James Kim created CALCITE-4635: ---------------------------------- Summary: Distinct on aggregate window functions produce wrong result Key: CALCITE-4635 URL: https://issues.apache.org/jira/browse/CALCITE-4635 Project: Calcite Issue Type: Bug Reporter: James Kim
Using distinct with an aggregate window function like: select (count(distinct \"T\".\"X\") over (partition by \"T\".\"Y\")) from (VALUES (4, 6), (4, 1), (2, 1), (2, 1)) as T(x, y) produces wrong result; the distinct function is not being applied i.e., the result of the above query should be (1, 2) but currently it returns (1, 3). After creating and running a test on RelOptRulesTest, I saw the distinct flag is not being dropped, so I suspect this might be an issue on execution side. I looked into resolving this issue but have been stuck as to where the fix should be. For now I could throw with a RESOURCE.functionQuantifierNotAllowed error in SqlOverOperator until this is fixed. -- This message was sent by Atlassian Jira (v8.3.4#803005)
