xiong duan commented on CALCITE-7056:
-------------------------------------
Please verify your idea based on the test cases.
The situations I can currently think of mainly include:
{code:java}
1)Sub-query: select * from public.salgrade where grade >some (select grade from
public.salgrade);
2)ArrayValueConstructor: 1.0 = some (ARRAY[2,3,null])
3)Column Reference: WITH tb as (select array(SELECT * FROM (VALUES ('1970-01-01
01:23:45'), ('1970-01-01 01:23:46')) as x(a)) as a) SELECT timestamp
'1970-01-01 01:23:45' >= some (a) FROM t
4)Values: SELECT 1.0 = SOME (VALUES (1.0), (2.0));{code}
Perhaps some of the test cases have already been covered.
