sbroeder opened a new pull request, #5307: URL: https://github.com/apache/calcite/pull/5307
HsqldbSqlDialect inherited the default true behavior for supportsNestedAggregations(), so an aggregate over an expression of another aggregate was pushed down, which HSQLDB rejects. Report that HSQLDB does not support nested aggregations so that the converter generates a sub-SELECT, similar to how MySQL and PostgreSQL are already handled. ## Jira Link [CALCITE-7838](https://issues.apache.org/jira/browse/CALCITE-7838) -- This is an automated message from the Apache Git Service.
