SQL and Tableau both support a CASE function with the syntax
WHEN Condition 1 THEN Result 1
WHEN Condition 2 THEN Result 2 ...
WHEN Condition N THEN Result N
ELSE Default Result
I'm thrilled that I can now use this with the In-DB tools, but I'd love to have this available in the regular function tools so I can stop nesting my IFs!
In an Alteryx function one option somewhat equivalent to this is a Switch
But the downside is that rather than full flexibility on your conditions, you are always comparing against the Value. So each condition is Value==Case1; Value==Case2... etc.
And you say you are nesting your IFs. Did you know about ELSEIF? Which can give a very similar syntax to the SQL CASE
IF Condition 1 THEN Result 1
ELSEIF Condition 2 THEN Result 2...
ELSEIF Condition N THEN Result N
Wait that works now? Yay! In 9.5 I always got error mesages when I tried to use more than one ELSEIF without nesting, and I assumed based on the syntax description that the error was because you were only allowed one ELSEIF. (It was probably some other user error though.)
Can you change the description for this to "IF c THEN t ELSEIF c2 THEN t2 ... ELSEIF cN THEN tN ELSE f ENDIF" or something else that conveys the joys of unlimited ELSEIFs?
Ran across this post trying to tackle a something similar. It looks like (in v10.6~) you can use a switch function like you would case statement by setting the value to boolean true. In my case, I was using the Contains function that returned -1 for true (which is the weirdest boolean "true" value I've ever seen):
