Sélectionnez la taille de la base de données SQL Server

comment puis-je interroger mon serveur SQL pour obtenir uniquement la taille de la base de données? 

J'ai utilisé ceci: 

use "MY_DB"
exec sp_spaceused

J'ai eu ceci:

database_name   database_size   unallocated space
My_DB           17899.13 MB 5309.39 MB

Il me renvoie plusieurs colonnes dont je n'ai pas besoin, peut-être y at-il une astuce pour sélectionner la colonne database_size dans cette procédure stockée? 

J'ai aussi essayé ce code:

SELECT DB_NAME(database_id) AS DatabaseName,
       Name AS Logical_Name,
       Physical_Name,
       (size * 8) / 1024 SizeMB
FROM sys.master_files
WHERE DB_NAME(database_id) = 'MY_DB'

Cela me donne ce résultat:

DatabaseName    Logical_Name    Physical_Name                    SizeMB
MY_DB           MY_DB           D:\MSSQL\Data\MY_DB.mdf          10613
MY_DB           MY_DB_log       D:\MSSQL\Data\MY_DB.ldf          7286

Alors j'ai écrit ceci: 

SELECT SUM(SizeMB)
FROM (
    SELECT DB_NAME(database_id) AS DatabaseName,
           Name AS Logical_Name,
           Physical_Name,
           (size * 8) / 1024 SizeMB
    FROM sys.master_files
    WHERE DB_NAME(database_id) = 'MY_DB'
) AS TEMP

J'ai eu: 1183

Cela fonctionne donc, mais peut-être existe-t-il un moyen approprié de l'obtenir?

Comparez également les résultats avec le résultat de la requête suivante

EXEC sp_helpdb @dbname= 'MSDB'

Il produit un résultat similaire à celui-ci
