一、首先，查找"维护计划"对象的ID
复制代码 代码示例:
use msdb
select * from sysmaintplan_plans
select * from sysmaintplan_log
select * from sysmaintplan_subplans
二、然后，根据ID号删除相应的"维护计划"
复制代码 代码示例:
delete from sysmaintplan_log where plan_id = ' ‘
delete from sysmaintplan_subplans where subplan_id = ' '
delete from sysmaintplan_plans where id = ' '
