Delete Computer ID from Database

Hi I am looking for an sql query that I can run through a script from DS6.9 when imaging a computer to remove it from the Symantec_cmdb database. I am looking for the same as going to Manage - Computers - delete. We are currently using NS Version 7.1.8400.

I think I would need to search on the serial number of the computer, as the name and/or Ip may change.

this is to eliminate computers getting previously deployed applications.

Thanks in advance, Cat
