使用如下sql script可以获得每个数据库表所占用的空间大小，单位是KB

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

drop table #Data
drop table #dataNew
