Treating an SQL ResultSet like a Scala Stream

Question

When I query a database and receive a (forward-only, read-only) ResultSet back, the ResultSet acts like a list of database rows.

I am trying to find some way to trea

Answer 1

I think most of above implementations has a nondeterministic hasNext method. Calling it two times will move cursor to the second row. I would advise to use something like that:

  new Iterator[ResultSet] {
    def hasNext = {
      !resultSet.isLast
    }
    def next() = {
      resultSet.next()
      resultSet
    }
  }
