The Bullhorn CRM 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.CandidateName, o.Certification, o.GraduationDate, o.Comments FROM Candidate c INNER JOIN CandidateEducation o ON c.Id = o.CandidateId

Left Join

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

 SELECT c.Subject, o.AttendeeId FROM Appointment c LEFT JOIN AppointmentAttendee o ON c.Id = o.AppointmentId
