USE [YourDBName] -- replace your dbname 
GO 
SELECT 
s.Name AS SchemaName, 
t.Name AS TableName, 
p.rows AS RowCounts, 
CAST(ROUND((SUM(a.used_pages) / 128.00), 2) AS NUMERIC(36, 2)) AS Used_MB, 
CAST(ROUND((SUM(a.total_pages) - SUM(a.used_pages)) / 128.00, 2) AS NUMERIC(36, 2)) AS Unused_MB, 
CAST(ROUND((SUM(a.total_pages) / 128.00), 2) AS NUMERIC(36, 2)) AS Total_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 
INNER JOIN sys.schemas s ON t.schema_id = s.schema_id 
GROUP BY t.Name, s.Name, p.Rows 
ORDER BY s.Name, t.Name 
GO

结果:
