-------------------------------------------
Summary: Nested aggregate windowed query fails
Key: CALCITE-1327
URL: https://issues.apache.org/jira/browse/CALCITE-1327
Project: Calcite
Issue Type: Bug
Reporter: Gautam Kumar Parai
Assignee: Gautam Kumar Parai
Regression from Calcite-750 Allow nested window aggregates.
Calcite allows illegal queries instead of raising an appropriate error. When
executing the following query calcite does not raise the following error.
{code}
select avg(sum(b)) over (partition by b) from t1;
ERROR: Expression 'b' is not being grouped
{code}
