The following hash index is distributed explicitly on l_shipdate and stored explicitly in value order on l_shipdate:

     CREATE HASH INDEX line_hidx_1 (l_shipdate) ON lineitem
     BY (l_shipdate) 
     ORDER BY (l_shipdate);

Equivalently, you could specify ORDER BY VALUES instead of ORDER BY.

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

     CREATE JOIN INDEX line_jidx_1 AS
      SELECT (l_shipdate), (l_orderkey, lineitem.ROWID) 
      FROM lineitem
      ORDER BY l_shipdate
     PRIMARY INDEX (l_shipdate);
