Sequel::SQL::BooleanMethods

This module includes the boolean/logical AND (&), OR (|) and NOT (~) operators that are defined on objects that can be used in a boolean context in SQL (Symbol, LiteralString, and SQL::GenericExpression).

  :a & :b # "a" AND "b"
  :a | :b # "a" OR "b"
  ~:a # NOT "a"

One exception to this is when a NumericExpression or Integer is the argument to & or |, in which case a bitwise method will be used:

  :a & 1 # "a" & 1 
  :a | (:b + 1) # "a" | ("b" + 1)
