amaliujia edited a comment on issue #1636: [CALCITE-3568] BigQuery, Hive, Spark SQL dialects do not explicitly support nested aggregates URL: https://github.com/apache/calcite/pull/1636#issuecomment-565749188 (will also add the following to JIRA) I also verified Spark SQL does not support nested aggregations ``` spark-sql> SELECT sum(count(key)) FROM (select 1 AS key); Error in query: It is not allowed to use an aggregate function in the argument of another aggregate function. Please use the inner aggregate function in a sub-query.;; Aggregate [sum(count(key#0)) AS sum(count(key))#3L] +- SubqueryAlias `__auto_generated_subquery_name` +- Project [1 AS key#0] +- OneRowRelation ``` I don't have access to Hive so that's the left part to be verified.
