Where do I find the code that creates the concept_ancestor table


(Kieran Mace) #1

Hi there, from the documentation about the concept_ancestor table:

This table is entirely derived from the CONCEPT, CONCEPT_RELATIONSHIP and RELATIONSHIP tables.

(https://github.com/OHDSI/CommonDataModel/wiki/CONCEPT_ANCESTOR)

Is there somewhere I can find that code? I’m trying to figure out why my results are different when traversing the concept_relationship dag, and using the ancestor table directly.

Probably not a lot of fun reverse engineering this. What’s the difference you are finding?
