可以结合sp_msforeachdb再遍历所有用户数据库查看所有表的尺寸大小,注意它的参数@sql不能超过nvarchar(2000),这里就不贴出代码了。
另外还可以定期运行并将结果保存下来,以便观察数据变化趋势。
查询单个数据库的所有用户表尺寸大小:
复制代码 代码如下:
select @@servername as servername,db_name() as dbname ,object_id as objectid, schema_name(schema_id) as schname, name as tablename
,rowcnt as rows,columns,indexes,rowlength
,reservedkb, tableusedkb
,usedkb-tableusedkb as indexusedkb,reservedkb-usedkb as unusedkb
,create_date as createdate,modify_date as lastmodifieddate, getutcdate() as trackingutctime
from
(select
object_id
,schema_id
,name
,(select max(row_count) from sys.dm_db_partition_stats p with(nolock) where p.object_id=t.object_id and p.index_id < 2) as rowcnt
,(select count(1) from dbo.syscolumns with(nolock) where id = t.object_id) as columns
,(select count(distinct index_id) from sys.dm_db_partition_stats p with(nolock) where p.object_id=t.object_id) as indexes
,(select sum(length) from dbo.syscolumns with(nolock) where id = t.object_id) as rowlength
,isnull((select sum(reserved_page_count) from sys.dm_db_partition_stats p with(nolock) where p.object_id=t.object_id),0)*8
+ isnull((select sum(reserved_page_count)

where it.parent_id = t.object_id
and it.internal_type in (202,204,207,211,212,213,214,215,216,221,222,236)),0)* 8 as reservedkb
