--------------------------------------

             Summary: Having clause does not work with explode anymore
                 Key: SPARK-26270
                 URL: https://issues.apache.org/jira/browse/SPARK-26270
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Olli Kuonanoja


Hi,

In Spark 2.3.0 it was possible to execute queries like
{code:sql}
select explode(col1) as v from values array(1,2) having v>1
{code}
but in 2.4.0 it leads to 
{noformat}
org.apache.spark.sql.AnalysisException: Generators are not supported outside the SELECT clause, but got: 'Aggregate [explode(col1#1) AS v#0];
{noformat}

Before looking into a fix I'm trying to understand if this has been changed on purpose and if there is an alternate construct available. Could not find any pre-existing tests for the explode-having combination.
