表或视图不存在

Question

您好,以下是我的代码.我需要使用视图中的数据创建一个视图并在另一个游标中获取数据.但是当我执行我的代码时,我收到错误

"ORA-06550:第56行,第37列:PL/SQL:ORA-00942:表或视图不存在ORA-06550:第52行,第9列:PL/SQL:忽略SQL语句"

这是什么问题？提前致谢.

您正在尝试访问TABLE/VIEW使用相同块中的动态 创建的(静态)SQLSELECTSQL

每个PL/SQLBlock都会在执行之前编译.虽然编译不可用!rv_task_number_view

所以,SELECT需要也是动态的!

  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';
