The CData Power BI Connector for Oracle Service Cloud 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 c.DisplayName, o.Address, o.AddressTypeId, o.Certificate FROM Accounts c INNER JOIN AccountsEmails o ON c.Id = o.AccountsId

Left Join

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

 SELECT c.DisplayName, o.Address, o.AddressTypeId, o.Certificate FROM Accounts c LEFT JOIN AccountsEmails o ON c.Id = o.AccountsId
