I've been through 3 domain name registrars and haven't really liked any of them, I've tried godaddy, enom, and gandi respectively. Though godaddy was a long time ago and I'd be willing to give them another shot given the right feedback.

I actually looked around for a few minutes thinking it would be a sinch to find a new one, but I always found some reason not to go with them. So I made a list and it turns out I have quite a few factors that influence my choice for a DNS registrar.

1. NS Glue Records / Delegation (Use own DNS servers)
2. Registration Price
3. Reseller Program / API

I recently had the opportunity to employ the use of some MS SQL stored procedures in a perl script I was working on in Freebsd. I'd gotten connections to MS SQL working from the perl script through the use of freetds and the DBI module. The stored procedures were only another step, getting the parameters to go was a little trickier but all in all it wasn't too bad. And since you're so interested the gist of it is:

$sth = $dbh->prepare(qq{exec Tester \@test='$var1', \@test2='$var2'});

with Tester being the name of the stored procedue and $var1 and $var2 being the arguments to the stored procedure. Then $sth->execute() of course.
