需要對錶大資料量操作的時候，如delete，需要對索引可以選擇性的操作！可以使用下面語句生成:
declare @tname varchar(100)
declare @size int
set @size=0 --這裡設定索引大小限制，如果不設定預設為0即所有索引
set @tname='tblorders'
select 'alter index '+' '+c.indexname+' '+'on'+' '+@tname+' '+'rebuild with (data_compression=page)'
from
(select * from
(select
object_name(i.object_id) as tablename,
i.name as indexname,
i.index_id as indexid,
8 * sum(a.used_pages)/1024 as 'indexsize(mb)'
from sys.indexes as i
join sys.partitions as p on p.object_id = i.object_id and p.index_id = i.index_id
join sys.allocation_units as a on a.container_id = p.partition_id
group by i.object_id,i.index_id,i.name
)awhere a.tablename=@tname and
[indexsize(mb)]>@size )c
