Hi:

I am totally confused why my "drop table .. " statement using dynamic sql does not work. The oracle user_name I login has dba privilege. And as a test, I am trying to drop table HPXAREA in schema CATALOG_MANAGEMENT; Here is how I tested:

SQL> select user from dual;

USER

WEBSTORE_OWNER SQL> select owner, object_name, object_type, status 2 from all_objects
3 where object_name ='HPXPKG_CATALOG_MANAGEMENT';

OWNER                          OBJECT_NAME
OBJECT_TYPE        STATUS

SYNONYM            VALID
WEBSTORE_OWNER                 HPXPKG_CATALOG_MANAGEMENT
PACKAGE            VALID
WEBSTORE_OWNER                 HPXPKG_CATALOG_MANAGEMENT      PACKAGE
BODY       VALID

SQL> select * from CATALOG_MANAGEMENT.HPXAREA 2 ;

AREAID          ZONEID A
LOCALE                                                       DELIVERYD
------------ --------- - -----------------------------------------------

02138                  T

SQL> drop table CATALOG_MANAGEMENT.HPXAREA;

Table dropped.

SQL> select * from CATALOG_MANAGEMENT.HPXAREA; select * from CATALOG_MANAGEMENT.HPXAREA

ERROR at line 1:

  4                                          'hpxarea');

6 /
DROP table CATALOG_MANAGEMENT.hpxarea;

SQL> So, why couldn't I drop the table?

Thanks.
