The following hash index is distributed on o_orderkey (the primary index for the base table Orders) and stored in hash order on o_orderkey:

     CREATE HASH INDEX ord_hidx_4 (o_orderdate) ON orders;

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

     CREATE JOIN INDEX ord_jidx_4 AS
      SELECT o_orderkey, o_orderdate, orders.ROWID 
      FROM orders
     PRIMARY INDEX (o_orderkey);
