SQL Server 参考sql2012存储过程写的统计所有用户表尺寸大小

这篇文章主要为大家详细介绍了SQL Server 参考sql2012存储过程写的统计所有用户表尺寸大小，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小编两巴掌来看看吧！

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：

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)
                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
