Use custom data

I have a custom data set I’ve uploaded - how do I use this in a schema? It’s in the same project - but I can’t seem to use it.

All you need to do is add a column with the Type set to Dataset Column.
Example:

If you want to derive a column fields value based on that dataset you would need to use a Formula Type and then use this formula:

from_dataset(“dataset”, “column”, join_criteria) => Fetches a value from a dataset.
For example, from_dataset(“People”, “name”, id: person_id) returns the value of the “name” column from the “People” dataset where the id column matches the person_id column in the current schema.
