[Fill in the blank question 1] share the computer grade level two questions, the simulated questions are for reference

I hope you get good results in the test, and I hope you can pass the test, and then report to the next three levels. I don't know if I can post it or want to share it:

Use the following SQL statement to create a stored procedure in the database XK to implement a course number course_id in the given table course, and you can specify a new classroom for the course corresponding to the course number in the table course.

USE XK :
DELIMITERS $$
CREATE _______ SP_UPDATE_ROOM(in cid int,in rno char(20))
BEGIN
update course set room = rno where course_id = ______;
end _______

I forgot to remember the subject of a trigger above, but I have the code. It
seems to create a trigger to automatically delete the student's course selection information.

USE XK ;
CREATE ______ TRIGGER_DELETE_STUDENT_BEGIN____DELETE
ON ____ FOR EACH ROW
DELETE FROM ______ WHERE STU_NO=OLD.STU_ID;
