am currently building a ssas cube. I need the default to bring back 2 periods in time. Last month and the month prior to that.
For last month I am using
tail(nonempty([service date].[quarter no - month no].members))
which works perfectly, however it is the previous month to this that I am struggling with.
Can anyone help please? Thankyou.
update:
I am using this mdx as a calculation inside SSAS to then use as a filter for the dataset inside ssrs.
My results are currently:
Contract Name Question TblFct Month Year
------------- ------- ------ ----- ---
New Homes How Many 600 Dec 2014
This is the number for the last month that has data in, i.e. December 2014. I am aiming to have another dataset that is automatically filtered by the same criteria but instead of the last non empty month, I am looking for the month preceeding that. I had looked at the lag function but haven't been able to make it stick for some reason.
My comparison dataset should yield:
Contract Name Question TblFct Month Year
------------- ------- ------ ----- ---
New Homes How Many 450 Nov 2014
The quickest solution is to use HEAD function before TAIL, but this is acceptable only in case of non-empty value in this period:
head(tail(nonempty([service date].[quarter no - month no].members),2),1)
But actually even your first solution for the last month may fail if you give users an opportunity to filter data by some dimensions in further SSRS reports with this kind of filters. As for my previous experience, it's better to set up month's parameter 'Last' as additional column/property and after that: as additional dimension hierarchy of current [service date] dimension.
In case of fully-dynamic behavior (when last month differs from report to report), please specify what is acceptable if prev. month is empty:
we need to show empty/zero value
we need to take previous non-empty member (this way it's implemented above)

In our date dimension, there are Month and Year attributes. Month attribute has set int month_year as key, to avoid duplicate problem, and Month attribute has name like January, February...
Now there is problem, if user drags Year and Month to filter, and would define one year, say 2017, he expect to see Month Attribute in filter only shows 12 month names in 2017. However, Month Attributes shows month names for all years, the names repeating many times.
There is already calendar hierarchy built in this dimension. But the user wants to define filter outside of hierarchy. How to build such Month Attribute in cube? Does some one have any idea about it? Thanks in advance!
The problem has been solved. Just add a new column in date table, say Month_in_current_Year, has the same content as Month column. Add this new column to date dimension as a new attribute. This new attribute works for my purpose. It shows only 12 elements as months in one year. And it slices correct value while setting it to filter. What magic is the cube!
I've got a number of rows and I want to calculate the difference per date.
So say I have the following:
[Date] [Transaction Number] [Value]
1 Jan 16 1 1000
2 Jan 16 1 980
I then want a fact that for every row will compare the value with the measure from the previous date.
So If I have a measure on SUM(Value) for the current date, I basically want SUM(CurrentDate) - SUM(PreviousDate) to see the movement.
A couple of things to note:
There will actually be a couple of comparisons: previous date, previous month end, previous year end.
I want this as a calculated measure not column so that I do not need to filter on the transaction number in the previous period.
What I've tried but it just comes up empty:
Previous Value :=CALCULATE(SUM(Table[Value])) - CALCULATE(SUM(Table[Value]), FILTER(Table, Table[Date] = PreviousDay(Table[Date])))
Unfortunately I cannot tell why your measure didn't work, but following should:
Previous Value := CALCULATE(SUM(Table[Value]) - CALCULATE(SUM(Table[Value]), PREVIOUSDAY(Table[date])))
I have an SQL query I need to run once a month.
The data set the query produces always has to be from the 11th of the month before to the 10th of the current month.
I now manualy run the query in the fews days after the 11th day of the month manually adjusting the date range in my where statement:
for example...
Where Column A is greater than 10/10/2015 and less than 12/11/15
I was hoping there would be a statement I could add to my query to automatically find the 11th day of the last month and the 10th of the current month. This way I could schedule the query and automatically email the results.
You should be able to use the following within your query: -
CONVERT(date,FORMAT(GETDATE(),'yyyy-MM')+'-10')
(for the 10th of this month)
and
CONVERT(date,FORMAT(DATEADD(m,-1,GETDATE()),'yyyy-MM')+'-11')
(for the 11th of last month).
Try to look out the MONTH() function in your working DBMS. In MySQL and MSSQL it returns a number (1 been january) corresponding to the current month that your system is (you may check if it's date is updated).
With this function you can subtract 1 to get the last month, having to do some logic when the current one is January, hence 1. Since now you should get 12 (december) intead of 0 (an error).
Cheers, mate!
I want to summarize sql query result week wise and month wise at the same time in a grid view. Is this even possible or I am just dreaming?
Requirement:
Show last one month data and next two month's data week wise in the grid.
Example-
If the current month is September then I want to show data from 1st August to 31st October categorized in weeks.
Show the data after the next month of current month in month wise view in the same grid.
Example-
data for month November and December will be shown categorized in month not in weeks.
grid or result should look something like below -
Please suggest something to achieve this
If you want a maintainable solution, use two independent queries, one for weekly aggregation other for monthly. Depending on the input run corresponding query.
I think you must work with group by or group by ... cube
SELECT x , y from <tabel> GROUP BY date_feld( to_char( 'MM' ))
but i don't now your DBMS so i can't give you a exact example for the date handling.
This is regarding calculating the sum for a set of values starting from the date a measure has entries till the current date.
So far what I could find was the YTD function. This limits the aggregation capability till the current date beginning from the first day of the year. But what my requirement is to start the calculation from the first value, this could be in the last year or may be two years before.
Eg:
Date-----------Value
11/9/2010-----2000
2/10/2011-----500
8/5/2011------1000
With YTD the value is: 1500
What I need is: 3500
I really appreciate any help on this.
Something like:
SUM([Date].[Day].AllMembers, [Measures].[Value])
OR
SUM(OpeningPeriod([Date].[Day]):ClosingPeriod([Date].[Day]), [Measures].[Value]),
where [Date].[Day] - it's a level DAY of your dimension;
[Measures].[Value] - your measure.
