The following hash index is created with disk I/O checksum ON:
CREATE HASH INDEX line_hidx_6, CHECKSUM=ON (l.shipdate) ON lineitem BY (l_shipdate) ORDER BY VALUES;
This creates an index that is equivalent in structure to the following join index:
CREATE JOIN INDEX line_jidx_6, CHECKSUM=ON AS SELECT (l_orderkey), (l_shipdate, lineitem.ROWID) FROM lineitem ORDER BY l_orderkey PRIMARY INDEX (l_shipdate);
