arrayquery | ArrayQuery is a library to query arrays

I new in node.js and have some problems with sequelize-cli. I have sequelize model and while I run the project, i get error in my index.js:

I have been wondering how can I get less than 50 rows of data with azure. Reason being I only need the top 5 rows of data from the database and display onto the android UI.

However, when I am experimenting .top(), the lowest I can go is 40. Anything lower than that, the return JsonArrayQuery will not be regarded as an Array.

I'm trying to find a simple solution for first-n-per-group.

I have a table of data, first column dates and rest data. I want to group based around the date, as multiple entries per date are allowed. For the second column some numbers, but want the FIRST record.

Currently the aggregate function I could possibly use is MIN() but that will return the lowest value and not the first.

I defined the web parameter as const map = new Map(); and I put values inside with map.set(metaById[i].id, metadatoForm[i]);

On the Angular side (trough browser console) I can see the item is passed correctly, but on the Java side I receive a strange object, it hasn't the correct size and it is empty (it has also empty keyset)

I am preparing statement from json array of php and adding it to simple array list.

Am getting logcat error as :
