---------------------------------
Summary: Aggregate functions produce wrong results when operating
on null values
Key: DRILL-1342
URL: https://issues.apache.org/jira/browse/DRILL-1342
Project: Apache Drill
Issue Type: Bug
Components: Execution - Codegen
Affects Versions: 0.4.0
Reporter: Aman Sinha
Assignee: Aman Sinha
If all input values are null, we are producing wrong results for certain
aggregate functions. This shows up with the following query on TPC-DS:
{code:sql}
select sum(wr_return_quantity), min(wr_return_quantity) from web_returns where
wr_return_quantity is null;
{code}
