JOIN Queries
The Workday 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 Human_Resources.Workers.Worker_Reference_WID, Human_Resources.Workers.Legal_Name_Last_Name, Human_Resources.Workers_Address_Data.Municipality FROM Human_Resources.Workers INNER JOIN Human_Resources.Workers_Address_Data ON Human_Resources.Workers.Worker_Reference_WID = Human_Resources.Workers_Address_Data.Workers_Worker_Reference_WID
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT Human_Resources.Workers.Worker_Reference_WID, Human_Resources.Workers.Legal_Name_Last_Name, Human_Resources.Workers_Address_Data.Municipality FROM Human_Resources.Workers LEFT JOIN Human_Resources.Workers_Address_Data ON Human_Resources.Workers.Worker_Reference_WID = Human_Resources.Workers_Address_Data.Workers_Worker_Reference_WID
