下列在student表上创建view_stu视图的语句中，正确的是
A. CREATE VIEW view_stu IS SELECT * FROM student;
B. CREATE VIEW view_stu AS SELECT * FROM student;
CREATE VIEW view_stu SELECT * FROM student;
D. CREATE VIEW SELECT * FROM student AS view_stu;
视图定义如下：CREATE VIEW view_stu2(math,chin,sum)AS SELECT math,chinese,math+chinese FROM student;下面选项中，能够正确使用视图的语句是
A. SELECT * FROM view_stu2;
B. CALL view_stu2(math,chin,sum);
C. SELECT * FROM view_stu2(math,chin,sum);
D. SELECT view_stu2;
