>
> The query
> {code:java}
> SELECT sal, COUNT(1) AS count_val
> FROM emp t WHERE sal = ?
> GROUP BY sal HAVING sal < 1000 {code}
> gets translated to the following logical plan:
> {code:java}
> LogicalFilter(condition=[<($0, 1000)])
> LogicalAggregate(group=[{0}], COUNT_VAL=[COUNT()])
> LogicalProject(SAL=[$5], $f1=[1])
> LogicalFilter(condition=[=($5, ?0)])
> LogicalTableScan(table=[[CATALOG, SALES, EMP]]) {code}
> However, applying CoreRules.FILTER_REDUCE_EXPRESSIONS to the plan it just
> becomes
> {code:java}
> LogicalValues(tuples=[[]]) {code}
>
