SUM(a.total_pages) * 8 AS TotalSpaceKB,
SUM(a.used_pages) * 8 AS UsedSpaceKB,
(SUM(a.total_pages) – SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM
sys.tables t
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
GROUPBY
t.Name, p.Rows, t.create_date,
t.modify_date
