The Adapter 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.CarrierName, o.JobTitle, o.FirstName, o.PhoneNumber FROM Carriers c INNER JOIN Carriercontacts o ON c.CarrierId = o.CarriersCarrierId

Left Join

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

 SELECT c.CarrierName, o.JobTitle, o.FirstName, o.PhoneNumber FROM Carriers c LEFT JOIN Carriercontacts o ON c.CarrierId = o.CarriersCarrierId
