Query in the maintenance plan tables does not reflect reality

Hi all,

I am using SQL Server 2005 Enterprise Edition.

I want to get information about my maintenance plan using T-SQL but the results I get does not show the real maintenance plans state.

Here is my query :

select distinct msdb.dbo.sysmaintplan_plans.name AS PlanName , 
msdb.dbo.sysmaintplan_subplans.subplan_name AS SubplanName,
msdb.dbo.sysmaintplan_logdetail.line1 AS DetailLevel1,
msdb.dbo.sysmaintplan_logdetail.line2 AS DetailLevel2,
msdb.dbo.sysmaintplan_logdetail.line3 AS DetailLevel3,
msdb.dbo.sysmaintplan_logdetail.line4 AS DetailLevel4
from msdb.dbo.sysmaintplan_plans
left join msdb.dbo.sysmaintplan_subplans on msdb.dbo.sysmaintplan_subplans.plan_id = msdb.dbo.sysmaintplan_plans.id
left join msdb.dbo.sysmaintplan_log on msdb.dbo.sysmaintplan_log.plan_id = msdb.dbo.sysmaintplan_plans.id
left join msdb.dbo.sysmaintplan_logdetail on msdb.dbo.sysmaintplan_logdetail.task_detail_id = msdb.dbo.sysmaintplan_log.task_detail_id

And here is my result :

The problem is that some of the lines I get in this results are not true. Take the maintenance plan named 'MaintenancePlan_CH', for example, the results above show that there 6 different tasks, whereas in reality, there are only three : Check Database Integrity Task 1, Update Statistics Task and History Cleanup Task.

Do you guys have any ideas where the others lines are from? The Rebuild Index Task, Shrink Database Task and the Check Database Integrity Task (without the '1' at the end).

Thank you for your time.

Antoine.
