## Quick question. If I create my DB outside of NC, how can I tell NC that a specific text column should be treated as an Attachment Type? Is this even possible or can it only be done with the NC UI? I’m using SQLAlchemy BTW.

#### reubano@discord Only way possible right now is to change column type to ‘Attachment’ after project is created. Let us know if that helps.

#### If you do schema changes from outside, you would have to first sync the changes of schema to nocodb
