保存数据的表


create table dc_DiskDetaill 
(
 Drive varchar(10),
 Size  varchar(50),

 GetTime  datetime default(getdate())
)

  drop table #all2 
 EXEC sp_configure 'show advanced options', 1
RECONFIGURE
EXEC sp_configure 'xp_cmdshell', 0
RECONFIGURE
EXEC sp_configure 'show advanced options', 0
RECONFIGURE


 drop table #freedisk
end

调用存储过程并查看是否有数据
exec [Usp_Get_DiskSize]


select * from  dc_DiskDetaill
