执行下面的sql可以得到当前所在的数据库的数据文件所在的盘符的剩余空间（MB）

declare @drivename char(1)
select @drivename=left(filename,1) from sysfiles where fileid= 1

if not exists(select 1 from tempdb.dbo.sysobjects where name like '#FreeSpace%' and type='U')
create table #FreeSpace(
Drive char(1),
MB_Free int
)
else
truncate table #FreeSpace

insert into #FreeSpace
exec xp_fixeddrives

select MB_Free from #FreeSpace where Drive = @drivename
go
