Vladimir Sitnikov commented on CALCITE-2535:
--------------------------------------------
Oh, I think I know an example:
{code:sql}select coalesce(case when count(*)>0 then 1 else null end, 0/0) from
values(1){code}
Not sure what to put instead of ..., but the idea is as follows: during
regular execution, 0/0 will never be reached.
However constant-folder might be too eager to constant-fold "0/0" computation
making the SQL to fail.
