Inconsistent documentation of Table Conditional functions

Hi to all,
in the documentation of the Table Conditional functions [1] the example is
inconsistent with the related description (there's no resultX for example).
Or am I wrong?

Hi Flavio,

I believe the documentation meant "X" as a placeholder, where you can
convert "X" into the numeric values (1, 2, ...) depends on how many "CASE
WHEN" conditions you have.
*"resultZ" *is the default result in the "ELSE" statement, and thus it is a
literal.

Thanks,
Rong

Ok, thanks a lot for the clarification! Adding an "Example" on the right of
"Description" would be very helpful (IMHO)

Best,
Flavio

Hi Flavio,

In the description, resultX is just an identifier for the result of the first meeting condition.
