Question

I’m trying to skip over calculating some numbers when the result would be an attempt to insert NaN into the DB. My code is as follows:

unless @X = 0 || @Y = 0 || Z= 0 #Don't execute below code if any of the three values = 0
    #Do some stuff with @X, @Y and @Z
end

I know that X,Y and Z are positive integers, as they should be, however this statement is not triggering the code block in the unless clause. Am I blatantly misusing the || operator?

Answer 1

You’re using = the assignment operator. You want to be using == the equality operator. Your code should look like this:

unless @X == 0 || @Y == 0 || @Z == 0
...
end
