The CData JDBC Driver for SAP HANA XSA 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 t.JobId, t.Id, j.UserAssigned FROM Jobs j INNER JOIN JobTasks t ON j.Id = t.JobId

Left Join

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

 SELECT j.Id, t.Id AS TaskID, j.UserAssigned FROM Jobs j LEFT JOIN JobTasks t ON j.Id = t.JobId
