表或視圖不存在

Question

以下給出的是我的代碼。我需要創建一個視圖，並使用視圖中的數據在另一個遊標中獲取數據。但是，當我執行我的代碼，我得到的錯誤

「ORA-06550：行56，列37： PL/SQL：ORA-00942：表或視圖不存在 ORA-06550：行52，第9列： PL/SQL：SQL語句被忽略「

這裏有什麼問題？ 在此先感謝。

您試圖訪問使用創造了一個TABLE/VIEW一個動態SQL在同一塊地方，你SELECT它（靜態SQL）

每PL/SQL座沃爾德是前執行編譯。 雖然彙編rv_task_number_view不可用！

因此，SELECT也需要動態！

C2 SYS_REFCURSOR; 

    OPEN C2 FOR 

    'SELECT ct.task_id,jtf_note_id, jnv.notes, 
      jnv.creation_date,jnv.last_update_date 
     FROM 
      jtf_notes_vl jnv, 
      csf_ct_tasks ct,apps.rv_task_number_view rvt 
     WHERE 
      jnv.source_object_code = ''TASK'' 
      and ct.task_number = jnv.source_number 
      and ct.task_number = rvt.task_number 
      order by task_id, jtf_note_id';
