I have a CSV-file with "ID"s. I would like to identify a feature in my database table that matches those "ID"s.

How can I use a tester/feature merger or something similar to get the records I am looking for?

Several solutions possible. One is:

  1. Read the csv with the id's
  2. Then read the database with a FeatureReader.
    • Fill the Where Clause to only read the matching features. (Otherwise you need to read all the records from the database and the power of a database is you can query it.)
    • Merge Initiator attributes with result, prefix initiators to prevent corresponding attributenames to overwrite each other.
