列出SQL Server中所有数据库文件的信息

这个脚本列出了大部分你需要的内容，并希望能根据你的需求进行修改。请注意，它在其中创建了一个永久表 - 你可能需要更改它。它是一个较大脚本的子集，还总结了各种服务器上的备份和作业信息。

如果您重命名数据库，MS SQL Server不会重命名底层文件。
以下查询将为您提供数据库的当前名称和逻辑文件名（可能是创建数据库时的原始名称），以及相应的物理文件名。
注意：取消注释最后一行，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，还可以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);
'

只是添砖加瓦。

如果特别想要在所有数据库中仅查找数据文件或日志文件的总可用空间，可以使用"data_space_id"列。1表示数据文件，0表示日志文件。

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
