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 w.WorkerID, w.WorkerOriginalHireDate, a.ItemID, a.ActualStartDate FROM Workers w INNER JOIN WorkersWorkAssignments a ON w.AssociateOID = a.AssociateOID

Left Join

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

SELECT w.WorkerID, w.WorkerOriginalHireDate, a.ItemID, a.ActualStartDate FROM Workers w LEFT JOIN WorkersWorkAssignments a ON w.AssociateOID = a.AssociateOID
