Retrieving CreatedById of a custom metadata type

Question

Is it possible to query fields like CreatedById on a custom metadata type record? Evidently not, but apparently I should be able to?!

SELECT CreatedById from MyObject__mdt   

No such column 'CreatedById' on entity 'MyObject__mdt'

We can see the field on the object and strangely it can even be referenced in a validation rule.

Answer 1

CreatedById is not available in soap api of custom metadata. Check here:- Custom Metadata Type__mdt

Available fields are:-

1. Custom Field__c
2. DeveloperName
3. isProtected
4. Label
5. Language
6. MasterLabel
7. NamespacePrefix
8. QualifiedApiName

As a workaround, You can create a field with default value as current user id.
