> Key: CALCITE-7837
> URL: https://issues.apache.org/jira/browse/CALCITE-7837
> Project: Calcite
> Issue Type: Bug
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Labels: pull-request-available
>
> {{{}ARRAY_MIN{}}}, {{{}ARRAY_MAX{}}}, and {{SORT_ARRAY}} fail for arrays of
> {{ROW}} values, including nested rows.
> Example:
> {code:java}
> SELECT ARRAY_MAX(ARRAY[ROW(1, 'Foo'), ROW(2, 'Bar')]);{code}
>
> Expected: ROW(2, 'Bar').
> Actual:
> {{ClassCastException: class [Ljava.lang.Object; cannot be cast to class
> java.lang.Comparable}}
> These functions require Java {{Comparable}} elements, but {{ROW}} values are
> represented as {{{}Object[]{}}}.
