…T field and alias causes validation error This PR restricts the alias/ordinal expanding GROUP BY expr to identifier or CUBE/ROLLUP/GROUPING SETS top level expression. For example: select replace(name, 'a', 'b') as name from users group by replace(name, 'a', 'b') The name in GROUP BY clause will not be replaced by replace(name, 'a', 'b'), it will be resolved as users.name. SELECT empno + deptno AS x, empno - deptno AS y FROM emp GROUP BY ROLLUP(x, y, empno) The x, y in GROUP BY clause will be replaced by empno + deptno, empno - deptno. -- This is an automated message from the Apache Git Service.
