I am looking for a query browser that would let me run queries that I have written on a schedule and export the results to a CSV. Does Valentina Studio allow me to do this?
No, there's no such exact functionality, if you are interested only in CSV export.
However, there is an option for other formats, using Valentina Server and Valentina Studio Pro.
It is possible:
1. To generate report on schedule
2. Print it to PDF or HTML
3. Send by email
I think saving PDF to disk can be very easy to implement, if interested.
