ELT Sort

Overview

Use this Snap to add the ORDER BY keyword to an existing query. The ORDER BY keyword enables you to sort records in ascending or descending order of a specified column's value. Additionally, the Snap also enables you to specify whether null value records are displayed first or last. This Snap also allows you to preview the result of the output query. You can validate the modified query using this preview functionality.
