SQL Server - 對於插入觸發器

Question

對於'插入'觸發器，是否在觸發時插入表中的行？

CREATE Trigger check_availability on Room 
     For Insert, Update 

謝謝！

Answer 1

是的。

CREATE TRIGGER

FOR | AFTER 

    AFTER specifies that the DML trigger is fired only when all operations specified in the triggering SQL statement have executed successfully. All referential cascade actions and constraint checks also must succeed before this trigger fires. 

    AFTER is the default when FOR is the only keyword specified. 

    AFTER triggers cannot be defined on views.
