I'm new to Apex, so would appreciate some advice. We are using Apex 5 on Oracle 12c.
I have developed an interactive report against a table which contains 650 million rows. I would like to ensure that the user enters some sort of filter on the report, since attempting to run an unfiltered report will inevitable cause a crash due to the sheer volume of data returned.
Is there some way I can check that the user has set at least one filter on the report before running it, giving them an error message if they haven't?
