Overview

A literal standing where an expression would: select { value(0).as(:depth) }.

Values reach the SQL quoted wherever they appear as an operand, but the top of a select list is ActiveRecord's, and a bare string there is SQL rather than a string. Saying value is how you ask for the other meaning, and it carries the predications with it, so a literal can be compared and combined like anything else.
