Alessandro Solimando commented on CALCITE-7485:
-----------------------------------------------
Makes sense, but to be sure maybe you can look this up in the SQL standard or
verify with Postgres or similar that this is actually the case?
> FIRST_VALUE/LAST_VALUE should only be defined for window aggregates
> -------------------------------------------------------------------

> Key: CALCITE-7485
> URL: https://issues.apache.org/jira/browse/CALCITE-7485
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.41.0
> Reporter: Yu Xu
> Priority: Major
>
> FIRST_VALUE and LAST_VALUE are only defined for window aggregates, but can be
> used without window clause in current main branch.
> test case would be passed as follow：
>
> {code:java}
> @Test void testFirstAndLastAggFunctionsOfGroupByKeys() {
> final String sql = "select sal, first_value(sal) as sal_first,
> last_value(sal) as sal_last from emp group by sal, deptno\n";
> sql(sql).check();
> } {code}
> maybe we should fix the issue.
