Example: Hash Index With Checksum - Teradata Vantage - Analytics Database

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);
