Good point, will add them
> Allow SQL results to be output as records in any supported format

> Key: NIFI-4517
> URL: https://issues.apache.org/jira/browse/NIFI-4517
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Priority: Major
>
> ExecuteSQL and QueryDatabaseTable currently only outputs Avro, and the schema
> is only available as embedded within the flow file, not as an attribute such
> as record-aware processors can handle.
> ExecuteSQLÂ and QueryDatabaseTable processors should be updated with a
> RecordSetWriter implementation. This will allow output using any writer
> format (Avro, JSON, CSV, Free-form text, etc.), as well as all the other
> features therein (such as writing the schema to an attribute, and will avoid
> the need for a ConvertAvroToXYZ or ConvertRecord processor downstream.
