----------------------------------
Status: Patch Available (was: Open)
> Allow ExecuteSQL to not overwrite flowfile content when no result
> -----------------------------------------------------------------
>
> Key: NIFI-14266
> URL: https://issues.apache.org/jira/browse/NIFI-14266
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Pierre Villard
> Assignee: Pierre Villard
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The ExecuteSQL processor may be used in a flow definition to execute SQL
> statements such as TRUNCATE TABLE, DROP TABLE, etc. While there is the option
> to use pre/post queries, it might not always be an option to have everything
> executed within the same processor. In such a scenario, it might be needed to
> not change the content of the FlowFile.
> This improvement adds a property allowing a user to specify that the
> FlowFile's content should remain untouched when the execution of the query
> does not generate any result and, of course, when the processor was triggered
> by an incoming FlowFile.
