Seseorang tidak dapat memberikan akses langsung V$session karena v$session adalah sinonim. Hal yang sama berlaku untuk v$instance
Sebenarnya ini berlaku untuk semua tampilan v$ yang semuanya sinonim
SQL> GRANT SELECT ON v$session TO test_user; grant select on v$session to test_user * ERROR at line 1: ORA-02030: can only select from fixed tables/views SQL> GRANT SELECT ON v$instance TO test_user; grant select on v$instance to test_user * ERROR at line 1: ORA-02030: can only select from fixed tables/views
Kueri untuk menunjukkan V$SESSION adalah sinonim publik
SQL> SELECT owner, object_type FROM dba_objects WHERE object_name = ‘V$SESSION’; OWNER OBJECT_TYPE ———————— ——————- PUBLIC SYNONYM SQL> SELECT owner, object_type FROM dba_objects WHERE object_name = ‘V$INSTANCE’; OWNER OBJECT_TYPE ———————— ——————- PUBLIC SYNONYM
Permintaan untuk menunjukkan objek (tabel/tampilan) yang ditunjuk oleh sinonim
SQL> select table_owner, table_name FROM dba_synonyms where synonym_name = ‘V$SESSION’; TABLE_OWNER TABLE_NAME ————– —————————— SYS V_$SESSION SQL> select table_owner, table_name FROM dba_synonyms where synonym_name = ‘V$SESSION’; TABLE_OWNER TABLE_NAME ————– —————————— SYS V_$INSTANCE
Cara memberikan akses ke tampilan v$
Kami dapat memberikan akses ke tampilan ini dengan memberikan akses pemberian pada tabel/tampilan yang mendasarinya.
jadi untuk V$session, kami perlu memberikan pilihan pada v_$session. Demikian pula untuk tampilan lain, kita harus melakukan hal yang sama
SQL> GRANT SELECT ON V_$SESSION TO test_user; Grant succeeded. SQL> GRANT SELECT ON V_$INSTANCE TO test_user; Grant succeeded.
Catatan:Langkah yang sama dapat digunakan untuk menemukan tampilan V$ lainnya dan akses dapat diberikan tergantung pada representasi internal
Berikut adalah beberapa tampilan v$ dengan nama sinonim dan nama tabel. kita perlu menggunakan tabel untuk memberikan akses ke pengguna, jika kita mencoba dengan nama sinonim, kita akan mendapatkan kegagalan yang sama untuk semua tampilan ini

Semoga Anda menyukai artikel singkat tentang grant select di v_$session. Hal yang sama dapat dijalankan untuk memberikan akses pada v$views apa pun. Semoga Anda menyukai posting ini. Harap berikan umpan balik
