Hi Simon, I am executing q2 on its own, may be I shouldnt have mentioned correlate, but if I dont mention it I get another error:
sqlalchemy.exc.InvalidRequestError: Select statement 'SELECT min(partsupp.ps_supplycost) AS min_1 FROM partsupp, part, supplier, nation, region WHERE part.p_partkey = partsupp.ps_partkey AND supplier.s_suppkey = partsupp.ps_suppkey AND supplier.s_nationkey = nation.n_nationkey AND nation.n_regionkey = region.r_regionkey AND region.r_name = ?' returned no FROM clauses due to auto-correlation; specify correlate(<tables>) to control correlation manually. I am not sure how I should go about it.
