I am trying to write a ruby script that will parse a tab-delimited text file
and load the data into a database table.  Here is my script:

require "dbi"

DBI.connect("DBI:OCI8:mydb", "myusername", "mypassowrd") do |dbh|
  sth  bh.prepare("INSERT INTO my_table VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?,
?, ?, ?, ?, ?, ?, ?, ?, ?, ?)")

  f  ile.open("data.txt", "r")
  id  
  f.each_line do |line|
    values  id]
    values.concat line.chomp.split("\t")
    (10..12).each {|x| values[x]  ime.parse(values[x]) unless
values[x].nil? || values[x].strip ""}
    sth.execute(values)
    id + 
  end

end

Unfortunately, when it executes, I get this:

c:/ruby/ruby-1.8.4_16/lib/ruby/site_ruby/1.8/oci8.rb:664:in `bindByPos': Not
supported type (Array) (ArgumentError)
        from c:/ruby/ruby-1.8.4_16/lib/ruby/site_ruby/1.8/oci8.rb:664:in`bind_or_define'

        from load_from_txt.rb:8
        from c:/ruby/ruby-1.8.4_16/lib/ruby/site_ruby/1.8/dbi/dbi.rb:590:in`connect'

        from load_from_txt.rb:3

I think the problem is that the execute method expects a varargs, but it is
getting an Array.  How do I convert the Array into varargs?
