union_all($select :SQL::Maker::Select | $set :SQL::Maker::SelectSet) : SQL::Maker::SelectSet Tow statements are combined by UNION ALL.
intersect($select :SQL::Maker::Select | $set :SQL::Maker::SelectSet) : SQL::Maker::SelectSet Tow statements are combined by INTERSECT.
intersect_all($select :SQL::Maker::Select | $set :SQL::Maker::SelectSet) : SQL::Maker::SelectSet Tow statements are combined by INTERSECT ALL.
except($select :SQL::Maker::Select | $set :SQL::Maker::SelectSet) : SQL::Maker::SelectSet Tow statements are combined by EXCEPT.
except($select :SQL::Maker::Select | $set :SQL::Maker::SelectSet) : SQL::Maker::SelectSet Tow statements are combined by EXCEPT ALL.

Class Method

my $stmt = SQL::Maker::SelectSet->new( %args ) $opretaor is a set operator (ex. UNION). $one and $another are SQL::Maker::Select object or SQL::Maker::SelectSet object. It returns a SQL::Maker::SelectSet object.
