Question #: 27
Topic #: 6

Your customer wants to change the name of a field of an existing Custom Data Type (CDT) to match a renamed database field.

The CDT is backed by a database entity, whose data store has the Automatically Update Database Schema option disabled. The old column name was BIRTHDATE and the new column name is DATE_OF_BIRTH.

How should you proceed?

ADownload the CDT as XSD, make the appropriate changes, and re-upload the XSD. Verify and publish the data store.

BRename the field in the record type in Appian to automatically update the CDT field.

CRename the field in the CDT in Appian. Verify and publish the data store.

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

Definitely not B, that won't work with the schema option disabled!

Wait, can we really just rename it like that? Sounds too easy.

I think A is better. Downloading and re-uploading seems safer.

Option C is the way to go. Just rename it in the CDT.

I vaguely recall that renaming in the record type might not work if the schema isn't set to auto-update. So, I guess I should focus on option C instead.

I feel like we discussed the implications of the database schema being disabled, which might mean I can't just rename it in Appian. Maybe I should go with option A?

I think option C sounds familiar from our practice questions, where we had to rename fields in CDTs. But I’m a bit confused about the verification step.

I remember something about needing to update the CDT directly, but I'm not sure if I should download the XSD or just rename it in Appian.

Hmm, this is a tricky one. With the database schema update option disabled, I'm not sure if any of these options will work smoothly. I might need to double-check the documentation or ask the instructor for guidance on the best approach.

Option B seems like the easiest approach here. If I can just rename the field in the record type, that should update the CDT without having to mess with the database schema. I'll give that a try.

I'm a bit unsure about this one. The question mentions the database schema update option is disabled, so I'm not sure if option C will work. Maybe I should try option A and download the XSD to make the changes.

Hmm, this seems straightforward. I think I'll go with option C and rename the field directly in the CDT. That should update the database schema automatically.

I'm with Gilma on this one. C is the way to go, but keep a fire extinguisher handy, just in case the database decides to throw a party while you're renaming that field.

Ah, the old 'rename the field and hope for the best' scenario. I'd go with C, but I'd also have a backup plan in case something goes wrong. You know, just in case the database decides to rebel against us mortals.

That's a good point, but wouldn't it be safer to make changes in the XSD file first to ensure data integrity?

If the database schema auto-update is disabled, I'd probably go with C. Renaming the field in the CDT is the way to go, just to be safe.

I'd be worried about B causing issues with the data mapping. Gotta be careful with that kind of thing. C seems like the safest bet here.

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.
