给普通用户赋予对v$视图的查询权限，结果报 ORA-02030 错误
ORA-02030: 只能从固定的表/视图查询(ORA-02030: can only select from fixed tables/views)

问题背景:
在一个dba用户下的存储过程中需要使用v$的视图(v$client_stats)
使用命令行测试:
SQL> variable total number;
SQL> begin
2 select count(1) into :total from v$client_stats;
3 dbms_output.put_line('total = '|| :total);
4 end;
5 /
PL/SQL procedure successfully completed
total
---------
0
这样并没有问题，于是编辑成过程执行
使用过程
SQL> create or replace procedure p_test
2 authid current_user
3 as
4 v_all number := 9999;
5 begin
6 select count(1)
7 into v_all from v$client_stats;
8
9 dbms_output.put_line('v_all =' ||v_all );
10 end;
11 /
Warning: Procedure created with compilation errors
具体错位信息
Compilation errors for PROCEDURE ZHANGBIN.P_TEST
Error: PL/SQL: ORA-00942: 表或视图不存在
Line: 9
Text: FROM v$client_stats;
Error: PL/SQL: SQL Statement ignored
Line: 7
Text: SELECT COUNT(1)
此时需要给用户赋查询权限(于是产生了ORA-02030错误)
SQL> show user;
User is "SYS"
SQL> grant select on v$client_stats to zhangbin;
grant select on v$client_stats to zhangbin
ORA-02030: 只能从固定的表/视图查询
解决方法:
SQL> select * from dba_synonyms t where t.synonym_name = 'V$CLIENT_STATS';
OWNER SYNONYM_NAME TABLE_OWNER TABLE_NAME DB_LINK
------------------------------ ------------------------------ ------------------------------ ------------------------------ -----------
PUBLIC V$CLIENT_STATS SYS V_$CLIENT_STATS
SQL> grant select on V_$CLIENT_STATS to zhangbin;
Grant succeeded
切换到普通用户
SQL> show user;
User is "zhangbin"
SQL> create or replace procedure p_test
2 as
3 v_all number :=9999;
4 begin
5 select count(1)
6 into v_all
7 from v$client_stats;
8 dbms_output.put_line('v_all =' ||v_all );
9 end;
10 /
Procedure created
SQL> set serveroutput on
SQL> exec p_test;
v_all =0
PL/SQL procedure successfully completed
