【Oracle】-【show_space和show_space_asm】-執行儲存過程報錯

Sys建立show_space()和show_space_asm()。

Bisal執行提示：

SQL> exec show_space('MY_OBJECTS', 'BISAL');

BEGIN show_space('MY_OBJECTS', 'BISAL'); END;

*

ERROR at line 1:

ORA-06550: line 1, column 7:

PLS-00201: identifier 'SHOW_SPACE' must be declared

ORA-06550: line 1, column 7:

PL/SQL: Statement ignored

Sys使用者執行：grant execute on show_space to bisal，bisal還是無法執行。

Sys使用者執行：

SQL> create public synonym show_space for sys.show_space;

Synonym created.

SQL> grant execute on show_space to public ;

Grant succeeded.

Bisal執行：

SQL> exec show_space('MY_OBJECTS', 'BISAL');
