public class TPCHQuery10$ extends Object
The original query can be found at [http://www.tpc.org/tpch/spec/tpch2.16.0.pdf](http://www.tpc.org/tpch/spec/tpch2.16.0.pdf) (page 45).
This program implements the following SQL equivalent:
SELECT c_custkey, c_name, c_address, n_name, c_acctbal SUM(l_extendedprice * (1 - l_discount)) AS revenue, FROM customer, orders, lineitem, nation WHERE c_custkey = o_custkey AND l_orderkey = o_orderkey AND YEAR(o_orderdate) > '1990' AND l_returnflag = 'R' AND c_nationkey = n_nationkey GROUP BY c_custkey, c_name, c_acctbal, n_name, c_address
Compared to the original TPC-H query this version does not print c_phone and c_comment, only filters by years greater than 1990 instead of a period of 3 months, and does not sort the result by revenue..
Input files are plain text CSV files using the pipe character ('|') as field separator as generated by the TPC-H data generator which is available at [http://www.tpc.org/tpch/](a href="http://www.tpc.org/tpch/).
TPCHQuery10 --customer <path> --orders <path> --lineitem <path> --nation <path> --output <path>
This example shows how to use: - tuple data types - build-in aggregation functions - join with size hints
