方法1：
drop user XXXX cascade;
drop tablespace XXXX INCLUDING CONTENTS;
方法2：
写存储过程实现
DECLARETYPE 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);BEGINsql_str := 'select uo.object_name,uo.object_type from user_objects uo where uo.object_type not in(''INDEX'',''LOB'') 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 LOOPsql_str := 'DROP ' || Tab_type(i) || ' ' || Tab_name(i);EXECUTE IMMEDIATE sql_str;END LOOP;END;
最方便的方法就是 drop user aaa cascade;然后重建用户。 如果你不想删除后重建用户，那就： select 'drop ' || object_type || ' ' || object_name || ';' from user_objects; 然后执行得出的结果即可。
