SQL Server查看所有表大小，所占空间

create table #Data(name varchar(100),row varchar(100),reserved varchar(100),data varchar(100),index_size varchar(100),unused varchar(100))    declare @name varchar(100)  declare cur cursor  for      select name from sysobjects where xtype='u' order by name  open cur  fetch next from cur into @name  while @@fetch_status=0  begin      insert into #data      exec sp_spaceused   @name      print @name        fetch next from cur into @name  end  close cur  deallocate cur    create table #DataNew(name varchar(100),row BIGINT,reserved BIGINT,data BIGINT,index_size BIGINT,unused BIGINT)    insert into #dataNew  select name,convert(BIGINT,row) as row,convert(BIGINT,replace(reserved,'KB','')) as reserved,convert(BIGINT,replace(data,'KB','')) as data,  convert(BIGINT,replace(index_size,'KB','')) as index_size,convert(BIGINT,replace(unused,'KB','')) as unused from #data     select * from #dataNew order by data desc     DROP TABLE #Data DROP TABLE #dataNew
 

--主要原理： 
exec sp_spaceused '表名' --取得表占用空間 
exec sp_spaceused ''--數據庫所有空間 
还有一个简单的办法
SELECT   a.name, b.rows
FROM      sysobjects AS a INNER JOIN
                 sysindexes AS b ON a.id = b.id
WHERE   (a.type = 'u') AND (b.indid IN (0, 1))
ORDER BY b.rows DESC
