Conditional lookup for two sources

JorgeVazquez

Hi Community,

I wonder if you can help me with something.

 

I am working on a large workflow. I am trying to join to different tables (sources) BUT with a conditional join.

As an example, please look at the tables below. "Table 1" contains the value I want to compare, and the "Table 2" contains the value I want to bring into my data. In this case, for instance, for my value "5", the corresponding joined value should be "A", for "7",  "9" and "11", should be "B", and so on. As you can see, I need to compare my value in Table 1 with the lower and higher limits in Table 2, to bring the value that matches.

11 1924D

Do you have any clues about how can I do this in Aleteryx?

 

I am using In-DB in the most of the cases, so if there is a solution with In-DB tools would be much better, if not that is not a problem.

 

Thank you very much in advanced.

The simplest way I can think of in this case (assuming it is integer values) is to use a Generate Rows tool to expand Table 2.

 

You can then join easily.

Thanks @jdunkerley79,

 

This is great.

 

In my case it is dates what I am trying to compare. Any clue on how could that work using dates?

 

Thanks!

You can use the datetimeadd function to increment. I am not in front of
Alteryx at the moment but will post a sample when I can.

How about something like the attached?
