Andrus, you deserve a medal.
Everything works better than I could have hoped!
Thank you so much,

So you are casting the result to something else. Cast it to map:
List results = context.performQuery(....);
Iterator it = results.iterator();
while(it.hasNext()) {
Map result = (Map) it.next();
/// do something...
}
It recieved the correct number of rows (34), but when I try to access
them, I get errors. I've tried using an arbitrary class, and creating
a model in cayenne especially for the "show table status" table, with
attributes "Data_length" etc, so I have the correct getters and
setters, but no luck...
Is there a way to extract generic data form an undefined "Map"?
Yes - keys in the map are the column names from the ResultSet returned
from MySQL. The simplest way to see what keys are valid is this:
System.out.println("Keys: " + result.keySet());
So you can form instance use (but consult the output of the statement
above for the correct key values)
Number x = (Number) result.get("Data_length");
