------------------------------------------

             Summary: Some SQL calls (NULLIF, YEAR, ...) with subquery as 
parameter throws an error
                 Key: CALCITE-7035
                 URL: https://issues.apache.org/jira/browse/CALCITE-7035
             Project: Calcite
          Issue Type: Bug
    Affects Versions: 1.40.0
            Reporter: Aleksey Plekhanov


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 queies:
{noformat}
select nullif((select max(emps.age) from emps), 0);
select year(select max(joinedat) from emps);
{noformat}
