問題文
A statement inside a session for which the waiting behavior has been turned on has been waiting for some time, and nobody is able to make room for it today. Which statement about the ways that wait comes to an end is correct?
選択肢
- A time limit is tied to the wait and the session is closed once that limit has passed, and no procedure is supplied for ending the wait sooner, so the account has to open a session once more after the close.
- A time limit is tied to the wait and the statement wakes and carries on without room once that limit has passed, and a supplied procedure ends the session sooner when either an administrator or the account that issued it happens to call that procedure upon it.
- A time limit is tied to the wait and the statement wakes and hands the error back once that limit has passed, and a supplied procedure forces the same error sooner when either an administrator or the account that issued it calls that procedure.
- No time limit is tied to the wait so the statement stays where it is until room has been made for it, and a supplied procedure forces the error sooner when an administrator alone calls that procedure upon the statement.
