Join Index Definition - Teradata Vantage

The following statement defines a join index on these tables. Subsequent examples demonstrate the effect of this join index on how the Optimizer processes queries.

     CREATE JOIN INDEX order_join_line
      AS SELECT (l_orderkey, o_orderdate, o_custkey,
                 o_totalprice),
                (l_partkey, l_quantity, l_extendedprice, l_shipdate)
      FROM lineitem LEFT JOIN orders ON l_orderkey = o_orderkey
      ORDER BY o_orderdate
      PRIMARY INDEX (l_orderkey);

      *** Index has been created.
