Ran Tao updated CALCITE-6063:
-----------------------------
Description:
calcite support array query constructor.
but If we run sub-query with orderby:
{code:java}
select array(select x from unnest(array[1,2,3]) as t(x) order by x desc);
select array(select x from unnest(array[1,2,3]) as t(x) order by x asc); {code}
they both return
{code:java}
+-----------+
| EXPR$0 |
+-----------+
| [1, 2, 3] |
+-----------+
{code}
however, we expect return *[3, 2, 1]* when use {*}order by x desc{*}.
It seems that the *order by* not works properly in array sub-query.
This issue is introduced by the issue
https://issues.apache.org/jira/browse/CALCITE-2978
However the ARRAY is not applicable in this scenario.
we also have another issue broke it.
