The following hash index is distributed on its primary index o_custkey and stored in row-hash order on o_custkey:

     CREATE HASH INDEX ord_hidx_2 (o_custkey) ON orders
     BY (o_custkey)
     ORDER BY HASH (o_custkey);

This creates an index that is equivalent in structure to the following join index:

     CREATE JOIN INDEX ord_jidx_2 AS
      SELECT (o_custkey), (o_orderkey, orders.ROWID) 
      FROM orders
     PRIMARY INDEX (o_custkey);
