sp_spaceused - How to measure the size in GB in all the tables in SQL

Question

Following the discussion in How to measure table size in GB in a table in SQL, I\'m looking for a solution to measure the space used by all the tables of a SQL Server individual

I know this isn't exactly what you are asking for as it DOESN'T use sp_spaceused but this will provide the results you are after.

SELECT  
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB,
    ( SUM(a.total_pages) * 8 ) / 1024.0 AS TotalSpaceMB,
    (( SUM(a.total_pages) * 8 ) / 1024.0)/1024.0 AS TotalSpaceGB,
    SUM(a.used_pages) * 8 AS UsedSpaceKB,
    ( SUM(a.used_pages) * 8 ) / 1024.0 AS UsedSpaceMB,
    (( SUM(a.used_pages) * 8 ) / 1024.0) /1024.0 AS UsedSpaceGB,
    ( SUM(a.total_pages) - SUM(a.used_pages) ) * 8 AS UnusedSpaceKB,
    ( ( SUM(a.total_pages) - SUM(a.used_pages) ) * 8 ) / 1024.0 AS UnusedSpaceMB,
    (( ( SUM(a.total_pages) - SUM(a.used_pages) ) * 8 ) / 1024.0)/1024.0 AS UnusedSpaceGB,
   GROUPING(t.Name)
FROM    sys.tables t
    INNER JOIN sys.schemas s ON s.schema_id = t.schema_id
    INNER JOIN sys.indexes i ON t.OBJECT_ID = i.object_id
    INNER JOIN sys.partitions p ON i.object_id = p.OBJECT_ID
                                   AND i.index_id = p.index_id
    INNER JOIN sys.allocation_units a ON p.partition_id = a.container_id
WHERE   t.NAME NOT LIKE 'dt%'
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255
GROUP BY s.Name,
     t.Name,
    p.Rows
   WITH ROLLUP
   ORDER BY s.Name,
    t.Name

Let me know if you really need it to use sp_spaceused.
