Public Instance Methods

asc(opts={}) click to toggle source

Mark the receiving SQL column as sorting in an ascending fashion (generally a no-op). Options:

:nulls

Set to :first to use NULLS FIRST (so NULL values are ordered before other values), or :last to use NULLS LAST (so NULL values are ordered after other values).

     # File lib/sequel/sql.rb, line 759
759:       def asc(opts={})
760:         OrderedExpression.new(self, false, opts)
761:       end
desc(opts={}) click to toggle source

Mark the receiving SQL column as sorting in a descending fashion. Options:

:nulls

Set to :first to use NULLS FIRST (so NULL values are ordered before other values), or :last to use NULLS LAST (so NULL values are ordered after other values).

     # File lib/sequel/sql.rb, line 769
769:       def desc(opts={})
770:         OrderedExpression.new(self, true, opts)
771:       end
