----------------------------------------------
Summary: Subquery inside case when clause -
ConcurrentModificationException is thrown
Key: ASTERIXDB-1581
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1581
Project: Apache AsterixDB
Issue Type: Bug
Environment: Master branch with latest commit id:
bd3a535b171a5cc7486175
Reporter: Vignesh Raghunathan
To reproduce the issue run the following sqlpp query after creating the types
and datasets in the attached file tpcdsadb:
{code}
select case when (select value count(ss)
from store_sales ss
where ss_quantity >= 1 and ss_quantity <= 20) > 25437
then (select avg(ss_ext_discount_amt)
from store_sales
where ss_quantity >= 1 and ss_quantity <= 20)
else (select avg(ss_net_profit)
from store_sales
where ss_quantity >= 1 and ss_quantity <= 20) end bucket1
from reason
where r_reason_sk = 1;
{code}
Result:
{code}
