                '; ' + Title
            FROM
            (
                SELECT DISTINCT
                    ces.CourseEventKey,
                    f.Title
                FROM
                    CourseEventSchedule ces
                INNER JOIN Facility f 
                    ON f.FacilityKey = ces.FacilityKey

                        FROM @CourseEvents
