Question
Which is a valid trigger.
BEFORE TRIGGER
BEFORE UPDATE TRIGGER
AFTER TRIGGER
- None of the mentioned
Solution
The valid triggers are:
- BEFORE TRIGGER
- AFTER TRIGGER
The term "BEFORE UPDATE TRIGGER" is not typically used as a standalone term in SQL. Instead, you might see something like "BEFORE UPDATE" as part of a trigger definition, specifying that the trigger should run before an update operation is performed.
"None of the mentioned" is not a valid trigger. It's a phrase often used in multiple choice questions to indicate that none of the previously listed options are correct. In this case, it's not applicable because the first two options are valid triggers.
