I've created an SQLite geodatabase in ArcGIS Pro (2.7), added a text field for an attribute and then created a few polygons and filled in the attribute as a test. Works great.
I've been unable to edit those text attributes outside of ArcGIS Pro. I've tried using DB Browser for SQLite and I've tried linking to external data from within MS Access. ArcGIS Pro is closed when I've tried this.
The error message in DB Browser is "Error changing data: no such function: UpdateIndexEntry".
Does anyone know if SQLite attributes can be edited outside of ArcGIS Pro?
