Finding Database and Table Size for all list of Tables in Sql server 2008 and Above

I have found a very good question discussion about how to find database physical size and table physical size using SQL Query. This query also returns number of rows and data size for each table in MB and GBs.


==================== Query ===============================


-- Script to analyze table space usage using the
-- output from the sp_spaceused stored procedure
-- Works with SQL 7.0, 2000, and 2005, 2008, R2

set nocount on


print 'Show Size, Space Used, Unused Space, Type, and Name of all database files'

select
[FileSizeMB] =
convert(numeric(10,2),sum(round(a.size/128.,2))),
        [UsedSpaceMB] =
convert(numeric(10,2),sum(round(fileproperty( a.name,'SpaceUsed')/128.,2))) ,
        [UnusedSpaceMB] =
convert(numeric(10,2),sum(round((a.size-fileproperty( a.name,'SpaceUsed'))/128.,2))) ,
[Type] =
case when a.groupid is null then '' when a.groupid = 0 then 'Log' else 'Data' end,
[DBFileName] = isnull(a.name,'*** Total for all files ***')
from
sysfiles a
group by
groupid,
a.name
with rollup
having
a.groupid is null or
a.name is not null
order by
case when a.groupid is null then 99 when a.groupid = 0 then 0 else 1 end,
a.groupid,
case when a.name is null then 99 else 0 end,
a.name
