sql查询数据库中所有表的记录条数，以及占用磁盘空间大小。

SELECT
TableName = obj.name,

FROM sys.objects obj
JOIN sys.indexes idx on obj.object_id = idx.object_id

JOIN sys.allocation_units alloc on alloc.container_id = prt.partition_id
WHERE
obj.type = 'U' AND idx.index_id IN (0, 1)
GROUP BY obj.name, prt.rows
ORDER BY SUM(alloc.used_pages)*8 DESC
