The following hash index is distributed implicitly on l_orderkey, the primary index for the base table lineitem, and also stored implicitly in hash order on l_orderkey:

     CREATE HASH INDEX line_hidx_4 (l_shipdate) ON lineitem;

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

     CREATE JOIN INDEX line_jidx_4 AS
      SELECT (l_orderkey), (l_shipdate, lineitem.ROWID) 
      FROM lineitem
     PRIMARY INDEX (l_orderkey);
