Translate Ruby Script to SQL Query?

I need help translating a ruby script to SQL query. I’m a SQL noob. Help please.

[em]here is the script.[/em]

require “rubygems” require “ruport”

SQL = <<-EOS SELECT     tv.ApptDate, tv.PatName, tv.PatFirst, tv.PatLast, tv.Phone, tv.ApptTime, tv.Provlast, tv.ProvFirst, tv.ProvTitle, tv.Clinic, tv.Age, tv.Notes FROM (
