The CData Power BI Connector for Snapchat Ads 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 AdSquads.Name, Ads.DeliveryStatus FROM AdSquads, Ads WHERE AdSquads.Id=Ads.AdSquadId

Left Join

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

SELECT AdSquads.Name, Ads.DeliveryStatus FROM AdSquads LEFT OUTER JOIN Ads ON AdSquads.Id=Ads.AdSquadId
