这是Management Studio用来填充这些数字的查询：
SELECT
(SELECT SUM(CAST(df.size as float)) FROM sys.database_files AS df
WHERE df.type in ( 0, 2, 4 ) ) AS [DbSize],
SUM(a.total_pages) AS [SpaceUsed],
(SELECT SUM(CAST(df.size as float)) FROM sys.database_files AS df
WHERE df.type in (1, 3)) AS [LogSize]
FROM
sys.partitions p join sys.allocation_units a
on p.partition_id = a.container_id
left join sys.internal_tables it
on p.object_id = it.object_id
您需要像Management Studio一样在这里执行数学运算才能获得相同的数字。另外，左连接sys.internal_tables最多似乎是多余的。因此，调整该查询以匹配您的理想输出：
SELECT
(SELECT CONVERT(DECIMAL(18,2), SUM(CAST(df.size as float))*8/1024.0)
FROM sys.database_files AS df
WHERE df.type in ( 0, 2, 4 ) ) AS [DbSize],
CONVERT(DECIMAL(18,2), SUM(a.total_pages)*8/1024.0) AS [SpaceUsed],
(SELECT CONVERT(DECIMAL(18,2), SUM(CAST(df.size as float))*8/1024.0)
FROM sys.database_files AS df
WHERE df.type in (1, 3)) AS [LogSize]
FROM sys.partitions p join sys.allocation_units a
on p.partition_id = a.container_id;
通过此更新，假设您的数据库在此期间未发生变化，则应产生：
753475.94 744030.07 2900.00做一些简单的数学运算，并仅隔离所需的三个数字：
;WITH t(s) AS
(
SELECT CONVERT(DECIMAL(18,2), SUM(size)*8/1024.0)
FROM sys.database_files
WHERE [type] % 2 = 0
),
d(s) AS
(
SELECT CONVERT(DECIMAL(18,2), SUM(total_pages)*8/1024.0)
FROM sys.partitions AS p
INNER JOIN sys.allocation_units AS a
ON p.[partition_id] = a.container_id
)
SELECT
Allocated_Space = t.s,
Available_Space = t.s - d.s,
[Available_%] = CONVERT(DECIMAL(5,2), (t.s - d.s)*100.0/t.s)
FROM t CROSS APPLY d;
Aaron的查询很好，但作为替代，我使用Glenn Berry的DMV查询中的此查询
（您需要更改TB的数学方法）：
-- Individual File Sizes and space available for current database
-- (Query 36) (File Sizes and Space)
SELECT f.name AS [File Name] , f.physical_name AS [Physical Name],
CAST((f.size/128.0) AS DECIMAL(15,2)) AS [Total Size in MB],
CAST(f.size/128.0 - CAST(FILEPROPERTY(f.name, 'SpaceUsed') AS int)/128.0 AS DECIMAL(15,2))
AS [Available Space In MB], [file_id], fg.name AS [Filegroup Name]
FROM sys.database_files AS f WITH (NOLOCK)
LEFT OUTER JOIN sys.data_spaces AS fg WITH (NOLOCK)
ON f.data_space_id = fg.data_space_id OPTION (RECOMPILE);
这是一些可能适合您的SQL。
Create Table #dbInfo (dId smallint, dbName sysname, gId smallint NULL, segName varchar(256) NULL,
filName varchar(520) NULL, sizeMg decimal(10,2) null,
usedMg decimal(10,2) null, freeMg decimal(10,2) null,
pcntUsed decimal(10,2) null, pcntFree decimal(10,2) null)
Declare @sSql varchar(1000)
Set @sSql = 'Use [?];
Insert #dbInfo (dId, dbName, gid, segName, filName, sizeMg, usedMg)
Select db_id(), db_name(), groupid, rtrim(name), filename, Cast(size/128.0 As Decimal(10,2)),
Cast(Fileproperty(name, ''SpaceUsed'')/128.0 As Decimal(10,2))
From dbo.sysfiles Order By groupId Desc;'
Exec sp_MSforeachdb @sSql
Update #dbInfo Set
freeMg = sizeMg - usedMg,
pcntUsed = (usedMg/sizeMg)*100,
pcntFree = ((sizeMg-usedMg)/sizeMg)*100
select * from #dbInfo compute sum(sizeMG), sum(FreeMg)
drop table #dbInfo
它是旧的SQL，但仍然有效。这些天之一，我将重写它以使用sys.database_files，如Aaron的回答。
在处理了类似的问题（查询真实的物理数据库文件大小）之后，我认为一个显示不同文件大小的查询（例如，按日志和数据库分开）以及磁盘上文件的大小将对大多数用户有所帮助。
这包括系统文件大小以及它在磁盘上占用的空间，以及SQL文件大小，使用的SQL空间以及扩展的SQL可用空间。它包括要评估的文件的完整路径。如果使用与默认值（4096字节）不同的分配大小来格式化磁盘，则用户将需要更改“ Size_On_Disk_Bytes”的计算。
SELECT fg.data_space_id AS FGID,
(f.file_id) AS File_Id,
-- As provided by OP, size on disk in bytes.
REPLACE(CONVERT(VARCHAR,CONVERT(MONEY, CAST(f.size AS FLOAT) * 8.00 * 1024), 1), '.00','') AS Size_On_Disk_Bytes,
ROUND((CAST(f.size AS FLOAT) * 8.00/1024)/1024,3) AS Actual_File_Size,
ROUND(CAST((f.size) AS FLOAT)/128,2) AS Reserved_MB,
ROUND(CAST((FILEPROPERTY(f.name,'SpaceUsed')) AS FLOAT)/128,2) AS Used_MB,
ROUND((CAST((f.size) AS FLOAT)/128)-(CAST((FILEPROPERTY(f.name,'SpaceUsed'))AS FLOAT)/128),2) AS Free_MB,
f.name,
f.physical_name
FROM sys.database_files f
LEFT JOIN sys.filegroups fg
ON f.data_space_id = fg.data_space_id
此外，此查询将返回有关托管文件的卷驱动器上的空间的信息。用户将需要有权访问sys.master_files。
SELECT DISTINCT dovs.logical_volume_name AS LogicalName,
dovs.volume_mount_point AS Drive,
CONVERT(INT,dovs.available_bytes/1048576.0) AS FreeSpaceInMB
FROM sys.master_files mf
CROSS APPLY sys.dm_os_volume_stats(mf.database_id, mf.FILE_ID) dovs
ORDER BY FreeSpaceInMB ASC
我放在一起的东西。您需要在SQL Server上运行POWERSHELL。不确定版本。这将占用您的驱动器大小，并报告文件大小和可用空间以及可用驱动器空间。
它不是100％原始的，部分不是我在互联网上的其他地方找到的并将整个东西放在一起的。这是一个PITA，使其适合正确的页边距，因此您可能需要玩括号
