#MDX

3

Multidimensional Expressions (MDX) is a query language for online analytical processing (OLAP) using a database management system. Much like SQL, it is a query language for OLAP cubes.

How are we doing THIS year versus the same period LAST year?
This is a common need in Business Intelligence. In fact, many design specifications for reports make use of a comparison between a selected period (year, quarter, etc) up to a certain date (for example November 15th, 2016) and a summary of the same information for the previous year (i.e. up to November 15th, 2015).
This post shows how to implement this in DeepSee.

Hi-

I am trying to figure out how to compare two dimension values in a MDX query such that records where two dimension values are the same will be filtered out.

To test this, I have modified the HoleFoods cube in SAMPLES namespace to have a new dimension called RandomRegion

I want to create a MDX query where the [Outlet].[H1].[Region] value is not equal to the [RandomRegion].[H1].[RandomRegion] value.

Here's the query I need to add the filter to:

Accessing Deepsee plugin in MDX

Dear All,

From my web page, i am passing filter values to mdx query.

when mdx executes, i am getting Error #5001: Invalid member expression: empty name(2).

when i try the same in samples namespace (patient cube). I got the same error.

Below is my sample MDX from patients cube.

SELECT 
NON EMPTY %KPI("PluginDemo","HighScoreCount",,"%CONTEXT") 
ON 1 
FROM [PATIENTS] 
%FILTER %OR([HOMED].[H1].[ZIP].&[32000])

Result: 0 This works fine.

I currently have an MDX query/calculated measure as per the below:


[DaysOnListRange].[H1].[DaysOnListRange].&[Days 91 - 180]+ [DaysOnListRange].[H1].[DaysOnListRange].&[Days 181 - 365]+
[DaysOnListRange].[H1].[DaysOnListRange].&[Days 365+]

however it currently doesn't sum when there is a blank in the data.
How can I amend this query to include empty cells/only sum cells with data?

I've tried using nonempty but it doesn't appear to work in this context

In DeepSee, having a customer account cube. The cube includes a time dimension AccountCreationDate.

How do you create a calculated measure to get the total number of accounts from the beginning to a certain date in abscissa ?

I tried many things including this:
AGGREGATE(%TIMERANGE([AccountCreationDate].[H1].[MonthYear].&[190001],[AccountCreationDate].[H1].[MonthYear].CURRENTMEMBER) ,[Measures].[%Count])

But I don't get the right result because the date in abscissa creates a filter on the first date.

Hi all,

I have a dashboard which shows the growth of the months compared with the month from the last year.

The way I found to develop that, it was with a kpi. So, I overrode the %OnLoadKPI method with two mdx:

SELECT NON EMPTY [DataD].[H1].[MothYear].Members ON ROWS, [Measures].[CountVisits] ON COLUMNS FROM SubjectAtendimento %FILTER [DataD].[H1].[Year].&[2016]

SELECT NON EMPTY [DataD].[H1].[MonthYear].Members ON ROWS, [Measures].[CountVisits] ON COLUMNS FROM SubjectAtendimento %FILTER [DataD].[H1].[Year].&[2015]

The DeepSee Shell Best Practices Series - Example of using the MDX subquery flag in the DeepSee Shell

We have different flags for DeepSee advisors to look into the execution details and the methods DeepSee is using to do calculations.

flag [flagname] [on|off] – Turn a diagnostic on or off.

flag cmbr on|off – Show current member processing.

flag compound on|off – Show rewrite of compound queries.

The DeepSee Shell best Practices Series - Execute an MDX query in the DeepSee Shell with/without results cache

This cache is different from cache reset. Cache reset clears everything in the namespace but “cache off” only clears the cache in ^DeepSee.Cache.Results and ^DeepSee.Cache.Axis global node for the corresponding cube. The difference is quite smaller in the case as below, but in some cases it can be a big difference.
