Teradata Vantage™

Vantage cannot issue standard database transaction locking against data in external object store, therefore these queries behave as if the foreign table has only an access lock (as if you used the LOCKING TABLE … FOR ACCESS request modifier).

If you perform a join between a foreign table and a Vantage native table, normal transaction locking rules still apply to the Vantage table.
