（ ）CREATE VIEW 只是把视图的定义存入数据字典，并不执行其中的SELECT语句
举一反三
- 下列【视图】创建语句错误的是？ A: CREATE VIEW 视图名 AS SELECT语句; B: CREATE OR REPLACE VIEW 视图名 AS SELECT语句; C: CREATE VIEW 视图名 SELECT语句 WITH CHECK OPTION; D: CREATE VIEW 视图名 AS SELECT语句 WITH CHECK OPTION;
- 请选择正确的视图创建语句() A: create view视图名as select语句 B: create show视图名as select语句 C: create view视图名as insert语句 D: create show视图名as insert语句
- 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
- 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;
- 创建视图的语法格式是:Create view 视图名称( ) select 查询语句
