True when the item names a CTE that is in scope where it is read: an unqualified name that

one. A schema, dbo included, always makes the item a real table or view.
The schema of the table or function as written, without quotes; empty when unqualified. A
three-part name keeps its database (database.schema), so it never matches a view in this
database.
The table or view name without quotes; empty when the item is not a table or view.
One FROM item a parsed statement reads: a table or view, or a table function.
