[jira] [Created] (SPARK-28553) subqueries always must be aggregated before

Dylan Guedes created SPARK-28553:
------------------------------------

             Summary: subqueries always must be aggregated before
                 Key: SPARK-28553
                 URL: https://issues.apache.org/jira/browse/SPARK-28553
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Dylan Guedes


Looks like Spark subqueries does not work well with variables and values from outside of subquery. For instance, this query work on PgSQL:
 {code:sql}
-- SELECT lead(ten, (SELECT two FROM tenk1 WHERE s.unique2 = unique2)) OVER (PARTITION BY four ORDER BY ten)                                                  -- FROM tenk1 s WHERE unique2 < 10;{code}
However, it does not work in Spark.
