select [VM_ID], datediff(hour,min([REC_COLLECTION_DATE_TS]),max([REC_COLLECTION_DATE_TS]))/24.0 as SHUTDOWN_DAYS,
max([REC_COLLECTION_DATE_TS])-min([REC_COLLECTION_DATE_TS]) as DIFF_COLLECTION_DATE_TS
from ( SELECT [VM_FCT_ID]
,sum([PowerState]) OVER ( partition by [VM_ID] ORDER BY [REC_COLLECTION_DATE_TS] desc ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW ) rn
FROM [T_FCT_VCENTER_VM] where [PowerState] is not null and VM_ID in (SELECT [VM_ID]
FROM [T_DIM_VCENTER_VM] where UPDATED_FLAG =1 and PowerState='PoweredOff')
) a where rn=0
group by [VM_ID]
) as a
inner join T_DIM_VCENTER_VM d on a.VM_ID = d.VM_ID
