Julian Hyde commented on CALCITE-4505:
--------------------------------------
Is there a better, more minimal test case? {{IF}} is not enabled by default,
but it seems that your problem is with {{IN}}, so {{IF}} just confuses the
matter.
Does {{COUNT(id IN (1, 2))}} work?
> SqlToRelConverter should support converting 'in condition clause' in 'agg
> function' such as 'count(if(id in (1), 1, null))' to rel expression by default
