有時候這種指令還是蠻好用的，可以一次找出那些TABLE使用量是最高的
語法如下:
select schema_name(tab.schema_id) + '.' + tab.name as [table],
cast(sum(spc.used_pages * 8)/1024.00 as numeric(36, 2)) as used_mb,
cast(sum(spc.total_pages * 8)/1024.00 as numeric(36, 2)) as allocated_mb
from sys.tables tab
inner join sys.indexes ind
on tab.object_id = ind.object_id
inner join sys.partitions part
on ind.object_id = part.object_id and ind.index_id = part.index_id
inner join sys.allocation_units spc
on part.partition_id = spc.container_id
group by schema_name(tab.schema_id) + '.' + tab.name
order by sum(spc.used_pages) desc
