TODO:
You want to find tables that contain large amounts of data, which can be due to large row counts. The solution will get table stats, and sort by row count descending.
SOLUTION:
SELECT
t.NAME AS 'Table',
i.name as 'Index',
sum(p.rows) as 'Rows',
sum(a.total_pages) as 'Total Pages',
sum(a.used_pages) as 'Used Pages',
sum(a.data_pages) as 'Data Pages',
(sum(a.total_pages) * 8) / 1024 as 'Total Space (MB)',
(sum(a.used_pages) * 8) / 1024 as 'Used Space (MB)',
(sum(a.data_pages) * 8) / 1024 as 'Data Space (MB)'
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
i.OBJECT_ID > 255 AND
i.index_id <= 1
GROUP BY
t.NAME, i.object_id, i.index_id, i.name
ORDER BY
Rows DESC
