The CData Power BI Connector for Pinterest 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 b.Name, b.Description, s.Name FROM Boards b INNER JOIN BoardSections s ON b.Id = s.BoardId

Left Join

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

 SELECT b.Name, b.Description, s.Name FROM Boards b LEFT JOIN BoardSections s ON b.Id = s.BoardId
