Nattavut Sutyanyong commented on SPARK-18863:
---------------------------------------------
My further investigation concludes this problem reported by [~smilegator] is
different from the one in SPARK-16161 and the one reported by me in
subquery/in-subquery/in-group-by.sql TC 01.12. I have opened SPARK-19047 to
track the last problem.
> Output non-aggregate expressions without GROUP BY in a subquery does not
> yield an error

> Key: SPARK-18863
> URL: https://issues.apache.org/jira/browse/SPARK-18863
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Nattavut Sutyanyong
>
> [~smilegator] has found that the following query does not raise a syntax
> error (note the GROUP BY clause is commented out):
> {code:sql}
> SELECT pk, cv
> FROM p, c
> WHERE p.pk = c.ck
> AND c.cv = (SELECT max(avg)
> FROM (SELECT c1.cv, avg(c1.cv) avg
> FROM c c1
> WHERE c1.ck = p.pk
> -- GROUP BY c1.cv
> ))
> {code}
> There could be multiple values of {{c1.cv}} for each value of {{avg(c1.cv)}}.
