The subsequent examples demonstrate hash indexes based on the following table definition:
CREATE TABLE lineitem ( l_orderkey INTEGER NOT NULL, l_partkey INTEGER NOT NULL, l_suppkey INTEGER, l_linenumber INTEGER, l_quantity INTEGER NOT NULL, l_extendedprice DECIMAL(13,2) NOT NULL, l_discount DECIMAL(13,2), l_tax DECIMAL(13,2), l_returnflag CHARACTER(1), l_linestatus CHARACTER(1), l_shipdate DATE FORMAT 'yyyy-mm-dd', l_commitdate DATE FORMAT 'yyyy-mm-dd', l_receiptdate DATE FORMAT 'yyyy-mm-dd', l_shipinstruct VARCHAR(25), l_shipmode VARCHAR(10), l_comment VARCHAR(44)) PRIMARY INDEX (l_orderkey);
