Show Suggested Answer

Suggested Answer: C

When a field name in an existing Custom Data Type (CDT) needs to be changed to match a renamed database field, and the Automatically Update Database Schema option is disabled, the correct approach is to rename the field in the CDT within Appian. After renaming the field in the CDT to match the new database column name (from BIRTHDATE to DATE_OF_BIRTH in this case), you should verify the changes and publish the data store to reflect the updates. This approach ensures that the Appian data model remains in sync with the underlying database schema. Reference: Appian Documentation - Data Types and Data Stores

Hmm, this seems tricky since the database schema auto-update is disabled. I think C might be the way to go, but I'd want to verify that it updates the backend properly.
