Query #2 Inaccurate Output #33

Closed riya-verma-23 closed 7 months ago

riya-verma-23 commented 2 years ago

When running query number 2 separately from other queries, it outputs the error that it is unable to find the column s_acctbal. I believe the error lies in the order of joining the result table in the final query which causes loss of the desired columns in the final output. I think this is the reason why query #2 times are much lower compared to other queries, because the query isn't executed completely as it throws an error.

The queries did run successful at the time of the benchmarks. We have asserted the correct output for every query.

I think we might have introduced a bug upstream.

How are you running the query? For me it runs correctly:

shape: (100, 8)
