Kyle McCarthy created ARROW-7478: ------------------------------------ Summary: [Rust] [DataFusion] Group by expression ignored unless paired with aggregate expression Key: ARROW-7478 URL: https://issues.apache.org/jira/browse/ARROW-7478 Project: Apache Arrow Issue Type: Bug Components: Rust, Rust - DataFusion Reporter: Kyle McCarthy
GROUP BY expressions are ignored unless the query also contains an aggregate expression. To reproduce you can execute the following query on the aggregate_test_100 data set. {code:java} SELECT c2 FROM aggregate_test_100 GROUP BY c2{code} *Expected:* {{1}} {{2}} {{3}} {{4}} {{5}} *Actual:* {{2}} {{5}} {{...98 more rows...}} The order of the expected isn't necessarily correct since the query doesn't contain an ORDER BY expression. -- This message was sent by Atlassian Jira (v8.3.4#803005)
