从使用OSQL的命令提示符：

OSQL -E -d <*databasename*> -Q "exec sp_msforeachtable 'sp_spaceused [?]'" > result.txt

我在marc_s答案的顶部添加了几列：

with fs
as
(
select i.object_id,
        p.rows AS RowCounts,
        SUM(a.total_pages) * 8 AS TotalSpaceKb
from     sys.indexes i INNER JOIN 
        sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id INNER JOIN 
         sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    i.OBJECT_ID > 255 
GROUP BY 
    i.object_id,
    p.rows
)

SELECT 
    t.NAME AS TableName,
    fs.RowCounts,
    fs.TotalSpaceKb,
    t.create_date,
    t.modify_date,
    ( select COUNT(1)
        from sys.columns c 
        where c.object_id = t.object_id ) TotalColumns    
FROM 
    sys.tables t INNER JOIN      
    fs  ON t.OBJECT_ID = fs.object_id
WHERE 
    t.NAME NOT LIKE 'dt%' 
    AND t.is_ms_shipped = 0
ORDER BY 
    t.Name

这将为您提供每个表的大小和记录计数。

如果您只关心数据库中的空浪费空间，而不关心单个表，则可以考虑以下问题：

如果数据库经历了大量的数据插入和删除，可能与ETL情况类似，这将导致数据库中有太多未使用的空间，因为文件组会自动增长，但不会自动收缩。

您可以通过使用数据库的财产页面来查看是否是这种情况。您可以收缩（右键单击数据库>任务>收缩）并收回一些空间。但是，如果根本原因仍然存在，则数据库将增长（并花费额外的时间尝试增长，直到增长到足够的速度，所以不要这样做）

以上查询有助于查找表（包括索引）使用的空间量，但如果要比较表上的索引使用了多少空间，请使用以下查询：

SELECT
    OBJECT_NAME(i.OBJECT_ID) AS TableName,
    i.name AS IndexName,
    i.index_id AS IndexID,
    8 * SUM(a.used_pages) AS 'Indexsize(KB)'
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
WHERE
    i.is_primary_key = 0 -- fix for size discrepancy
GROUP BY
    i.OBJECT_ID,
    i.index_id,
    i.name
ORDER BY
    OBJECT_NAME(i.OBJECT_ID),
    i.index_id

我的文章只与SQL Server 2000相关，并且已经过测试，可以在我的环境中工作。

该代码访问单个实例的所有可能的数据库，而不仅仅是单个数据库。

我使用两个临时表来帮助收集适当的数据，然后将结果转储到一个“Live”表中。

返回的数据是：DatabaseName、DatabaseTableName、Rows（在表中）、data（表的大小，以KB为单位）、entry data（我发现这对了解我上次运行脚本的时间很有用）。

这段代码的缺点是“data”字段不是以int形式存储的（字符“KB”保留在该字段中），这对于排序是有用的（但不是完全必要的）。

希望这段代码能帮助一些人，并为他们节省一些时间！

    [DatabaseName] [varchar](1000) NULL,
    [dbSize] [decimal](15, 2) NULL,
    [DateUpdated] [smalldatetime] NULL
