Hello,
I have two columns Category and Class already filled. I would like to compare and see if the class entered is in the right category.
Example :
Category = 10 / Class = 20, 40, 60
Category = 11 / Class = 20, 21, 22, 23, 24
Category = 12 / Class = 23, 25, 27, 29, 31
Category
Class
RESULT
10
20
True
10
22
False
11
23
True
12
23
True
10
29
False
12
31
True
10
60
True
Thank you very much in advance for your help.
Best Regards

Hi,
There are a number of possibilities, just had @david_r mentions.
I would use an AttributeCreator and conditional values:
Probably can be fancied up by some regex....
One possible solution would be to use an AttributeValueMapper to calculate the correct class based on the category value, then a Tester to compare the correct class with the existing class value.

Thank you very much for your answer.
Could you be more specific please?
The problem is that each category has multiple class value and sometimes one class value could be in different categories.

It works, thank you very much for your answer
I would create an external table mapping each Category and comma-separated possible classes like this,
CategoryPossibleClasses1020,40,601120,21,22,23,241223,25,27,29,31merge an appropriate possible classes to each record using a DatabaseJointer or a FeatureMerger, and then determine if the class is in the possible classes with conditional value setting.

Depends on what you consider to be the correct Category for Class = 20? Are both values 10 and 11 correct?

This the approach i would take, for ease of maintenance. Although i'm getting an odd result with the In Test
You could also use an AttributeValueMapper to add the possible class values, then do the test. Might be a better option than a FeatureMerger if it the values aren't changing.

Hi @egomm, I was able to reproduce the odd behavior. I suspect that there is a potential bug regarding the IN operator, Comparison Mode, or somewhere. I reported the issue to Safe support already, and they filed a problem report.
In the interim, you can get correct result if you set a string mode (Case Sensitive or Case Insensitive) to the Comparison Mode parameter in the Tester.
