Unconnected Lookup transformation

Unconnected Lookup transformation

You can configure an unconnected Lookup transformation for the Amazon Redshift source in a mapping. Use the Lookup transformation to retrieve data from Amazon Redshift based on a specified lookup condition.
An unconnected Lookup transformation is a Lookup transformation that is not connected to any source, target, or transformation in the pipeline.
An unconnected Lookup transformation receives input values from the result of a :LKP expression in another transformation. The Integration Service queries the lookup source based on the lookup ports and condition in the Lookup transformation and passes the returned value to the port that contains the :LKP expression. The :LKP expression can pass lookup results to an expression in another transformation.
For more information about the Lookup transformation, see
