下面定义视图的SQL语句，哪一个是错误的？（ ）
A: create view VIEW1 as select id,name,sex from users
B: create view VIEW2 as select count(*) as studentTotal,classname from student
C: create view VIEW3 as select name,price from
D: create view VIEW4 as select logdate,price,1.1*parice as ‘涨价’ from shop
A: create view VIEW1 as select id,name,sex from users
B: create view VIEW2 as select count(*) as studentTotal,classname from student
C: create view VIEW3 as select name,price from
D: create view VIEW4 as select logdate,price,1.1*parice as ‘涨价’ from shop
举一反三
- 在student表上创建view_stu视图,正确的语句是( )。 A: CREATE VIEW view_stu IS SELECT * FROM student; B: CREATE VIEW view_stu AS SELECT * FROM student; C: CREATE VIEW view_stu SELECT * FROM student; D: CREATE VIEW SELECT * FROM student AS view_stu;
- 下列哪条语句可以创建视图( )。 A: create view v_student as select * from student; B: alter view v_student as select * from student; C: drop view v_student as select * from student; D: sp_help view v_student as select * from student;
- 建立信息系统学生的视图是（） A: CREATE VIEW is_student AS SELECT sno,sname,sage FROM student WHERE sdpt='is'; B: CREATE VIEW is_student SELECT sno,sname,sageFROM WHERE sdpt='is'; C: CREATE VIEW is_student AS select sno,sname,sage FROM WHERE sdpt='is' D: CREATE VIEW is_student AS SELECT sno,sname,sage WHERE sdpt='is';

- 以下是修改视图的语句是 A: create or replace view st1 as select* from student; B: alter view st1 as select name from student join class on student.cid=class.id; C: alter table st1 modify class int(3); D: create or replace table st1 as select* from student;
