Hi, all
I am trying to drop a queue table and I can not.
When I do select table_name from user_tables and I can see the table is there, but when I do drop table command, it tells me to use DBMS_AQADM.DROP_QUEUE_TABLE to drop the queue table. But when I use DBMS_AQADM.DROP_QUEUE_TABLE to drop the table, it says the table does not exists. Can anyone tell me why? and what should I do? Thanks for help.

SQL> execute DBMS_AQADM.DROP_QUEUE_TABLE('VLAD_IN_T');
BEGIN DBMS_AQADM.DROP_QUEUE_TABLE('VLAD_IN_T'); END;
