[teiid-issues] [JBoss JIRA] (TEIID-1993) Pushdown GROUP BY as DISTINCT when data source does not support inline views

[ https://issues.jboss.org/browse/TEIID-1993?page=com.atlassian.jira.plugin... ] Steven Hawkins updated TEIID-1993: ---------------------------------- Fix Version/s: 8.1 Priority: Minor (was: Major) For non-union views (which will require inline view support) you can workaround by marking the translator as supporting GROUP BY, but no aggregate functions nor the having clause. However the translator will still be responsible for ensuring that if GROUP BY is used instead of distinct, that the selected columns match the grouping columns or that an appropriate subset of the distinct is projected. For the case at hand, we need to detect the equvalence with distinct prior to view removal, then the union will be appropriately changed from a UNION ALL to a UNION to account for the DISTINCT operation. -- This message is automatically generated by JIRA.
