Hi, Denodo provides a CASE clause, that provides an if-then-else type of logic. You can find all the information about this clause in section 5.12 of the Advanced VQL Guide ( Basically, you just need to edit your view, go to the Output tab, and click on the edit icon of the corresponding attribute (lets say date_to), or just add a new one, and type the following field expression: CASE WHEN (date_to < date_from) THEN date_from ELSE date_to END Hope this helps.
