本文介绍了一个SQL Server中用于查询表及整个数据库空间使用情况的方法。通过存储过程和游标实现遍历所有用户表并收集其占用空间的数据，最终将结果整理成易于阅读的格式。

--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
