Module Sequel::SQL::OperatorBuilders
In: lib/sequel/sql.rb

This adds methods to create SQL expressions using operators:

  Sequel.+(1, :a)   # (1 + a)
  Sequel.-(1, :a)   # (1 - a)
  Sequel.*(1, :a)   # (1 * a)
  Sequel./(1, :a)   # (1 / a)
  Sequel.&(:b, :a)   # (b AND a)
  Sequel.|(:b, :a)   # (b OR a)

Public Instance methods

Return NumericExpression for the exponentiation:

  Sequel.**(2, 3) # SQL: power(2, 3)

849:       def **(a, b)
850:         SQL::NumericExpression.new(:**, a, b)
851:       end

Invert the given expression. Returns a Sequel::SQL::BooleanExpression created from this argument, not matching all of the conditions.

  Sequel.~(nil) # SQL: NOT NULL
  Sequel.~([[:a, true]]) # SQL: a IS NOT TRUE
  Sequel.~([[:a, 1], [:b, [2, 3]]]) # SQL: a != 1 OR b NOT IN (2, 3)
