SQL Query database location and size

Posted on 2014-02-06
Last Modified: 2014-02-10
So I can find a query to give me the name and location;

SELECT name, physical_name AS current_file_location
FROM sys.master_files

But I want to add a column that gives me the size as well.

How do I do that, thanks? :)

There is a column called size in sys.master_files that should give you that.


To transform from 8K pages to MB or GB:

         SizeInMB = (size * 8 / 1024)
         SizeInGB = (size * 8 / 1024 / 1024)

      sys.master_files mf INNER JOIN sys.database_files df
        ON mf.[name] = df.[name]

oh crap.  sorry about that.  here you go:

    DatabaseName sysname,
    LogicalFileName sysname,
    PhysicalFileName nvarchar(500),
    FileSize decimal (18,2),
    FreeSpace decimal (18,2)
EXEC sp_msforeachdb '
      Use [?];
      Insert Into ##RESULTS (DatabaseName, LogicalFileName, PhysicalFileName, FileSize, 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

HAHA, was getting a syntax error, then I realised I had copied the top line as well.

Anyway, thanks for that... Worked like a charm :)

One more question, but happy to open other question if you want the points.

We are moving to IAAS very soon, but want to know how much data actually changes in any given time period so we can work out bandwidth for replication of the databases.

Do you have a query for that? Or a recommendation of how to get that info.

Thanks again, great help :)
