This statement tries to do something, such as dropping a table, that only the owner of the table or a user who has Database Administrator privileges can do. Check that the statement names the table you intended. If it does, you will have to get its owner or a DBA to execute this statement. To find out who to contact, you can query the system catalog as follows:
SELECT tabname, owner FROM systables WHERE tabid > 99; SELECT username FROM sysusers WHERE usertype = 'D'
