Set to the name of the translator which is to be mimicked.
-
You can also use the Loopback translator to mimic how a real source query would be formed for a given translator (although loopback will still return dummy data that may not be useful for your situation). To enable this behavior, set the DelegateName property to the name of the translator you wish to mimic. For example to disable all capabilities, set the DelegateName property to "jdbc-simple".
A source connection is not required for this translator.
