drusso opened a new pull request #8836: URL: https://github.com/apache/arrow/pull/8836
This change is a proposal to broaden the SQL planner's support for queries such as: * GROUP BY without an aggregation ``` SELECT a FROM t GROUP BY a; SELECT MAX(b) FROM t GROUP BY a; SELECT MAX(b) + 1 FROM t GROUP BY a; SELECT MAX(b + 1) FROM t GROUP BY a; SELECT a + 1, MAX(b) FROM t GROUP BY a + 1; ``` In these queries Largely the changes loosen some of the restrictions, broadening support for more queries, but there There are two existing tests where behaviour has changed: * `select_7480_1()`: this scenario is not all of the GROUP BY expressions are in the SELECT expressions - this is an internal change, since the loosening this restriction is part of the proposed * `select_nested_with_filters()`: ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
