EmulateOuterJoins

class EmulateOuterJoins extends Phase

An optional phase which rewrites outer joins into more commonly supported operations for use on databases that lack outer join support.

Full outer joins are always emulated. Right joins can be replaced by left joins (or an emulated version thereof). Left joins can be emulated with inner joins and unions.
