Hi! I’ve been taken a look at your query and there is an extra comma after *“… AS ROW_NUM”*. In addition, the *ROW_NUMBER* function is implemented as *ROWNUM* in the Denodo Platform and it doesn’t currently support *OVER* clause. I’d recommend you to check its syntax in the ROWNUM section of the [Advanced VQL Guide]( In this document you can also find all the information regarding VQL language syntax and functions. Hope this helps!

Hi! As I can confirm in the [Advanced VQL Guide](, *Rownum* function returns a unique number for each row of the result of a query. Therefore, it can only be used in the select clause of a query. Hope this helps!
