Maryann Xue commented on PHOENIX-1580:
--------------------------------------
Agree with you on idea of treating all statements the same way, [~jamestaylor].
But I think the logic should be put int QueryCompiler.compile() and maybe
compileUnionQuery() can call QueryCompiler.compileSubquery() for each
statement, wrap the inner plans with UnionPlan. That way, we can handle all
kinds of statements (including joins, derived tables) without caring much of
what types they actually are.
> Support UNION ALL
