额，写了一个存储过程，看能满足你的需求不？
DECLARE
TYPE name_list IS TABLE OF VARCHAR2(40);
TYPE type_list IS TABLE OF VARCHAR2(20);
Tab_name name_list := name_list();
Tab_type type_list := type_list();
sql_str VARCHAR2(500);
BEGIN
sql_str := 'select uo.object_name,uo.object_type from user_objects uo where uo.object_type not in(''INDEX'',''LOB'') and uo.object_name not like ''BIN$%'' order by uo.object_type desc';
EXECUTE IMMEDIATE sql_str BULK COLLECT
INTO tab_name, tab_type;
FOR i IN Tab_name.FIRST .. Tab_name.LAST LOOP
sql_str := 'DROP ' || Tab_type(i) || ' "' || Tab_name(i) || '"';
EXECUTE IMMEDIATE sql_str;
END LOOP;
END;
