Inconsistent documentation of Table Conditional functions

[Flavio Pompermaier]

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

Hi Flavio,

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

Best,

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

Best,

Flavio
