我想为用户分配查看 EMP 表的权限

Question

错误说表不存在。我的问题是为什么我会收到错误？

SQL> GRANT SELECT, INSERT, UPDATE, DELETE ON system.emp to chap7;
GRANT SELECT, INSERT, UPDATE, DELETE ON system.emp to chap7
                                           *
ERROR at line 1:
ORA-00942: table or view does not exist

该表确实存在，

 SQL> select ename from emp;

 ENAME
 ----------
 KING
 BLAKE
 CLARK
 JONES
 MARTIN
 ALLEN
 TURNER
 JAMES
 WARD
 FORD
 SMITH

 ENAME
 ----------
 SCOTT
 ADAMS
 MILLER
 Stuttle

Answer 1

也许 EMP 表不属于 SYSTEM？ Do：

SELECT owner FROM all_tables WHERE table_name = 'EMP'

另外，您以什么用户身份执行 GRANT 和 SELECT 操作？
