adding records through linux shell?

I want to add a subdomain by running a script from the shell. I'm using this:
`mysql -uroot -pPassHere -e 'use powerdns; insert into records (domain_id, name, type, content, ttl, prio, change_date) values (2, "testsub.domain.com", "CNAME", "domain.com", 3600, 0, 1244667637);'`. Will this give the same exact result as if I went to the control panel and added the record manually? I checked all the tables and there seem to be no other values of the new subdomain if I add it manually in any other tables except for "records" but for some reason I am still unable to ping the new subdomain =/ Thanks!
