Writing Queries in DAX Studio

The most straightforward DAX query is in the form of EVALUATE.

The table expression can be as simple as the name of a table like in our case, it can be EVALUATE (Customers) or it could be a DAX function that returns a table such as FILTER or SUMMARIZECOLUMNS.

EVALUATE statement:

EVALUATE is a DAX statement containing a table expression and is needed to execute a query. A query can also have multiple EVALUATE statements, but the key point here is that it requires a keyword.

Query Builder:

If you are learning DAX, or if you want to see how a query is created, Query Builder is the best option in DAX Studio. It provides a graphical user interface that makes it easier to build queries. Let’s use query builder to get total sales amount by product category.
