Philipp Korniets updated NIFI-11671:
------------------------------------
Description:
We use ForkEnrichement - JoinEnrichment pattern and want to include filtering
in join SQL. Filter value is coming from FlowFile attribute
{code:sql}
${test} = 'NewValue'
SELECT original.*, enrichment.*,'${test}'
FROM original
LEFT OUTER JOIN enrichment
ON original.Underlying = enrichment.Underlying
WHERE enrichment.MyField = '${test}'
{code}
However this doesnt work because JoinEnrichment doesnt use
evaluateAttributeExpressions
