Remove Zero Event Host

[ITSD]

I'd already use "| delete" try to delete host, but it still remain there with event count 0. How could I remove no more need event source?

[ITSD]

I'd use | metadata type=hosts index=main | convert ctime(recentTime) as Recent_Time | where lastTime < (now() -3600)

to check no events host every hour, but get this result 12/16/2010 17:23:01 9223372036854775807 xxx.xx.xx.xx 0 1292491381 0 hosts

I'd remove xxx.xx.xx.xx with | delete but still show there how could I fix it?

Thanks
