The following example shows how to get and compare the stored metadata values and the in-memory values of the Resource Governor configuration.

use master
go
-- Get the stored metadata.
select 
object_schema_name(classifier_function_id) as 'Classifier UDF schema in metadata', 
object_name(classifier_function_id) as 'Classifier UDF name in metadata'
from 
sys.resource_governor_configuration
go
-- Get the in-memory configuration.
select 
object_schema_name(classifier_function_id) as 'Active classifier UDF schema', 
object_name(classifier_function_id) as 'Active classifier UDF name'
