Maryann Xue commented on PHOENIX-3355:
--------------------------------------
[~lomoree], PHOENIX-3466 is in now. You can use
PhoenixImplementor.getStatementContext() in CalciteUtils for function
expression instantiation. Still I found that CurrentDateFunction does not have
any arguments but do need a statement context to get the current timestamp. So
the default value solution may simply be not enough. Please do follow
[~jamestaylor]'s suggestion about checking for all {{nodeClass}} parameters in
the {{@BuiltInFunction}} annotations. That way you can see all places where
StatementContext is needed.
