[jira] [Created] (IMPALA-11779) Codegen crash due to null slots
Quanlong Huang created IMPALA-11779:
---------------------------------------
Summary: Codegen crash due to null slots
Key: IMPALA-11779
URL: https://issues.apache.org/jira/browse/IMPALA-11779
Project: IMPALA
Issue Type: Bug
Reporter: Quanlong Huang
Assignee: Quanlong Huang
Simple repro:
{code:sql}
create table if not exists tbl (id int);
with v1 as (
select '0' as a1, '' as b1 from tbl
), v2 as (
select '' as a2, null as b2
), v3 as (
select b1 as b
from v1 left join v2 on a1 = a2
)
select 1 from (
select row_number() over (partition by b order by b) rnk
from v3
) v
where rnk = 1;
{code}
