使角色 R1 拥有 Student 表的 SELECT、UPDATE、INSERT 权限的语句是
A: GRANT SELECT, UPDATE, INSERT ON TABLE Student to R1
B: REVOKE SELECT, UPDATE, INSERT ON TABLE Student to R1
C: AUDIT SELECT, UPDATE, INSERT ON TABLE Student to R1
D: ROLE SELECT, UPDATE, INSERT ON TABLE Student to R1
A: GRANT SELECT, UPDATE, INSERT ON TABLE Student to R1
B: REVOKE SELECT, UPDATE, INSERT ON TABLE Student to R1
C: AUDIT SELECT, UPDATE, INSERT ON TABLE Student to R1
D: ROLE SELECT, UPDATE, INSERT ON TABLE Student to R1
举一反三

- 将查询和修改Student表的权限授给用户U4的SQL语句是(<br/>)。 A: GRANT<br/>SELECT, UPDATE ON TABLE Student TO U4 B: REVOKE<br/>SELECT, UPDATE ON TABLE Student FROM U4 C: GRANT<br/>SELECT ON TABLE Student TO U4 D: REVOKE<br/>UPDATE ON TABLE Student FROM U4
- 使角色R1减少SELECT权限的语句是( )。 A: REVOKE<br/>SELECT ON TABLE Student FROM R1
- 将查询Student表和修改学生学号的权限授给用户U4。实现此功能的SQL语句是(<br/>)。 A: GRANT UPDATE(Sno),SELECT<br/>ON TABLE Student TO U4 ; B: GRANT UPDATE,SELECT<br/>ON TABLE Student TO U4 ; C: GRANT SELECT ON TABLE<br/>Student TO U4 ; D: GRANT UPDATE ON TABLE<br/>Student TO U4 ;
- 给xiaowang的用户分配对数据库course 中的student表的查询、更新和插入数据权限的语句是_______。 A: grant select,update,insert on course.student for ‘xiaowang@localhost’; B: grant select,update,insert on course.student to ‘xiaowang@localhost’; C: grant ‘xiaowang@localhost’ to select,update,insert for course.student; D: grant ‘xiaowang@localhost’ to course.student on select,update,insert;
