I am trying to find a formula which can help me find the average of the results for the 4 criteria's used with ID; Company Name; Code & Activity by using isnumber search options: Example: Table with the details coming from the report extracted and format will not be same always:

Assumptions:

User is required to enter/select a certain combination of the four 'criteria'
Average is taken over scores for which all four of these criteria are satisfied (if fewer, score does not 'qualify' to be 'averaged')

Approach

Each of your criteria can be evaluated in the form of a matrix of 1s & 0s corresponding to 'criteria satisfied' and 'not satisfied' resp. Screenshot refers:

You can use .groupby.agg, to compute the rolling mean for only the recent data you can take head(3) and compute mean of it.

QUESTION

Mapping All Terminal IDs to Previous IDs

Asked 2021-Apr-15 at 03:59

I have a table in SQL Server that contains a list of all ID migrations overtime. An individual's ID can change overtime, and this table helps us understand when the change occurs, and what the ID changes from/to. What I'd ultimately like is a way to list all of the previous IDs for the most recent ID (which I'm referring to as the terminal ID). I'm assuming this will require some sort of CTE, but my brain is in a bit of a fog as to how I should set this up.

I'm not sure what you're up to.

You can use a jinja2 filter to convert the data into a JSON compliant string. It is also important to pay attention to the quotation marks.

ANSWER

Answered 2020-Dec-18 at 23:41

Sadly, the answer to this question is that there is no way in DAX to refer to the rows position relative to the other rows in the table. The only option is to use some column value for sorting purpose.

What we could do with the existing two columns table is to get the MAX or MIN Firstname per each Email. So we can write a calculated table like follows, where T is the input table and T Unique is the generated table.

QUESTION

Can my App know which QR code was used to download it

Asked 2020-Nov-20 at 13:20

I am building an Android application (SDK 24+), using Google Cloud services like Firebase as my back-end.

What I would like to achieve is, having multiple, unique QR codes all of which will lead to my app being downloaded. Also, at the same time, I want my app to know from which QR it was downloaded.
In effect, besides using the different QRs for downloading my app, I also want them to serve as a unique ID inside my app.

Example:
Let's say we have 5 different QRs: QR-a, QR-b, QR-c, QR-d, QR-e. I want all 5 of them to lead to my app being downloaded and, once it has been downloaded, I want my app to be aware of the QR used to download it, be it QR-a, QR-b, or whichever else.

My own thoughts:
From my understanding the first part (different QRs downloading the same app) should be doable, but is the second one (the app being aware of which QR it was downloaded from) even feasible?
I know services like Google Analytics provide a lot of detail on the device/user that used a QR. Perhaps, after downloading the app using QR, the app could query Google Analytics about which QR the user used to download it.

It's the first time I'm working with QRs, so my understanding on them may be fundamentally flawed.
Any thoughts or ideas on how to approach this problem will be appreciated.

If all your links point to the Google Play Store, then this is doable by using the Google Play Store Install Referrer API.

Passing data to Google Play Store

Your QR codes need to point the user the store page of your app. Additionally, they need to pass more data in by using the referrer URL parameter.

One of your links could look like this:

https://play.google.com/store/apps/details?id=com.example.okariotisapp&referrer=qrdata%3DQR-a

This URL consists of the following parts:

Base URL for the store page of an app on the Google Play Store:
- https://play.google.com/store/apps/details?id=
Your application ID:
- com.example.okariotisapp
referrer URL parameter:
- &referrer=
Your freely choosable key-value data. In this case with qrdata as a key and QR-a as a value (note, that %3D is the HTML URL enconding for =):
- qrdata%3DQR-a

Access referrer data in the app

The easiest way to access the referrer data is using the Play Install Referrer Library.

Add the dependency to the library and establish a connection to the Play Store once your app has been installed and started. Inside the onInstallReferrerSetupFinished callback, access the referrer data if the responseCode for the connection is equal to InstallReferrerResponse.OK
