lo_orderkey increment from lineorder table

Question

lo_orderkey increment from lineorder table

Hi, i'm using your ssb-dbgen to generate data for 5 tables that are required to evaluate a database.

For some reason, when i generated data for 5 tables with scale factor of 1, the auto increment of lo_orderkey is not working, as you can see in the next image.

Just found out what was my problem. While adding the constraints in my database (CockroachDB) there was missing a primary key in lineorder table, lo_linumber. The following command fixes the duplicate keys error ALTER TABLE lineorder ADD PRIMARY KEY(lo_orderkey, lo_linenumber); . This is where i got the information https://seanstuber.com/2017/06/14/setting-up-the-star-schema-benchmark-ssb-in-oracle/

Wait, so - is the generation wrong? Also, what did you mean by "5 tables"?

Hi @eyalroz , i think the generation is not wrong. As i said before there was missing a primary key in lineorder constraint in /doc/ssb.ri at line 22. By five tables i meant, linorder, date, supplier, customer, and part tables. Sorry if my english is a bit confusing.
