SQL2005的维护计划无法删除的解决方法

1.查看"维护计划"对象的id

use msdb

select * from sysmaintplan_plans
select * from sysmaintplan_log
select * from sysmaintplan_subplans

2.根据id号删除相应的"维护计划"

delete from sysmaintplan_log where plan_id = ' ‘
delete from sysmaintplan_subplans where subplan_id = ' '
delete from sysmaintplan_plans where id = ' '
