MDX how retrieve first order date as a dimension - ssas

How to create a dimension that would group users by the date of the first order.
Example initial table:
UserId | OrderDate | OrderAmount
1 2012 100
1 2013 100
2 2013 100
2 2014 100
Retrieving the first order date is fairly easy
FILTER([Date].[OrderDate].MEMBERS, [Measures].[OrderAmount]).ITEM(0).NAME
But how create a dimension so the result rows would be grouped by the date of first order.
OrderDate
First order date
(orders)
xxxx 2012 2013 2014
2012 100
2013 100 100 100

Detect and Set Column values between rows

I have a table relating to products:
PRD_SLD table
ID DATE SALE_IND
3 2012 0
3 2013 0
3 2014 1
3 2014 1
3 2015 1
3 2016 0
3 2017 1
I would like my final results to look like this:
PRD_SLD table
ID DATE SALE_IND STRT END
3 2012 0 2012 2014
3 2013 0 2012 2014
3 2014 1 2014 2016
3 2014 1 2014 2016
3 2015 1 2014 2016
3 2016 0 2016 2017
3 2017 1 2017 2017
I currently have a working CTE for retrieving the rows in which the values change. this CTE returns this:
PRD_SLD table
ID DATE SALE_IND
3 2012 0
3 2014 1
3 2016 0
3 2017 1
So it returns the first instance of the value in the table, and returns every time the SALE_IND changes.
Is there a way to create a start and end date based off of the date column? I am still very new to this and was enrolled in an advanced course. I'm sure there is a better way to complete this but is there a way to do it with the CTE results i have created? I know there is a between function but i don't know how to implement it into this query
One method is to define groups of adjacent records. You don't have a solid ordering of the rows, but you do have just enough information for this to work -- assuming the indicator is constant in each year.
select t.*,
min(year) over (partition by id, sale_ind, seqnum - seqnum_s) as min_year,
max(year) over (partition by id, sale_ind, seqnum - seqnum_s) as max_year
from (select t.*,
dense_rank() over (partition by id order by date) as seqnum,
dense_rank() over (partition by id, sale_ind order by date) as seqnum_s
from t
) t;

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
1 C 2015 0
1 C 2016 0

(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 the max from two combined columns

I'm trying to get the value from all accounts in use, using the combination of two columns (Year and month) to get the right period.
The data table looks like this:

Table: AcBal
I've tried to make an query, but somehow, I cant quite get there...
Select Account,
Year,
Month,
MAX(((Year*100)+Month)) AS YearPeriod,
Value
from AcBal
where YearPeriod <= 201601
group by Account, Year, Month, Value
order by Account, Year
If I use "where year <= 2017", then I get a result, but with multiple hits for each accout. I only want one result for each account.
Wanted result:
Account
Year
Month
Value
1000
2016
1
11111
2000
2014
12
22222
3000
2015
1
33333
4000
2016
1
44444
How can I achieve that?
You could use TOP (1) WITH TIES and ROW_NUMBER() OVER() like the following query
Select TOP (1) WITH TIES
Account, [Year], [Month], [Year]*100+[Month] AS YearPeriod , Value
from AcBal
where [Year]*100+[Month] <=201601
ORDER BY ROW_NUMBER() OVER(PARTITION BY Account ORDER BY [Year]*100 +[Month] DESC)
Demo link: http://rextester.com/DUPJ25770
Use HAVING:
Select Account, Year, Month, MAX(((Year*100)+Month)) AS YearPeriod , Value
from AcBal
group by Account, Year, Month, Value
Having MAX(((Year*100)+Month)) <=201601
order by Account, Year

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.

Getting a variable end of year date and value from MS Access table using SQL

I have some data is that is daily (day on day) closing figures for a tracked supply and is in one MS Access table that has 2 columns - Dates (the date), PXLast(the day's closing figure)).
I have daily data from Jan 1991 to Aug 2013 and I wanted to get the percentage change of PXLast at every year end compared to last year year end as follows:
Year | Percentage Change of PXLast(Year on Year)
1991 | 15.2%
1992 | 9.2%
The year end date varies (not always 31st ) and I am going about getting the last PXLast value by:
1.Get the max date in Dec every year: results in MyYear, MyMonth, MyDay
2.Combine it using DateSerial(MyYear, MyMonth, MyDay)
3.Join the resulting query to the table and inner join on the date column
4.Get the PXLast value
SELECT EndDates.EndDates, NSE20.PX_LAST AS LookPoint
FROM NSE20 INNER JOIN
(SELECT DateSerial([MyYear],[MyMonth],[MyDay])
AS EndDates FROM (SELECT 12 AS MyMonth, MyDay, MyYear FROM
(SELECT Max(Day([Dates])) AS MyDay, Year([Dates]) AS MyYear
FROM NSE20 WHERE (((Month([Dates]))=12))
GROUP BY Year([Dates])) AS EndYearValues)
AS EndValueDates)
AS EndDates ON NSE20.Dates = EndDates.EndDates;
Could anyone assist me get the corresponding value using a query for previous year end
eg for 29 Dec 2006, it should show the current value and show the value for 31 Dec 2005
in the same row ie
Year | Current Year End| Previous Year End
2005 | 3449.00 | 4611.19
2006 | 9.2% |3449.00
Any help is appreciated.
Any suggestions to a better way of doing this is very very welcome....
Let's assume that you have some test data in a table named [NSE20] that looks like this
Dates PXLast
---------- ------
2010-07-01 131
2010-12-31 130
2011-11-12 123
2011-12-30 125
2012-01-03 127
2012-12-31 129
I'd start by creating a saved query in Access named [NSE20_year_ends] that identifies the year-end dates by (calendar) year:
SELECT Year(Dates) AS CalendarYear, Max(Dates) AS YearEndDate
FROM NSE20
GROUP BY Year(Dates)
That will produce
CalendarYear YearEndDate
------------ -----------
2010 2010-12-31
2011 2011-12-30
2012 2012-12-31
Then I'd create another saved query named [NSE20_year_end_balances] to extract the closing balances for each year:
SELECT NSE20_year_ends.CalendarYear, NSE20.PXLast
FROM
NSE20
INNER JOIN
NSE20_year_ends
ON NSE20.Dates = NSE20_year_ends.YearEndDate
That will give us
CalendarYear PXLast
------------ ------
2010 130
2011 125
2012 129
Now we can do a self-join on that query to calculate the percentage change
SELECT
y1.CalendarYear,
(y1.PXLast - y0.PXLast) / y0.PXLast * 100 AS PctChange
FROM
NSE20_year_end_balances y1
INNER JOIN
NSE20_year_end_balances y0
ON y0.CalendarYear = y1.CalendarYear - 1
resulting in
CalendarYear PctChange
------------ -----------------
2011 -3.84615384615385
2012 3.2
