The CData Power BI Connector for Adobe Commerce supports standard SQL joins like the following examples.

Inner Join

An inner join selects only rows from both tables that match the join condition:

SELECT Customers.Email, Orders.CreatedAt FROM Customers, Orders WHERE Customers.EntityId=Orders.CustomerId

Left Join

A left join selects all rows in the FROM table and only matching rows in the JOIN table:

SELECT Customers.Email, Orders.CreatedAt FROM Customers LEFT OUTER JOIN Orders ON Customers.EntityId=Orders.CustomerId
