计算SQL Server中一组表的物理大小

Question

我有一组大约 30 个表，我想知道所有这些表（加上索引）在磁盘上的物理大小。

是否有比通过 SQL Server 2008 R2 中的 GUI 更简单的方法？

Answer 1

如果您想获取数据库中所有表的大小信息，您可以使用以下查询：

SELECT O.type_desc, 
       IndexSize.obj_name,
       I.name AS index_name,
       IndexSize.reserved_MB,
       IndexSize.used_MB,
       IndexSize.row_count,
       IndexSize.object_id,
       IndexSize.index_id
  FROM (
    SELECT QUOTENAME(OBJECT_SCHEMA_NAME(DDPS.object_id))+'.'+QUOTENAME(OBJECT_NAME(DDPS.object_id)) obj_name,
           SUM(DDPS.reserved_page_count)/128.0 AS reserved_MB,
           SUM(DDPS.used_page_count)/128.0 AS used_MB,
           SUM(row_count) AS row_count,
           DDPS.object_id,
           DDPS.index_id
      FROM sys.dm_db_partition_stats AS DDPS
     GROUP BY DDPS.object_id,DDPS.index_id
   )IndexSize
   JOIN sys.objects AS O
     ON IndexSize.object_id = O.object_id
   JOIN sys.indexes AS I
     ON IndexSize.object_id = I.object_id
    AND IndexSize.index_id = I.index_id;

它返回保留的兆字节和使用的兆字节以及数据库中每个索引的行数。第一列告诉您对象类型。这包括 system_tables 以及索引视图。如果您想要一个子集，请对该列进行过滤。

如果您不需要每个索引的详细信息，则可以改用此查询：

SELECT O.type_desc,
       ObjectSize.obj_name,
       ObjectSize.reserved_MB,
       ObjectSize.used_MB,
       ObjectSize.row_count
  FROM( 
    SELECT QUOTENAME(OBJECT_SCHEMA_NAME(IndexSize.object_id))+'.'+QUOTENAME(OBJECT_NAME(IndexSize.object_id)) obj_name,
           SUM(IndexSize.reserved_MB) AS reserved_MB, 
           SUM(IndexSize.used_MB) AS used_MB, 
           MAX(IndexSize.row_count) AS row_count, 
           IndexSize.object_id
      FROM(
        SELECT SUM(DDPS.reserved_page_count)/128.0 AS reserved_MB,
               SUM(DDPS.used_page_count)/128.0 AS used_MB,
               SUM(row_count) AS row_count,
               DDPS.object_id
          FROM sys.dm_db_partition_stats AS DDPS
         GROUP BY DDPS.object_id,DDPS.index_id
      )IndexSize
     GROUP BY IndexSize.object_id
  )ObjectSize
  JOIN sys.objects AS O
    ON ObjectSize.object_id = O.object_id

它提供相同的信息，但基于对象。同样，如果您对 system_tables 不感兴趣，则过滤对象类型。

如果您只对普通表感兴趣，您也可以使用“对象资源管理器详细信息”选项卡获取 SSMS 中的信息：

您可以通过在对象资源管理器中选择数据库中的表文件夹，然后按 来打开它F7。

您可能需要添加大小列。为此，只需右键单击列列表并选择要查看的列：

您可以使用sp_spaceused存储过程：

例如：

EXECUTE sp_spaceused 'Person.Person' 
EXECUTE sp_spaceused 'Person.Address'

给你这个：
