----------------------------------
Resolution: Done
> Use separate merge query when there are no delete or update cases listed
> ------------------------------------------------------------------------
>
> Key: IMPALA-13205
> URL: https://issues.apache.org/jira/browse/IMPALA-13205
> Project: IMPALA
> Issue Type: Sub-task
> Reporter: Peter Rozsa
> Assignee: Peter Rozsa
> Priority: Minor
> Labels: impala-iceberg
>
> If a MERGE statement lists no WHEN MATCHED THEN DELETE or WHEN MATCHED THEN
> UPDATE clause, the merge query should not contain the position values of the
> target table. It should be handled in analyze time and requires a different
> evaluation at the Iceberg Merge node at the execution layer.
