparing the list which is column 6 to symbol'materials.

I am trying to understand how to pivot data within T-SQL but can't seem to get it working. I have the following table structure
+-------------------+-----------------------+
| Name | Value |
+-------------------+-----------------------+
| TaskId | 12417 |
| TaskUid | XX00044497 |
| TaskDefId | 23 |
| TaskStatusId | 4 |
| Notes | |
| TaskActivityIndex | 0 |
| ModifiedBy | Orange |
| Modified | /Date(1554540200000)/ |
| CreatedBy | Apple |
| Created | /Date(2121212100000)/ |
| TaskPriorityId | 40 |
| OId | 2 |
+-------------------+-----------------------+
I want to pivot the name column to be columns expected output
+--------+------------------------+-----------+--------------+-------+-------------------+------------+-----------------------+-----------+-----------------------+----------------+-----+
| TASKID | TASKUID | TASKDEFID | TASKSTATUSID | NOTES | TASKACTIVITYINDEX | MODIFIEDBY | MODIFIED | CREATEDBY | CREATED | TASKPRIORITYID | OID |
+--------+------------------------+-----------+--------------+-------+-------------------+------------+-----------------------+-----------+-----------------------+----------------+-----+

+--------+------------------------+-----------+--------------+-------+-------------------+------------+-----------------------+-----------+-----------------------+----------------+-----+
Is there an easy way of doing it? The columns are fixed (not dynamic).
Any help appreciated
Try this:
select * from yourtable
pivot
(
min(value)
for Name in ([TaskID],[TaskUID],[TaskDefID]......)
) as pivotable
You can also use case statements.
You must use the aggregate function in the pivot table.

I am a novice self-teaching Microsoft Access.
I have an MS Access database with a table of students (Table1).
Table1
+----+-----------+----------+------------+------------+
| id | firstname | lastname | Year_Group | Form_Group |
+----+-----------+----------+------------+------------+
| 2 | mnb | nbgfv | 7 | 1 |
| 3 | jhg | uhgf | 8 | 2 |
| 4 | poi | ijuy | 9 | 2 |
| 5 | tgf | tgfd | 10 | 2 |
| 6 | wer | qwes | 11 | 2 |
+----+-----------+----------+------------+------------+
Every day students days are recorded sort of like Table2.
Table2
+----------+----+-----------+----------+------------+--------+-----------+----------+
| Date | id | firstname | lastname | Year_Group | Effort | Behaviour | Homework |
+----------+----+-----------+----------+------------+--------+-----------+----------+
| 28/02/19 | 2 | mnb | nbgfv | 7 | Good | Good | Y |
| 28/02/19 | 3 | jhg | uhgf | 8 | OK | OK | Y |
| 28/02/19 | 4 | poi | ijuy | 9 | Bad | Bad | N |
| 01/03/19 | 5 | tgf | tgfd | 10 | Good | OK | Y |
| 01/03/19 | 6 | wer | qwes | 11 | Good | Good | Y |
+----------+----+-----------+----------+------------+--------+-----------+----------+
Is there a way (when using a list box or combo box) to select a student from Table1 so that their information is used for the corresponding columns in Table2?
Or is there a more efficient way to do this?
Firstly, you should normalise your data.
Currently, you are repeating the firstname, lastname, and Year_Group data in two separate tables, which not only bloats your database, but also means that such data must be maintained in two separate places, potentially leading to inconsistencies and then uncertainty as to which is the master.
Instead, I would suggest that your Students table should contain all information pertaining to the characteristics of a student:
Students
+----+-----------+----------+------------+------------+
| id | firstname | lastname | Year_Group | Form_Group |
+----+-----------+----------+------------+------------+
| 2 | mnb | nbgfv | 7 | 1 |
| 3 | jhg | uhgf | 8 | 2 |
| 4 | poi | ijuy | 9 | 2 |
| 5 | tgf | tgfd | 10 | 2 |
| 6 | wer | qwes | 11 | 2 |
+----+-----------+----------+------------+------------+
And the information pertaining to each school day should only reference the student ID in the Students table:
SchoolDays
+----------+----+--------+-----------+----------+
| Date | id | Effort | Behaviour | Homework |
+----------+----+--------+-----------+----------+
| 28/02/19 | 2 | Good | Good | Y |
| 28/02/19 | 3 | OK | OK | Y |
| 28/02/19 | 4 | Bad | Bad | N |
| 01/03/19 | 5 | Good | OK | Y |
| 01/03/19 | 6 | Good | Good | Y |
+----------+----+--------+-----------+----------+
Then, if you want to display the data in its entirety, you would use a query which joins the two tables, e.g.:
select
t2.date,
t1.firstname,
t1.lastname,
t1.year_group,
t2.effort,
t2.behaviour,
t2.homework
from
students t1 inner join schooldays t2 on t1.id = t2.id
I have two objects within a SQl Server 2008 R2 database, which I am trying to join together with a left join but I am unable to get the left join to return all records from the table.
1 table - tt_activityoccurrence
1 view - vw_academicweeks
The vw_academicweeks, is a view that contains for each academic year a week number, and the first day and last day of the week and contains 52 records for each academic year.
tt_activityoccurrence is a table which contains occurrences of lessons within a year, lessons will not occur in all 52 weeks of the year.
With my query I am trying to return all instances from the vw_academicweeks view to return the following information
+------------+------------+------------+------------+---------+
| ActivityID | WeekStart | StartTime | EndTime | week_no |
+------------+------------+------------+------------+---------+
| 59936 | 04/09/2017 | 05/09/2017 | 05/09/2017 | 6 |

With the left join I can return all values except the nulls, so that the week_no column is missing rows, 13,22 and 23. I have also tried this with an outer join but receive the same information.
I feel I am missing something obvious but it is escaping me at the moment.
select
ttao.ActivityID
,dateadd(dd,datediff(dd,0,DATEADD(dd, -(DATEPART(dw, ttao.StartTime)-1), ttao.StartTime)),0) WeekStart

,aw.week_no
from
vw_AcademicWeeks AW
left join TT_ActivityOccurrence TTAO on

order by aw.week_no asc
Your where clause makes it an inner join by eliminating rows outside of the scope of your join. You need to move this logic up to your join statement. Note, I didn't validate your join condiditon (the dateadd...datediff logic)
select
ttao.ActivityID
