Menampilkan informasi tentang semua file database di SQL Server

Apakah mungkin untuk membuat daftar informasi tentang file (MDF / LDF) dari semua database di SQL Server?

Saya ingin mendapatkan daftar yang menunjukkan database mana yang menggunakan file apa di disk lokal.

Apa yang saya coba:

• exec sp_databases semua database
• select * from sys.databases menunjukkan banyak informasi tentang setiap database - tetapi sayangnya tidak menampilkan file yang digunakan oleh setiap database.
• select * from sys.database_filesmenampilkan file mdf / ldf dari masterdatabase - tetapi bukan database lainnya

Anda dapat menggunakan sys.master_files .

Berisi satu baris per file dari database seperti yang disimpan di database master. Ini adalah tampilan tunggal untuk seluruh sistem.

Jika Anda ingin mendapatkan lokasi Database Anda dapat memeriksa Get All DBs Location .
Anda dapat menggunakan sys.master_filesuntuk mendapatkan lokasi db dan sys.databseuntuk mendapatkan nama db

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

Saya menggunakan skrip untuk mendapatkan ruang kosong di setiap file:

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

Saya telah membuat kueri ini:

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

Anda juga bisa mencobanya.

 select db_name(dbid) dbname, filename from sys.sysaltfiles

Menjalankan sql berikut (Ini hanya akan berfungsi jika Anda tidak memiliki banyak file mdf / ldf untuk database yang sama)

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

akan mengembalikan keluaran ini

DBName       DataFile                     LogFile
--------------------------------------------------------------------------------
master       C:\....\master.mdf           C:\....\mastlog.ldf
tempdb       C:\....\tempdb.mdf           C:\....\templog.ldf
model        C:\....\model.mdf            C:\....\modellog.ldf

dan database lainnya

Jika TempDB Anda memiliki beberapa MDF (seperti milik saya), skrip ini akan gagal. Namun, Anda bisa menggunakan

WHERE db.database_id > 4

pada akhirnya dan itu akan mengembalikan semua database kecuali database sistem.

Dengan menggunakan skrip ini, Anda dapat menampilkan semua nama database dan file yang digunakan (dengan pengecualian dbs sistem).

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

Skrip ini mencantumkan sebagian besar dari apa yang Anda cari dan mudah-mudahan dapat dimodifikasi sesuai kebutuhan Anda. Perhatikan bahwa itu membuat tabel permanen di sana - Anda mungkin ingin mengubahnya. Ini adalah bagian dari skrip yang lebih besar yang juga merangkum informasi cadangan dan pekerjaan di berbagai server.

Query akan error jika beberapa file data (misalnya tipe file ".ndf") digunakan dalam salah satu database.

Berikut adalah versi kueri Anda menggunakan gabungan, bukan sub-kueri.

Bersulang!

hanya menambahkan 2 sen saya.

jika secara khusus mencari total ruang kosong hanya di file Data atau hanya di file Log di semua database, kita dapat menggunakan kolom "data_space_id". 1 untuk file data dan 0 untuk file log.

KODE:

Create Table ##temp

    DatabaseName sysname,
    Name sysname,
    spacetype sysname,
    physical_name nvarchar(500),
    size decimal (18,2),

Insert Into ##temp (DatabaseName, Name,spacetype, physical_name, Size, FreeSpace)
    Select DB_NAME() AS [DatabaseName], Name,   ***data_space_id*** , physical_name,

        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 

Jika Anda mengganti nama Database Anda, MS SQL Server tidak mengganti nama file yang mendasarinya.

Kueri berikut memberi Anda nama saat ini dari database dan nama file logis (yang mungkin merupakan nama asli dari database saat dibuat) dan juga nama file fisik yang sesuai.

Catatan: Hapus komentar baris terakhir untuk melihat hanya file data yang sebenarnya

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'
