:as => :column

[snarglebritchet]

Please add a new :as type called :column which

1. yields each row as a single item, which may be nil, or returns all items as a flat array
2. complains if the number of returned columns is >1

It's equivalent to :as => :array and then using row[0], but avoids building garbage arrays.

Not a bad idea. I might try and hack on this soon.
