Selecting the columns of interest

About this task

The schema of tRuleSurvivorship includes several technical columns like GID, GRP_SIZE, which are not interesting in this example, so you may need to use tFilterColumns to rule these technical columns out and leave the columns carrying actual data to be output. To do this, proceed as follows:

Procedure

  1. Double-click tFilterColumns to open its Component view.
  2. Click Sync columns to retrieve the schema from its preceding component. If a dialog box pops up to prompt the propagation, click Yes to accept it.
  3. Click the [...] button next to Edit schema to open the schema editor.
  4. On the tFilterColumns side of this editor, select the GID, GRP_SIZE, MASTER and SCORE columns and click the red cross icon below to remove them.
  5. Click OK to validate these changes and accept the propagation prompted by the pop-up dialog box.
