参考说明:

If the referenced item is indeed declared and you believe that you have privileges to refer to that item, check the privileges; if the privileges were granted only via a role, then this is expected and documented behavior. Stored objects (packages, procedures, functions, triggers, views) run in the security domain of the object owner with no roles enabled except PUBLIC. Again, you will be notified only that the item was not declared
