Aggregate Functions | Backendless Database Training Course (pt. 43)
In this video, we will talk about aggregate functions available in Backendless. We will go over the four different functions that we support: count, min, max, and avg. Being able to calculate numbers quickly and efficiently and have the database do it for you is what makes databases quite powerful. We will demonstrate how aggregate functions work in Backendless by going over various examples. We will be using the schema for a database that you should already have installed if you're following this course. In the first example, we will review how to get an average price for products in the widget category. The second example will be getting an average order amount for products in the widget category. In both examples, we will demonstrate how to use aggregate functions in Backendless, and we will show how the requests should be sent to the table to retrieve the results we need.
