Any better, more idiomatic way to convert SQL ResultSet to a Scala List or other collection type?

Why don't you try this:

new Iterator[String] {
  def hasNext = resultSet.next()
  def next() = resultSet.getString(1)
}.toStream

Taken from this answer here

I have a similar problem and my solution is:

Iterator.from(0).takeWhile(_ => rs.next()).map(_ => rs.getString(1)).toList

Hope that will help.
