【正确答案】①SELECT Sname，Sage
FROM Student
WHERE Sage＜ANY(SELECT Sage
FROM Student
WHERE Sdept='CS')
AND Sdept＜＞'CS'
②CREATE VIEW IS_S1(Sno，Sname，Grade) AS
SELECT Student.Sno，Sname，Grade
FROM Student，SC
WHERE Sdept='IS' AND
Student.Sno=SC.Sno AND
SC.Cno='1'；
③CREATE TRIGGER Print_f
AFTER INSERT ON Student
FOR EACH ROW
AS BEGIN
IF(new.Grade＜60)THEN
PRINT'不及格'
END IF
END；

【答案解析】[解析] 创建视图用CTREATE VIEW，而创建触发器是用CREATE TRIGGER，触发器分为行级触发器和语句级触发器，FOR EACH ROW是行级触发器。
