JESSE CHEN commented on SPARK-13865:
------------------------------------
Hive, big sql, db2 queries are all generated off corresponding query templates.
Hive apparently generated the one I listed in the initial report (with JOINs).
So this is what I am asking TPC to see why the variant exists in the templates.
Meanwhile, I tested the query, and as expected, Spark SQL isn't able to parse
it with the following errors:
{noformat}

customer.c_customer_sk and d_month_seq between 1200 and 1200+11)
