I'm trying to extract the stock in an specific date. To do so, I'm doing a cumulative of stock movements by date, product and warehouse.
select m.codart AS REF,
m.descart AS 'DESCRIPTION',
m.codalm AS WAREHOUSE,
m.descalm AS WAREHOUSEDESCRIP,
m.unidades AS UNITS,
m.entran AS 'IN',
m.salen AS 'OUT',
m.entran*1 + m.salen*-1 as MOVEMENT,
(select sum(m1.entran*1 + m1.salen*-1)
from MOVSTOCKS m1
where m1.codart = m.codart and m1.codalm = m.codalm and m.fecdoc >= m1.fecdoc) as 'CUMULATIVE',
m.PRCMEDIO as 'VALUE',
m.FECDOC as 'DATE',
m.REFERENCIA as 'REF',
m.tipdoc as 'DOCUMENT'
from MOVSTOCKS m
where (m.entran <> 0 or m.salen <> 0)
and (select max(m2.fecdoc) from MOVSTOCKS m2) < '2020-11-30T00:00:00.000'
order by m.fecdoc
Without the and (select max(m2.fecdoc) from MOVSTOCKS m2) < '2020-11-30T00:00:00.000' it shows data like this, which is ok.
REF WAREHOUSE UNITS IN OUT MOVEMENT CUMULATIVE DATE
1 0 2 0 2 -2 -7 2020-11-25
1 1 3 0 3 -3 -3 2020-11-25
1 0 5 0 5 -5 -7 2020-11-25
1 0 9 9 0 9 2 2020-11-26
2 0 2 2 0 2 2 2020-11-26
1 0 1 1 0 1 3 2020-12-01
The problem is, with the subselect in the where clause it returns no results (I think it is because it just looks for the max date and says it is bigger than 2020-11-30). I would like it to show the closest dates (all of them, for each product and warehouse) to the selected one, in this case 2020-11-30.
It should look slike this:
REF WAREHOUSE UNITS IN OUT MOVEMENT CUMULATIVE DATE
1 1 3 0 3 -3 -3 2020-11-25
1 0 9 9 0 9 2 2020-11-26
2 0 2 2 0 2 2 2020-11-26
Sorry if I'm not clear. Ask me if I have to clarify anything
Thank you
I am guessing that you want something like this:
select t.*
from (select m.*,
sum(m.entran - m1.salen) over (partition by m.codart, m.codalm order by fecdoc) as cumulative,
max(fecdoc) over (partition by m.codart, m.codalm) as max_fecdoc
from MOVSTOCKS m
where fecdoc < '2020-11-30'
) m
where fecdoc = max_fecdoc;
The subquery calculates the cumulative amount of stock using window functions and filters for records before the cutoff date. The outer query selects the most recent record from the combination of codeart/codalm, which seems to be how you are identifying a product.

Seeking some help after spending alot of time on searching but to no avail and decided to post this here as I'm rather new to SQL, so any help is greatly appreciated. I've tried a few functions but can't seem to get it right. e.g. GROUP BY, BETWEEN etc
On the PrestoSQL server, I have a table as shown below starting with columns Date, ID and COVID. Using GROUP BY ID, I would like to create a column EverCOVIDBefore which looks back at all past dates of the COVID column to see if there was ever COVID = 1 or not, as well as another column called COVID_last_2_mth which checks if there was ever COVID = 1 within the past 2 months
(Highlighted columns are my expected outcomes)
Link to dataset: https://drive.google.com/file/d/1Sc5Olrx9g2A36WnLcCFMU0YTQ3-qWROU/view?usp=sharing
You can do:
select *,
max(covid) over(partition by id order by date) as ever_covid_before,
max(covid) over(partition by id order by date
range between interval '2 month' preceding and current row)
as covid_last_two_months
from t
Result:
date id covid ever_covid_before covid_last_two_months

I need to create 2 cumulative sums based on the value type, for example:
I have values of incoming stock units from 2 types: A and B. and I also have records of outgoing stock units.
If we have enough stock of type "A" it should taken out of type A, if not- it should be taken out of type B. so basically I need to crate the columns "A stock" and "B stock" below, representing the current balance of each type.
I tried using cumulative sum but I'm having trouble with the condition... is there a way to write this query without using a loop ? ( Vertica DB)
In table below A_stock and B_stock are the final result I need to create
ID Type In OUT A stock B stock Order_id
1 A 100 0 100 0 1
1 B 50 0 100 50 2
1 A 100 0 200 50 3
1 - 0 -200 0 50 4
1 - 0 -10 0 40 5
1 B 50 0 0 90 6
1 A 40 0 40 90 7
1 - 0 -20 20 90 8
2 A 30 0 30 0 1
2 B 20 0 30 20 2
2 A 10 0 40 20 3
2 - 0 -20 20 20 4
You can use window functions - but you need a column that defines the ordering of the rows, I assumed ordering_id:
select t.*,
sum(case when type = 'A' then in + out else 0 end) over(partition by id order by ordering_id) a_stock,
sum(case when type = 'B' then in + out else 0 end) over(partition by id order by ordering_id) b_stock
from mytable t
This assumes that you want the stock on a per-id basis; if that's not the case, just remove the partition clause from the over() clause.
This is a simplification of the table q3 I'm working with:
Partno EndOfMonth AA AS EA ES
a 31.5.2017 5 1 0 1
b 31.5.2017 3 1 0 1
c 31.5.2017 2 2 0 1
a 31.6.2017 1 2 2 2
b 31.6.2017 1 0 1 2
c 31.6.2017 2 3 1 4
a 31.7.2017 4 3 2 0
b 31.7.2017 3 0 6 0
c 31.7.2017 4 1 0 0
I need to sum the numbers in the last four columns for each part in Partno so that the sum represents the running total of the last three months at each date in the EndOfMonth column.
The result i'm looking for is:
Partno EndOfMonth AA AS EA ES
a 31.5.2017 5 1 0 1
b 31.5.2017 3 1 0 1
c 31.5.2017 2 2 0 1
a 31.6.2017 6 3 2 3
b 31.6.2017 6 1 1 3
c 31.6.2017 4 5 1 5
a 31.7.2017 10 6 4 3
b 31.7.2017 7 1 7 3
c 31.7.2017 8 6 1 5
So e.g. for partno A at 31.7.2017 the last thee months' sum for the 'AA' column is 4+1+5=10.
I'm quite new to SQL and am well and truly stuck with this. I've tried something like the following to just get a simple rolling total (without even specifying the sum range to be the last 3 months). Also, I'm not sure if the database even supports all the functions in the below code, since it's giving me the error "Incorrect Syntax near the keyword 'OVER'"
SELECT
Partno,
EndofMonth,
SUM(q3.AA) OVER (PARTITION BY q3.Partno ORDER BY EndofMonth ROWS UNBOUNDED PRECEDING) as 'AA'
FROM q3
Anyway, any help would be greatly appreciated!
Thanks
EDIT:
Thanks to Benjamin and with a little help from this post: https://dba.stackexchange.com/questions/114403/date-range-rolling-sum-using-window-functions
I was able to find the solution:
SELECT a.Partno, a.EndofMonth, SUM(b.AA) as 'AA', SUM(b.AS) as 'AS',...
FROM q3 a, q3 b
WHERE a.Partno = b.Partno AND a.endOfMonth >= b.endOfMonth
AND b.endOfMonth >= DATEADD(month,-2,a.endOfMonth)
GROUP BY a.Partno, a.endOfMonth
Something like this might work:
SELECT a.Partno, a.EndofMonth, SUM(b.AA) as AA
FROM q3 a, q3 b
WHERE a.Partno = b.Partno
AND DATEDIFF(month, b.endOfMonth, a.endOfMonth) < 4
GROUP BY a.Partno, b.Partno
This assumes that endOfMonth is in datetime format, if it is not you will have to use convert(). Note that you might have to replace DATEDIFF() depending on what implementation you are using.
I haven't tested this, so I might be way off. It has been a while since I worked with SQL. Hopefully you can get it working by messing around with it a bit, and if not then maybe it will inspire you to write something better. Let me know how it goes!
I work for a small company and we're trying to get away from Excel workbooks for Inventory control. I thought I had it figured out with help from (Nasser) but its beyond me. This is what I can get into a table, from there I need too get it to look like the table below.

The first record of a group would be considered the opening balance. Inventory going into the yard have the ID of 1 and out of the yard are 2's. Load footage going into the yard always has a load cost per foot and I can calculate the the running total of footage. The first record of a group is easy to calculate the run cost and run cost per foot. The next record becomes a little more difficult to calculate. I need to move the average of run cost per foot forward to the load cost per foot when something is going out of the yard and then calculate the run cost and average run cost per foot again. Hopefully this makes sense to somebody and we can automate some of these calculations. Thanks for any help.

Let me say first off three things:
This is certainly not the best way to do it. There is a rule saying that if you need a while-loop, then you are most probably doing something wrong.
I suspect there is some calculation errors in your original "Expected output", please check the calculations since my calculated values are different according to your formulas.
This question could also be seen as a gimme teh codez type of question, but since you asked a decently formed question with some follow-up research, my answer is below. (So no upvoting since this is help for a specific case)
Now onto the solution:
I attempted to use my initial hint of the LAG statement in a nicely formed single update statement, but since you can only use a windowed function (aka LAG) inside a select or order by clause, that will not work.
What the code below does in short:
It calculates the various calculated fields for each record when they can be calculated and with the appropriate functions, updates the table and then moves onto the next record.
Please see comments in the code for additional information.
TempTable is a demo table (visible in the linked SQLFiddle).
Please read this answer for information about decimal(19, 4)

If you are unclear about parts of the code, I can update with additional explanations.
So I have data like this:
Date EMPLOYEE_ID HEADCOUNT TERMINATIONS
1/31/2011 1 1 0
2/28/2011 1 1 0
3/31/2011 1 1 0
4/30/2011 1 1 0
...
1/31/2012 1 1 0
2/28/2012 1 1 0
3/31/2012 1 1 0
1/31/2012 2 1 0
2/28/2011 2 1 0
3/31/2011 2 1 0
4/30/2011 2 0 1
1/31/2012 3 1 0
2/28/2011 3 1 0
3/31/2011 3 1 0
4/30/2011 3 1 0
...
1/31/2012 3 1 0
2/28/2012 3 1 0
3/31/2012 3 1 0
And I want to sum up the headcount, but I need to remove the duplicate entries from the sum by the employee_id. From the data you can see employee_id 1 occurs many times in the table, but I only want to add its headcount column once. For example if I rolled up on year I might get a report using this query:
with member [Measures].[Distinct HeadCount] as
??? how do I define this???
select { [Date].[YEAR].children } on ROWS,
{ [Measures].[Distinct HeadCount] } on COLUMNS
from [someCube]
It would product this output:
YEAR Distinct HeadCount
2011 3
2012 2
Any ideas how to do this with MDX? Is there a way to control which row is used in the sum for each employee?
You can use an expression like this:
WITH MEMBER [Measures].[Distinct HeadCount] AS
Sum(NonEmpty('the set of the employee ids', 'all the dates of the current year (ie [Date].[YEAR].CurrentMember)'), [Measures].[HeadCount])
If you want a more generic expression you can use this:
WITH MEMBER [Measures].[Distinct HeadCount] AS
Sum(NonEmpty('the set of the employee ids',
Descendants(Axis(0).Item(0).Item(0).Hierarchy.CurrentMember, Axis(0).Item(0).Item(0).Hierarchy.CurrentMember.Level, LEAVES)),
IIf(IsLeaf(Axis(0).Item(0).Item(0).Hierarchy.CurrentMember),
[Measures].[HeadCount],
NULL))
