INNER JOIN b ON a.key = b.key You can write equivalent syntaxes in DAX by using the NATURALLEFTOUTERJOIN and NATURALINNERJOIN functions, respectively, if there is a relationship connecting the two tables involved. For example, this query returns all the rows in Sales that have corresponding...
Overview One of the primary requirements of a query is to join different tables to create the desired resultset. There are a couple of ways to achieve this in DAX by using the Add Columns function as well as the Summarize function. In this chapter, we will learn how to use both of the...

Calculated tables in Analysis Services. Row-level security With row-level security, a DAX formula must evaluate to a Boolean TRUE/FALSE condition, defining which rows can be returned by the results of a query by members of a particular role. For example, for members of the Sales role, the...
referential integrity be enforced between two tables in order to define a valid relationship. Instead, a blank row is created on the “one” end of each one-to-many relationship and is used to handle all non-matching rows from the related table. It effectively behaves as a SQL outer join...
