  • 简单的语句统计所有用户表尺寸大小

    参考SQL2005, 2008和2012的系统存储过程master.sys.sp_spaceused代码后,写了下面一条语句来方便平时统计所有用户表尺寸大小。
    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:

    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)
    				FROM sys.dm_db_partition_stats p2 with(nolock)
    				inner join sys.internal_tables it with(nolock) on p2.object_id = it.object_id
    				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
    	,IsNull((Select SUM(in_row_data_page_count + lob_used_page_count + row_overflow_used_page_count)
    				 from sys.dm_db_partition_stats p with(nolock) where p.object_id=t.object_id and p.index_id < 2),0)* 8 as TableUsedKb
    	,IsNull((Select SUM(used_page_count) from sys.dm_db_partition_stats p with(nolock) where p.object_id=t.object_id),0)*8
    		+ IsNull((Select sum(used_page_count)
    				FROM sys.dm_db_partition_stats p2 with(nolock)
    				inner join sys.internal_tables it with(nolock) on p2.object_id = it.object_id
    				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 UsedKb
    	,create_date
    	,modify_date
    from sys.tables t with(nolock) 
    where Type='U'
    ) A
    order by ReservedKb desc
