AsTableIdentifier
Extract legacy table identifier from a multi-part identifier.
Extract legacy table identifier from a multi-part identifier.
For legacy support only. Please use CatalogAndIdentifier instead on DSv2 code paths.

CatalogAndIdentifier
Extract catalog and identifier from a multi-part name with the current catalog if needed.
Extract catalog and identifier from a multi-part name with the current catalog if needed. Catalog name takes precedence over identifier, but for a single-part name, identifier takes precedence over catalog name.
Note that, this pattern is used to look up permanent catalog objects like table, view, function, etc. If you need to look up temp objects like temp view, please do it separately before calling this pattern, as temp objects don't belong to any catalog.

Extract catalog and namespace from a multi-part name with the current catalog if needed. Catalog name takes precedence over namespaces.
