Query validation helps identify problems, before running a query. Validation is automatically invoked as you edit your query or you can choose to execute it from the toolbar. It also checks each task for the following potential problems:
Example:
When you add a Summarization step after a File step, the Key Selection tasks will initially be displayed with a red X. The X indicates that you must visit the task and verify that the default key selections are appropriate for your query.
Clicking Validate on the toolbar clears the red Xs for tasks that need verification; however, we recommend that you check each task to verify the current selections.
Example:
When you load an existing query that contains elements that are no longer valid, the associated element selection task is marked with a red X. The X indicates that you must visit the task and remove or replace the invalid elements.
Correcting all the errors within the task, clears the red X. Clicking Validate on the toolbar now will not clear a red X that indicates an error.
Note: Validation does not prevent you from running or saving a query. Even if a query has validation errors it can still be run and saved.
