Well, ZSQL Methods always return result sets, never strings.
The restult set is an object which works similar to a list
with result objects, each result object having attributes
which correspond to column names of your query.

The result objects have a method dictionaries() which in fact
return the data as regular list with dictionaries for the
rows (easier to look at if you see their string representation)

so what you probably want goes like this:

if result:
    userlevel=somedefault # or raise error or whatnot

the "if result:" idiom handles the fact the query might not
return any result. It is true however if you get at least one
row. result[0] addresses the very first row of the result
- which must exist in a non empty result set.
