Hi @AlexVB ,

The current UDF implementation in Databricks requires referencing the UDF location with select my_catalogue.my_schema.my_udf() or executing SQL from that schema because Databricks organizes database objects using a three-tier hierarchy: Catalog, Schema (or Database), and Data Objects (such as Functions). This structure mandates specifying the catalog and schema to locate the UDF unless it is a temporary function scoped at the session level, which does not require such specification.
