使用了微软提供的不公开的存储过程sp_MSforeachtable
 

CREATE TABLE #temp
(
 TableName NVARCHAR (128),
  RowsCnt VARCHAR (11),
 ReservedSpace VARCHAR(18),
 DataSpace VARCHAR(18),
 CombinedIndexSpace VARCHAR(18),
 UnusedSpace VARCHAR(18)
 )
 
 EXEC sp_MSforeachtable'INSERT INTO #temp (TableName, RowsCnt, ReservedSpace,DataSpace, CombinedIndexSpace, UnusedSpace) EXEC sp_spaceused ''?'', FALSE'
 
SELECT TableName, RowsCnt,ReservedSpace, DataSpace, CombinedIndexSpace, UnusedSpace
 FROM #temp
 ORDER BY TableName
 
DROP TABLE #temp
