SQL Server查看所有表大小，所佔空間

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 int,reserved int,data int,index_size int,unused int)  insert into #dataNew select name,convert(int,row) as row,convert(int,replace(reserved,'KB','')) as reserved,convert(int,replace(data,'KB','')) as data, convert(int,replace(index_size,'KB','')) as index_size,convert(int,replace(unused,'KB','')) as unused from #data   select * from #dataNew order by data desc    

--主要原理： 
exec sp_spaceused '表名' --取得表佔用空間 
exec sp_spaceused ''--數據庫所有空間 

還有一個簡單的辦法

SELECT   a.name, b.rowsFROM      sysobjects AS a INNER JOIN                 sysindexes AS b ON a.id = b.idWHERE   (a.type = 'u') AND (b.indid IN (0, 1))ORDER BY b.rows DESC
