Subject [jira] [Created] (GEODE-7240) Prevent Usage of Aggregates within WHERE clause
Date Tue, 24 Sep 2019 21:08:00 GMT
Juan José Ramos Cassella created GEODE-7240:
-----------------------------------------------

             Summary: Prevent Usage of Aggregates within WHERE clause
                 Key: GEODE-7240
                 URL: https://issues.apache.org/jira/browse/GEODE-7240
             Project: Geode
          Issue Type: Bug
          Components: querying
            Reporter: Juan José Ramos Cassella


Aggregate functions shouldn't be allowed as part of the {{WHERE}} clause.
Currently, instead of rejecting the query, we throw a {{ClassCastException}} while trying
to evaluate the condition:

operator to compare an instance of class ' org.apache.geode.cache.query.internal.aggregate.XXX
