I'm trying to use an aggregate case to create a Pivot table. However, for my created column to represent row number, it shows an Error

Code: 1056. Can't group on 'rn'.

Meanwhile, if I do the same job manually (by adding the id column to my table it works fine).

Here is code:

I'm trying to reshape my dataframe, in which I want the Person to the be index, however how do I make it so the index is unique? I don't know want duplicates in my Index.

I have two ejs forms that when hit, make an HTTP post request to my /api/users/makePicks/:id route. This route hits my controller which updates the Users model in my mongodb with the NFL picks they submitted in the EJS form.

I need this route to create the picks object for each route if they do not exist for that particular week, and if they do exist it needs to update the picks that are already there. The picks are being stored in my User model in an array, this array contains objects for each weeks picks. Currently the code, with much help from Mohammed, is successfully pushing code to to array. But i cannot seem to figure out how to update the picks if an object with a key of that week exists.

My validation is finally working properly. What I mean is we are running a for loop on the picks array, it will console.log true if there is already a matching picks object with for that weeks picks, if the object with a first key value with the current weeks form doesn't exist, it will console.log false and push the new picks to the array.

The only part that isn't working is the if statement nested within my for loop, it is not updating the object if it already exists in the picks.array. But as I said, the validation is working correctly. I suspect the line of code

I have the followings 3 dummy documents. I wish to find all documents where the end_terminal is "LGA" AND the value is equal or above 0.50 for the same end_terminal.

for this I do:

How do I change my clickable square image into a circular image on Flutter?

This is the constructor (it's fullpropped, but here I only show 1st line):

I've got this code and i want to limit the primary y-axis between 0 and 3500 (the y-axis on the left).

The second y-axis i want a limit between 30 and 65 (the y-axis on the right).

The two y-axis need to be independent of each other.

I created a maven project with IntelliJ IDEA, following a tutorial.

The tiny project in JDK11 is to demo (for myself) how com.google.code.gson serializes an object to a json string.

This project's POM is:

I have a dataframe, the head of which looks like this:
