Julian Hyde commented on CALCITE-2051: -------------------------------------- Is there a SQL query that illustrates this problem? > Rules using Aggregate might check for simple grouping sets incorrectly > ---------------------------------------------------------------------- > > Key: CALCITE-2051 > URL: https://issues.apache.org/jira/browse/CALCITE-2051 > Project: Calcite > Issue Type: Bug > Components: core > Reporter: Jesus Camacho Rodriguez > Assignee: Jesus Camacho Rodriguez > Priority: Critical > Fix For: 1.15.0 > > > CALCITE-1069 removed the indicator columns for Aggregate operators. In some > places, the indicator boolean check was replaced by the following check: > {{aggregate.getGroupSets().size() > 1}}. However, that check is incomplete, > it should have been replace by {{aggregate.getGroupType() == Group.SIMPLE}}. > For instance : > https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/rel/rules/AggregateProjectMergeRule.java#L91 -- This message was sent by Atlassian JIRA (v6.4.14#64029)
