Pruebe este script:enumerará la cantidad de filas y el espacio utilizado por las filas de datos (y el espacio total utilizado) para todas las tablas en su base de datos:
SELECT

SUM(a.total_pages) AS TotalPages,
SUM(a.used_pages) AS UsedPages,
SUM(a.data_pages) AS DataPages,
(SUM(a.total_pages) * 8) / 1024 AS TotalSpaceMB,
(SUM(a.used_pages) * 8) / 1024 AS UsedSpaceMB,
(SUM(a.data_pages) * 8) / 1024 AS DataSpaceMB
