I bet the problem lies in the use of the CTOD() function, and the date1 and date2 are actually dates and not character strings.

Change the WHERE clause to this and see if it works:

WHERE Ventas.fechaonly BETWEEN ?date1 AND ?date2

>Following up with this question: what other methods, besides a view are there to get the same results?

The same SELECT statement without the "?" before the variables would probably be just fine in this case.
