------------------------------------

             Summary: In an aggregation validator treats lambda variable names 
as column names
                 Key: CALCITE-7193
                 URL: https://issues.apache.org/jira/browse/CALCITE-7193
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.40.0
            Reporter: Mihai Budiu


This produces validation errors for legal queries:
{code:sql}
SELECT "EXISTS"(ARRAY_AGG(empno), x -> x > 1) AS B FROM emp GROUP BY deptno
{code}

leads to 

{code}
org.apache.calcite.sql.validate.SqlValidatorException: Expression 'X' is not 
being grouped

Clearly, AggChecker should treat lambda parameters differently.
