Parameterized views

[Elliot West]

Hello,

Does any version of Hive support parameterized views. I'm thinking of
something like the following contrived example:

CREATE VIEW x AS
  SELECT a
  FROM y
  WHERE date = ${mydate}


I've not been able to get this to work in Hive 1.2.1 or 2.1.0 and wonder if
this is the intended behavior, or I'm not constructing the view correctly.

Is it perhaps better instead to push up the filter columns to the view so
that they are accessible to the caller there?:

CREATE VIEW x AS
  SELECT a, date
  FROM y


Would this have any limitations in comparison with the variable
substitution approach?

Thanks,

Elliot.
