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 a bare Ruby literal at the top of a select list is refused as saying nothing. value is the spelling that quotes it there, and it carries the predications with it, so a literal can be compared and combined like anything else.
