Listing information about all database files in SQL Server

Question

Is it possible to list information about the files (MDF/LDF) of all databases on an SQL Server?

I\'d like to get a list showing which database is using what files on th

Answer 1

I've created this query:

SELECT 
    db.name AS                                   [Database Name], 
    mf.name AS                                   [Logical Name], 
    mf.type_desc AS                              [File Type], 
    mf.physical_name AS                          [Path], 
    CAST(
        (mf.Size * 8
        ) / 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

Answer 2

just adding my 2 cents .

if specifically looking to find total free space only in Data files or only in Log files in all the databases, we can use "data_space_id" column. 1 is for data files and 0 for log files.

CODE:

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 

Answer 3

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.

Answer 4

Using this script you can show all the databases name and files used (with exception of system dbs).

select name,physical_name from sys.master_files where database_id > 4

Answer 5

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.
