Question

CREATE TRIGGER ATTENDANCE_INSERTION_TRIGGER
ON course_enrollment
AFTER INSERT
AS
BEGIN

--insert **what just was inserted in course_enrollment** into course_schedule_attendance

END
GO

How do I refer to what just was inserted in course_enrollment ?

Answer 1

try this:

CREATE TRIGGER ATTENDANCE_INSERTION_TRIGGER 
ON course_enrollment 
AFTER INSERT 
AS 
BEGIN

  --insert **what just was inserted in course_enrollment** into
  -- course_schedule_attendance  
  INSERT course_schedule_attendance  
      (course_id, student_id)
    SELECT
      course_id, student_id --you could use: INSERTED.course, INSERTED.student_id
      FROM INSERTED
END 
GO 

you could also do this in a single INSERT, without the trigger:

--insert a single row in both tables at one time
INSERT course_enrollment 
      (course_id, student_id)
      OUTPUT course_id, student_id INTO course_schedule_attendance  
   VALUES (@xyz, @abc)

--or insert a set of rows into both at one time
INSERT course_enrollment 
      (course_id, student_id)
      OUTPUT course_id, student_id INTO course_schedule_attendance  
   SELECT
       xyz, abc
       FROM ...
