The following hash index is distributed implicitly on l_orderkey, the primary index for the base table lineitem, and stored explicitly in value order on l_shipdate:
CREATE HASH INDEX line_hidx_5 (l_shipdate) ON lineitem ORDER BY (l_shipdate);
Equivalently, you could specify ORDER BY VALUES instead of ORDER BY.
Note that the ORDER BY column list complies with the rules that it be limited to a single column, that the column must be in the column_name_1 list, must be a numeric type, and must be four or fewer bytes.
This creates an index that is equivalent in structure to the following join index:
CREATE JOIN INDEX line_jidx_5 AS SELECT (l_shipdate), (l_orderkey, lineitem.ROWID) FROM lineitem ORDER BY l_shipdate PRIMARY INDEX (l_orderkey);
