SQL Server查看所有表大小，所占空间

--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 

 

 

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
