The EVALUATE statement in DAX Studio

Introduction

EVALUATE is a key statement in DAX used in the context of queries to define which table (or tabular result) should be returned. Essentially, it tells the DAX engine "I want to see the results in table format for this particular expression."

How to use the EVALUATE statement:

As we can see, the EVALUATE statement in DAX Studio returns a table. This means that a table must be passed, as seen in the example.

Conclusion:

Another common use case is with table-type functions, such as the VALUES function.

In the case that we want to see the result of a scalar-type function, meaning it returns a single result, we will use table-type constructors { } as we can see in the example.

EVALUATE is essential for building queries in DAX Studio. It allows the user to define what data they want to see and in what format, offering the flexibility to combine, filter, and transform data in a variety of ways. It's a powerful tool in the hands of someone looking to explore or analyze data in a Microsoft tabular model.
