Determine the file size of a database using t-sql

Determine the file size of a database using t-sql

In SQL Server there are a number of ways to determine how large a database is. Right clicking and selecting properties > files in management studio for example is probably the easiest. However if you do not have very high permissions on the database you are interested in this t-sql may be what you need. 

This script requires the least permissions of all the different methods I could find and is fairly simple which is a bonus.

select a.FILEID,
      [FILE_SIZE_MB] = convert(decimal(12,2),round(a.size/128.000,2)),
      [SPACE_USED_MB] = convert(decimal(12,2),round(fileproperty(a.name,'SpaceUsed')/128.000,2)),
      [FREE_SPACE_MB] = convert(decimal(12,2),round((a.size-fileproperty(a.name,'SpaceUsed'))/128.000,2)),
      NAME = left(a.NAME,15),
      FILENAME = left(a.FILENAME,30)
