Qlik Script has a number of features designed to server the specialized requirements of Qlik Transformation and Dimensional Modeling. A few things that come to mind that are easy in Qlik but harder in SQL:
1. MAPPING. Whether data mapping or "RENAME FIELDS USING mapname" the Qlik solution is simple and elegant.
3. Qlik Script provides more Datetime functions than a typical SQL implementation. For example, "InYearToDate()".
