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
