Aleksey Plekhanov updated CALCITE-7035:
---------------------------------------
Description:
After CALCITE-6978 {{SqlCall}}'s with subqueries are not rewritten during
validation even when {{withCallRewrite(true)}} property is set in the
configuration.
Functions like {{NULLIF}}, {{YEAR}}, {{MONTH}}, etc don't have implementor or
convertlet, so, when used with subqueries, throw an error: Unable to implement.
Examples of problematic queries:
{noformat}
select nullif((select max(emps.age) from emps), 0);
select year(select max(joinedat) from emps);
{noformat}
