Hi, Niels
Thank you for your reply.
I succeeded in loading data by load.sh and executing queries by run.all. Then, I want to compare my query execution result against the reference result, which is provided in xx.ans.
The xx.ans are coming from the tpc-h website and are for the scale factor 1. For the 0.01 we have output in the subdirectory Tests (this is tested every night).
For other sizes the do not have output available (nor has the tpc).

How can I generate the same format as xx.ans? Furthermore, a visual inspection of my query execution results indicate that my results does not match the results stated in xx.ans files.
For example, 01.sql results are as follows:
% sys.lineitem, sys.lineitem, sys.lineitem, sys.lineitem, sys., sys., sys.lineitem, sys., sys., sys.lineitem # table_name % l_returnflag, l_linestatus, sum_qty, sum_base_price, sum_disc_price, sum_charge, avg_qty, avg_price, avg_disc, count_order # name % varchar, varchar, bigint, decimal, decimal, decimal, double, double, double, int # type % 1, 1, 6, 17, 21, 21, 22, 22, 22, 5 # length [ "A", "F", 380456, 532348211.65, 505822441.4861, 526165934.000839, 25.575154611454693, 35785.709306937351, 0.050081339069642378, 14876 ] [ "N", "F", 8971, 12384801.37, 11798257.2080, 12282485.056933, 25.778735632183906, 35588.509683908051, 0.047758620689655168, 348 ] [ "N", "O", 742802, 1041502841.45, 989737518.6346, 1029418531.523350, 25.454987834549879, 35691.129209074395, 0.049931119564099929, 29181 ] [ "R", "F", 381449, 534594445.35, 507996454.4067, 528524219.358903, 25.597168165346933, 35874.006532680178, 0.049827539927526504, 14902 ]

hi,
I am a beginner of MonetDB. I want to run TPC-H benchmark on MonetDB. I found there are SQL queries and related files under monetdb source folder <monetdb-source>/sql/src/benchmark/tpch. I ran the script 'run.all'. But that gave me many errors and did not succeed. Can anyone describe briefly the steps I need to carry out in order to run TPC-H benchmark? Any documentations I can refer to is highly appreciated.
Thanks for trying MonetDB.
The run.all script is mostly used internal but you could adapted.
- it requires a running MonetDB/SQL server
- Then you need to load the data (use the load.sh script for this) By default this will load the 0.01 scale factor of the tpc-H benchmark (the only scale factor for which the data is in the source repository). You could generate different sizes using the dbgen tool inside the
dbgen subdirectory.
- Now run.all should work.
Niels
Thank you.
