Julian Hyde commented on CALCITE-5455:
--------------------------------------
Probably not a large enough change to warrant a reviewer's time. If I were you
I would batch up a few changes that add tests to big-query.iq and submit them
as one PR; or combine this change with a PR that implements one or more
functions.
Before you logging a bug, here's a quick way to check whether a function is
implemented in Calcite:
{code}
$ cd calcite
$ git ls-files | xargs grep -in nullif
{code}
> Add Quidem tests for NULLIF()
