Question

If a run an INSERT INTO statement that triggers an INSERT AFTER trigger. What table/row(s) does the inserted and deleted objects represent in the trigger? For example,

INSERT INTO Person.person (personID, name) VALUES (1, 'robert')

CREATE TRIGGER myTrigger  
ON Person.person  
AFTER INSERT AS  
BEGIN  
 insert into Person.PersonMovies (personID, movieID)  
 select inserted.personID  from inserted   _--i know the code is incomplete, but i'm curious only about the inserted part._  
END  

I’m confused as to what records are held by the inserted table. Would it be the records in the insert statement that triggered the trigger or the Person.PersonMovies table?

Answer 1

Yes, the inserted/deleted tables gives your trigger code access to the records changed by the statement that caused (triggered) the trigger. Also remember that your statements could have effected multiple rows, so your deleted or inserted tables could have multiple records.
