Summary of disk usage for all databases using SSMS

How can I see all disk usage of all my databases on a giv开发者_JAVA百科en SQL Server in one single query. I have around 15 different databases on my server and I want to see which one is using the maximum disk space.

I know I can see reports of Disk Usage per database in SSMS or logon to the server and see the size of MDF/LDF files but this seems like a pretty obvious feature that should come with SSMS and I cant seem to find it.

This stored procedure will help.

exec sp_helpdb;

You'll get something like this:

name      db_size       owner         dbid created     status                                                                                                                                                                                                                                                                          compatibility_level

To learn more about a particular database, do:

exec sp_helpdb DatabaseName;

I'm not aware of any built in way but you can use the (undocumented) sp_MSforeachdb procedure for this.

CREATE TABLE #files(
    [dbname] [sysname] NOT NULL,
    [name] [sysname] NOT NULL,
    [physical_name] [nvarchar](260) NOT NULL,
    [size] [int] NOT NULL,
    [max_size] [int] NOT NULL,
    [growth] [int] NOT NULL
)

EXEC sp_MSforeachdb ' 
insert into #files
select ''[?]'',name,physical_name,size,max_size,growth
from [?].sys.database_files'


SELECT [dbname]
      ,[name]
      ,[physical_name]
      ,[size]
      ,[max_size]
      ,[growth]
  FROM #files
