B.UPDATE stu SET dept="maths" WHERE age>=20
C.INSERT INTO stu VALUES("2004001","John",30,"cs")

职员关系模式为E(Eno,Ename,Dept,Eage,Eaddr)。其中,Eno表示职员号,Ename表示职员名,Dept表示职员所在部门,Eage表示年龄,Eaddr表示职员的家庭住址。建立“开发部”(DS表示开发部)职员的视图DS_E如下,要求进行修改、插入操作时保证该视图只有开发部的职员。
CREATE VIEW DS_E
AS SELECT Eno,Ename,Dept,Eage,Eaddr
FROM E
WHERE(47);
如下SQL语句可以查询开发部姓“王”职员的姓名和家庭住址。
Select Ename, Eaddr
From DS_E
Where(48);
A.Dept=DS
B.Dept=DS WITH CHECK OPTION
C.Dept='DS'
D.Dept='DS' WITH CHECK OPTION
