------------------------------------
Summary: GenerateTableFetch - Add attributes to generated flow
files to ease SQL query overwrite
Key: NIFI-3596
URL: https://issues.apache.org/jira/browse/NIFI-3596
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Pierre Villard
Assignee: Pierre Villard
Priority: Trivial
The GenerateTableFetch processor will generate a SQL query based on the
provided parameters but, if the specific DB adapter is not available, it might
be necessary to overwrite the SQL query in the ExecuteSQL processor. To do that
it would be nice to have each part of the query as attributes to take advantage
of expression language.
Current workaround (when using GenerateTableFetch against a DB2 database for
example) is to have an intermediary ExtractText processor and have a regex
extracting each part of the generated query.
