I am trying a proper logic for stock managment - sql

I have a table StockManagement it looks like this
PId Qty Dateof Booking DateOfReturning
1 5 1 Jan 2013 3 Jan 2013
1 5 1 Jan 2013 4 Jan 2012
Now let's suppose I have 10 quantity of Product A. As my table shows I had Issue 5 Product A from 1 JAn to 3 Jan And another 5 From 1 Jan to 4 Jan .Now My customer want to book Product A from 4 Jan to 7 Jan.As you can see in table the 5 Product A will be return on 3 Jan so I can issue 5 Product from 4 Jan. This is what I want to do through query.
So please help me to get the available quantity between two dates.

select count(s1.qty) from StockManagement s1 inner join
StockManagement s2 on s1.PId=s2.PId
where to_date(s1.DateofBooking,'dd/mm/yyyy') not
between to_date(s2.DateofBooking,'dd/mm/yyyy') and
to_date(s2.DateOfReturning,'dd/mm/yyyy')
Try this. meanwhile I will try to post you a live demo
SQL_LIVE_DEMO

declare #BkDate datetime, #qty int, #Pid int
select #BkDate='04-Jan-2013', #qty=5, #Pid=1
select sum(Qty) AvailableQty
from StockManagement
where
Id=#Pid AND
#BkDate not between DateOfBooking and DateOfReturning
having sum(Qty)>=#qty

SQL: Find number of active "events" each month

Background
I have an SQL table that contains all events, with each event containing a unique identifier.
As you can see for some IDs the "event" stretches across multiple months. What I'm trying to find is the number of "active events" per month.
For example event ID:342, is active in both the month of Jan and Feb. So it should count towards both Jan and Feb's final count.
Example dataset
ID
Start Date
End Date
342
01 Jan 2022
12 Feb 2022
231
12 Feb 2022
26 Feb 2022
123
20 Jan 2022
10 Apr 2022
Desired output:
Month
Start Date
Jan
2
Feb
3
Mar
1
Apr
1
btw: I'm using Alibaba's ODPS SQL and not MySQL or Postgres. So i appreciate if the solution provided could be SQL system agnostic. Thanks!
Here is an example is MySQL 8, using a recursive CTE to construct the list of months. It would be more efficient to use a Calendar Table.
If you are not using MySQL you will need to modify the syntax of the query.
create table dataset(
ID int, Start_date Date,End_date Date);
insert into dataset values
(342,'2022-01-01','2022-02-12'),
(231,'2022-01-12','2022-02-26'),
(123,'2022-01-20','2022-04-10');
/*
Desired output:
Month Start Date
Jan 2
Feb 3
Mar 1
Apr 1
*/

select
min(month(Start_date)),
max(month(End_date))
from dataset;
min(month(Start_date)) | max(month(End_date))
---------------------: | -------------------:
1 | 4
with recursive m as
(select min(month(Start_date)) mon from dataset
union all
select mon + 1 from m
where mon < (select max(month(End_date)) from dataset)
)
select
mon "month",
count(id) "Count"
from m
left join dataset
on month(Start_date)<= mon
and month(End_date) >= mon
group by mon
order by mon;

Aggregate payments per year per customer per type

Please consider the following payment data:
customerID paymentID pamentType paymentDate paymentAmount
---------------------------------------------------------------------
1 1 A 2015-11-28 500
1 2 A 2015-11-29 -150
1 3 B 2016-03-07 300
2 4 A 2015-03-03 200
2 5 B 2016-05-25 -100
2 6 C 2016-06-24 700
1 7 B 2015-09-22 110
2 8 B 2016-01-03 400
I need to tally per year, per customer, the sum of the diverse payment types (A = invoice, B = credit note, etc), as follows:
year customerID paymentType paymentSum
-----------------------------------------------
2015 1 A 350 : paymentID 1 + 2
2015 1 B 110 : paymentID 7
2015 1 C 0
2015 2 A 200 : paymentID 4
2015 2 B 0
2015 2 C 0
2016 1 A 0
2016 1 B 300 : paymentID 3
2016 1 C 0
2016 2 A 0
2016 2 B 300 : paymentID 5 + 8
2016 2 C 700 : paymentId 6
It is important that there are values for every category (so for 2015, customer 1 has 0 payment value for type C, but still it is good to see this).
In reality, there are over 10 payment types and about 30 customers. The total date range is 10 years.
Is this possible to do in only SQL, and if so could somebody show me how? If possible by using relatively easy queries so that I can learn from it, for instance by storing intermediary result into a #temptable.
Any help is greatly appreciated!
a simple GROUP BY with SUM() on the paymentAmount will gives you what you wanted
select year = datepart(year, paymentDate),
customerID,
paymentType,
paymentSum = sum(paymentAmount)
from payment_data
group by datepart(year, paymentDate), customerID, paymentType
This is a simple query that generates the required 0s. Note that it may not be the most efficient way to generate this result set. If you already have lookup tables for customers or payment types, it would be preferable to use those rather than the CTEs1 I use here:
declare #t table (customerID int,paymentID int,paymentType char(1),paymentDate date,
paymentAmount int)
insert into #t(customerID,paymentID,paymentType,paymentDate,paymentAmount) values
(1,1,'A','20151128', 500),
(1,2,'A','20151129',-150),
(1,3,'B','20160307', 300),
(2,4,'A','20150303', 200),
(2,5,'B','20160525',-100),
(2,6,'C','20160624', 700),
(1,7,'B','20150922', 110),
(2,8,'B','20160103', 400)
;With Customers as (
select DISTINCT customerID from #t
), PaymentTypes as (
select DISTINCT paymentType from #t
), Years as (
select DISTINCT DATEPART(year,paymentDate) as Yr from #t
), Matrix as (
select
customerID,
paymentType,
Yr
from
Customers
cross join
PaymentTypes
cross join
Years
)
select
m.customerID,
m.paymentType,
m.Yr,
COALESCE(SUM(paymentAmount),0) as Total
from
Matrix m
left join
#t t
on
m.customerID = t.customerID and
m.paymentType = t.paymentType and
m.Yr = DATEPART(year,t.paymentDate)
group by
m.customerID,
m.paymentType,
m.Yr
Result:
customerID paymentType Yr Total
----------- ----------- ----------- -----------
1 A 2015 350
1 A 2016 0
1 B 2015 110
1 B 2016 300

(We may also want to play games with a numbers table and/or generate actual start and end dates for years if the date processing above needs to be able to use an index)
Note also how similar the top of my script is to the sample data in your question - except it's actual code that generates the sample data. You may wish to consider presenting sample code in such a way in the future since it simplifies the process of actually being able to test scripts in answers.
1CTEs - Common Table Expressions. They may be thought of as conceptually similar to temp tables - except we don't actually (necessarily) materialize the results. They also are incorporated into the single query that follows them and the whole query is optimized as a whole.
Your suggestion to use temp tables means that you'd be breaking this into multiple separate queries that then necessarily force SQL to perform the task in an order that we have selected rather than letting the optimizer choose the best approach for the above single query.

Getting Monthly Data

I want to extract all budget entries charged to the current year and cumulated over each month after .In January, taking the total over January, February take accumulated of January plus accumulated February...
I started with this query :
IF OBJECT_ID('tempdb..#BudgetTransTmp') IS NOT NULL
DROP TABLE #BudgetTransTmp
Select
Row_number() over(ORDER BY YEAR(BTLine.DATE),MONTH(BTLine.DATE)) as RowNumber,
COMBINATION.DISPLAYVALUE,
BTLine.LedgerDimension AS LedgerDimension,
MIN(BTLine.TransactionCurrencyAmount) AS Amount,
SUM(BTLine.TransactionCurrencyAmount)
OVER (ORDER BY YEAR(BTLine.DATE),MONTH(BTLine.DATE),BTLine.LedgerDimension,COMBINATION.DISPLAYVALUE ) AS SUM,
YEAR(BTLine.DATE) AS Year ,
MONTH(BTLine.DATE) AS MONTH
INTO #BudgetTransTmp
FROM MicrosoftDynamicsAX.dbo.BudgetTransactionLine AS BTLine
--Get Display value
INNER JOIN MicrosoftDynamicsAX.dbo.DIMENSIONATTRIBUTEVALUECOMBINATION AS COMBINATION
ON COMBINATION.RECID = BTLine.LEDGERDIMENSION
GROUP BY
BTLine.LedgerDimension,
YEAR(BTLine.DATE),
MONTH(BTLine.DATE)
ORDER BY RowNumber
The result is :
LedgerDimension Amount SUM Year Month Display
1 22565448266 850.00 850.00 2012 8 601200-001-027--
2 22565448265 1700.00 2550.0 2012 12 601200-002-027--
3 22565448266 2700.00 5250.00 2012 12 601200-001-027--
4 22565448267 650.00 5900.00 2012 12 601400-002-027--
5 22565448268 1100.00 7000.00 2012 12 601400-001-027--
But i want to get
LedgerDimension Amount SUM Year Month Display
1 22565448266 850.00 850.00 2012 8 601200-001-027--
2 22565448265 1700.00 1700.0 2012 12 601200-002-027--
3 22565448266 2700.00 3350.00 2012 12 601200-001-027--
4 22565448267 650.00 650.00 2012 12 601400-002-027--
5 22565448268 1100.00 1100.00 2012 12 601400-001-027--
I think my COMBINATION of ORDER by (primary key) must be betwwen LedgerDimension ,Year , Month , Display
Any help in this regards
I think what you need to do is:
SUM(BTLine.TransactionCurrencyAmount)
OVER (PARTITION BY BTLine.LedgerDimension ORDER BY YEAR(BTLine.DATE),MONTH(BTLine.DATE),BTLine.LedgerDimension,COMBINATION.DISPLAYVALUE ) AS SUM
let me know if this works.

How to inserting an intermediate row?

I have the following table:
Year Line January Febraury March .... December
2011 B1 5 10 20
2012 B1 10 15 25 ...
2011 A1 4 8 10 ...
And I want to insert a subtotal row each two lines (if exists), in particular each time year and Line changing: so
Year Line January Febraury March .... December
2011 B1 5 10 20
2012 B1 10 15 25 ...
--- B1 +100% +50% +25% ..
2011 A1 4 8 10 ...
How can I do this in T-SQL ?
Maybe using cursor ?
Are you certain that you want to insert a new row? Or just be able to calculate that subtotal when you query the data?

SELECT
Year,

SUM(January) AS January,
SUM(February) AS February,

EDIT Follow question edit
I strongly suggest that you mean a query, not a change to the actual data. I also suggest that you either build these lines in your reporting environment, or you put the % values to the right of each record...
SELECT
this_year.Year,
this_year.Line,
this_year.January,
CAST(this_year.January AS DECIMAL(8,2)) / CAST(last_year.January AS DECIMAL(8,2)) AS January_Change,
...
FROM
yourTable AS this_year
LEFT JOIN
yourTable AS last_year
ON last_year.year = this_year.year-1
AND last_year.line = this_year.line

Running total by grouped records in table
I am trying to put together an SQL statement that returns the SUM of a value by month, but on a year to date basis. In other words, for the month of March, I am looking to get the sum of a value for the months of January, February, and March.
I can easily do a group by to get a total for each month by itself, and potentially calculate the year to date value I need in my application from this data by looping through the results set. However, I was hoping to have some of this work handled with my SQL statement.
Has anyone ever tackled this type of problem with an SQL statement, and if so, what is the trick that I am missing?
My current sql statement for monthly data is similar to the following:
Select month, year, sum(value) from mytable group by month, year
If I include a where clause on the month, and only group by the year, I can get the result for a single month that I am looking for:
select year, sum(value) from mytable where month <= selectedMonth group by year
However, this requires me to have a particular month pre-selected or to utilize 12 different SQL statements to generate one clean result set.
Any guidance that can be provided would be greatly appreciated!
Update: The data is stored on an IBM iSeries.
declare #Q as table
(
mmonth INT,
value int
)
insert into #Q
values
(1,10),
(1,12),
(2,45),
(3,23)
select sum(January) as UpToJanuary,
sum(February)as UpToFebruary,
sum(March) as UpToMarch from (
select
case when mmonth<=1 then sum(value) end as [January] ,
case when mmonth<=2 then sum(value) end as [February],
case when mmonth<=3 then sum(value) end as [March]
from #Q
group by mmonth
) t
Produces:
UpToJanuary UpToFebruary UpToMarch
22 67 90
You get the idea, right?
NOTE: This could be done easier with PIVOT tables but I don't know if you are using SQL Server or not.
As far as I know DB2 does support windowing functions although I don't know if this is also supported on the iSeries version.
If windowing functions are supported (I believe IBM calls them OLAP functions) then the following should return what you want (provided I understood your question correctly)
select month,
year,
value,
sum(value) over (partition by year order by month asc) as sum_to_date
from mytable
order by year, month
create table mon
(
[y] int not null,
[m] int not null,
[value] int not null,
primary key (y,m))
select a.y, a.m, a.value, sum(b.value)
from mon a, mon b
where a.y = b.y and a.m >= b.m
group by a.y, a.m, a.value
2011 1 120 120
2011 2 130 250
2011 3 500 750
2011 4 10 760
2011 5 140 900
2011 6 100 1000
2011 7 110 1110
2011 8 90 1200
2011 9 70 1270
2011 10 150 1420
2011 11 170 1590
2011 12 600 2190
You should try to join the table to itself by month-behind-a-month condition and generate a synthetic month-group code to group by as follows:
select
sum(value),
year,
up_to_month
from (
select a.value,
a.year,
b.month as up_to_month
from table as a join table as b on a.year = b.year and b.month => a.month
)
group by up_to_month, year
gives that:
