What’s important to note is that Hibernate doesn’t ever refer to it as
So, armed with this knowledge, let’s jump into the lesson!
Grouping Data with Hibernate
In our examples, I’m going to show you how to create a query with hibernate that will group your data in some manner.
When we build our query, we will be focusing on using Hibernate’s
First, let’s start off with an example that we will build on.
