是否可以列出有关 SQL Server 上所有数据库的文件 (MDF/LDF) 的信息？
我想获得一个列表，显示哪个数据库正在使用本地磁盘上的哪些文件。
我尝试了什么：
exec sp_databases所有数据库select * from sys.databases显示了有关每个数据库的大量信息 - 但不幸的是，它没有显示每个数据库使用的文件。select * from sys.database_files显示master数据库的 mdf/ldf 文件 - 但不显示其他数据库

您可以使用sys.master_files。
包含存储在主数据库中的数据库的每个文件的行。这是一个单一的、系统范围的视图。

If you want get location of Database you can check Get All DBs Location.
you can use sys.master_files for get location of db and sys.database to get db name
SELECT
db.name AS DBName,
type_desc AS FileType,
Physical_Name AS Location
FROM
sys.master_files mf
INNER JOIN
sys.databases db ON db.database_id = mf.database_id

我正在使用脚本在每个文件中获取空白空间：
Create Table ##temp
(
DatabaseName sysname,
Name sysname,
physical_name nvarchar(500),
size decimal (18,2),
FreeSpace decimal (18,2)
)
Exec sp_msforeachdb '
Use [?];
Insert Into ##temp (DatabaseName, Name, physical_name, Size, FreeSpace)
Select DB_NAME() AS [DatabaseName], Name, physical_name,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) as nvarchar) Size,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) -
Cast(FILEPROPERTY(name, ''SpaceUsed'') * 8.0/1024.0 as decimal(18,2)) as nvarchar) As FreeSpace
From sys.database_files
'
Select * From ##temp
drop table ##temp

Executing following sql (It will only work when you don't have multiple mdf/ldf files for same database)
SELECT
db.name AS DBName,
(select mf.Physical_Name FROM sys.master_files mf where mf.type_desc = 'ROWS' and db.database_id = mf.database_id ) as DataFile,
(select mf.Physical_Name FROM sys.master_files mf where mf.type_desc = 'LOG' and db.database_id = mf.database_id ) as LogFile
FROM sys.databases db
will return this output
DBName DataFile LogFile
--------------------------------------------------------------------------------
master C:\....\master.mdf C:\....\mastlog.ldf
tempdb C:\....\tempdb.mdf C:\....\templog.ldf
model C:\....\model.mdf C:\....\modellog.ldf
and rest of the databases
If your TempDB's have multiple MDF's (like mine have), this script will fail. However, you can use
WHERE db.database_id > 4
at the end and it will return all databases except system databases.

我创建了这个查询：
SELECT
db.name AS [Database Name],
mf.name AS [Logical Name],
mf.type_desc AS [File Type],
mf.physical_name AS [Path],
CAST(

) / 1024.0 AS DECIMAL(18, 1)) AS [Initial Size (MB)],
'By '+IIF(
mf.is_percent_growth = 1, CAST(mf.growth AS VARCHAR(10))+'%', CONVERT(VARCHAR(30), CAST(
(mf.growth * 8
) / 1024.0 AS DECIMAL(18, 1)))+' MB') AS [Autogrowth],
IIF(mf.max_size = 0, 'No growth is allowed', IIF(mf.max_size = -1, 'Unlimited', CAST(
(
CAST(mf.max_size AS BIGINT) * 8
) / 1024 AS VARCHAR(30))+' MB')) AS [MaximumSize]
FROM
sys.master_files AS mf
INNER JOIN sys.databases AS db ON
db.database_id = mf.database_id

You can also try this.

This script lists most of what you are looking for and can hopefully be modified to you needs. Note that it is creating a permanent table in there - you might want to change it. It is a subset from a larger script that also summarises backup and job information on various servers.

当存在多个数据文件（例如“.ndf”文件类型）时，要绕过查询哪个错误，试试这个版本，它用连接替换子查询。
这是使用联接而不是子查询的查询版本。
干杯!
SELECT
db.name AS DBName,
db.database_id,
mfr.physical_name AS DataFile,
mfl.physical_name AS LogFile
FROM sys.databases db
JOIN sys.master_files mfr ON db.database_id=mfr.database_id AND mfr.type_desc='ROWS'
JOIN sys.master_files mfl ON db.database_id=mfl.database_id AND mfl.type_desc='LOG'
ORDER BY db.database_id
示例结果：（请注意，单个日志文件与单个数据库的每个 MDF 和 NDF 配对）

如果重命名数据库，MS SQL Server 不会重命名基础文件。
以下查询为您提供数据库的当前名称和逻辑文件名（可能是数据库创建时的原始名称）以及相应的物理文件名。
注意：取消注释最后一行以仅查看实际数据文件
select db.database_id,
db.name "Database Name",
files.name "Logical File Name",
files.physical_name
from sys.master_files files
join sys.databases db on db.database_id = files.database_id
-- and files.type_desc = 'ROWS'

使用 sp_MSForEachDB 存储过程是一种选择
EXEC sp_MSForEachDB 'use ? select * from sys.database_files'
此外，仅查看完整路径名称和大小信息
EXEC sp_MSForEachDB '
USE [?];
SELECT DB_NAME() AS DbName,
physical_name AS FullPath,
name AS FileName,
type_desc,
size/128.0 AS CurrentSizeMB,
size/128.0 - CAST(FILEPROPERTY(name, ''SpaceUsed'') AS INT)/128.0 AS FreeSpaceMB
FROM sys.database_files
WHERE type IN (0,1);

只需加上我的 2 美分。
如果专门寻找仅在数据文件中或仅在所有数据库的日志文件中查找总可用空间，我们可以使用“data_space_id”列。1 用于数据文件，0 用于日志文件。
代码：
Create Table ##temp
(
DatabaseName sysname,
Name sysname,
spacetype sysname,
physical_name nvarchar(500),
size decimal (18,2),
FreeSpace decimal (18,2)
)
Exec sp_msforeachdb '
Use [?];
Insert Into ##temp (DatabaseName, Name,spacetype, physical_name, Size, FreeSpace)
Select DB_NAME() AS [DatabaseName], Name, ***data_space_id*** , physical_name,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2))/1024 as nvarchar) SizeGB,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2)/1024 as decimal(18,2)) -
Cast(FILEPROPERTY(name, ''SpaceUsed'') * 8.0/1024.0 as decimal(18,2))/1024 as nvarchar) As FreeSpaceGB
From sys.database_files'
select
databasename
, sum(##temp.FreeSpace)
from
##temp
where
##temp.spacetype = 1
group by
DatabaseName
drop table ##temp
