Join stage: fast path

Join stage: fast path (DataStage)

This section specifies the minimum steps to take to get a Join stage functioning.

To use a Join stage:

  • On the Stage tab in the stage editor, use the Properties section to specify the key column or columns that the join will be performed on. Specify the join type or accept the default of Inner.
  • In the Link Ordering section, check that your links are correctly identified as "left", "right", and "intermediate" and reorder if required.
  • Ensure required column metadata has been specified (this might be done in another stage).
  • On the Output tab, select Edit in the Columns section. Here, you can specify how the output columns are derived, that is, what input columns map onto them or how they are generated in the Maps from input column section.
