Looking up values in two different tables

[jacques_412]

I need to lookup a value for each individual in a table. The problem is, some of the data is coming from an API which uses quite a complicated calculation to lookup the correct value, and the other data is coming from a simple csv file. These two files in no way overlap. Unfortuantely, the csv data cannot be uploaded to the API.

Is there some way I can achieve this?

Can you provide a snapshot example of a couple records of data in each of the 3 tables (and their relationships)?

- Table 1 (containing individual lookup value)

- Table 2 (from API)

- Table 3 (CSV)

Please also include a screenshot of your expected result for the given records.

You mentioned that the API & CSV tables do not overlap.

Does this mean you want logic that does the lookup first in the API table if it exists?

And if it does not exist there, then go & do the lookup in the CSV table?

Or am I misunderstanding?
