TPC-H Test Sets

Updated on 2022-07-26 GMT+08:00

View PDF

You can use Using Commands to Generate TPC-H Test Sets to generate TPC-H test sets or directly use Using Scripts to Generate TPC-H Test Sets to generate TPC-H test sets. We provide all TPC-H Test Sets for your reference.

Using Commands to Generate TPC-H Test Sets

The SQL statements of the 22 standard TPC-H queries can be generated as follows:

cd /data1/script/tpch-kit/TPC-H_Tools_v3.0.0/dbgen
cp qgen queries
cp dists.dss queries
for i in {1..22}
do
    ./qgen -s 1000 -d $i > Q$i
done

The generated query cannot be directly used and needs to be modified as follows:

If the statement contains LIMIT -1, delete LIMIT -1.
Q15: Change CREATE VIEW statements to WITH statements and remove DROP VIEW statements.

Using Scripts to Generate TPC-H Test Sets

You are advised to use the following script to generate TPC-H queries for GaussDB(DWS):

# -*- coding: utf-8 -*-
import os
import sys
import re


def genseq(qgenfile, scale, query_dir):
    flags = os.O_WRONLY | os.O_CREAT | os.O_EXCL

    if not os.path.exists(query_dir):
        os.mkdir(query_dir)

    for i in range(1, 23):
        cmd = qgenfile + ' -s ' + str(scale) + ' -d ' + str(i) + ' > ' + query_dir + '/Q' + str(i)
        os.system(cmd)

    os.chdir(query_dir)
    for i in range(1, 23):
        with open("Q" + str(i), 'r') as fr:
            qlist = list(fr)
        for j in range(len(qlist)):
            if i == 15:
                if 'create view' in qlist[j]:
                    qlist[j] = qlist[j].replace('create view', 'with')
                elif 'l_suppkey;' in qlist[j]:
                    qlist[j] = qlist[j].replace(';\n', ')')
                elif 'drop view' in qlist[j] or 'LIMIT -1' in qlist[j]:
                    qlist[j] = ''

        with os.fdopen(os.open("Q" + str(i), flags, modes), 'w') as fw:
            for z in range(len(qlist)):
                fw.write(qlist[z])

        sys.exit(1)

    genseq(qgen_file_path, int(scale), query_dir)

Save the script as gen_tpch_thpseq.py and save it in the queries directory. Run the python3 gen_tpch_thpseq.py ./qgen 1000 tpch1000x_query command. In the command, 1000 indicates the data scale, and tpch1000x_query indicates the location where 22 SQL statements are saved.
