扩展 xp_fixeddrives

 

xp_fixeddrvies提供磁盘分区的信息太少，如下的脚本提供磁盘分区的使用情况，运行需要管理员权限！

if not exists( select * from sys.configurations(nolock) cc 
 where cc.name='xp_cmdshell' 
 and cc.value_in_use=1)

    reconfigure

    exec sp_configure 'xp_cmdshell',1
    reconfigure

drop table #fixeddrives_temp;
Go


if OBJECT_ID('tempdb..#totaldrives_temp') is not null
