>             Project: Hive
>          Issue Type: Bug
>          Components: Logical Optimizer
>    Affects Versions: 1.3.0, 2.0.0

> Consider the following query:
> {noformat}
> SELECT key, value, GROUPING__ID, count(*)
> FROM T1
> GROUP BY key, value
> GROUPING SETS ((), (key))
> HAVING GROUPING__ID = 1
> {noformat}
> This query will not return results. The reason is that a "constant" placeholder is introduced by SemanticAnalyzer for the GROUPING\__ID column. At execution time, this placeholder is replaced by the actual value of the GROUPING\__ID. As it is a constant, the Hive optimizer will evaluate statically whether the condition is met or not, leading to incorrect results. We should be able to recognize the placeholder and avoid that Hive optimizer evaluates it statically.
