A team wants somebody told when a query reaches a row that a fine-grained policy is watching. Which statement about the way that is arranged is correct?
選択肢
- A rule can be named that the trail itself obeys, and the trail sends the message once it has written the record, so the message follows the record rather than the condition.
- A stored program can be named in the policy and the database calls it once the condition has been met, so the message goes out without anybody reading the trail.
- A schedule can be named in the policy and the database looks back through the records at the hour that the schedule names, so the message goes out at the end of each period of the day rather than at once.
- A stored program can be named in the policy and the database calls it before the condition has been worked out, so the message goes out for every statement that reaches the table rather than for the rows that meet it.
