----------------------------------------------
Summary: Filter on Grouping__ID does not work properly
Key: HIVE-12223
URL: https://issues.apache.org/jira/browse/HIVE-12223
Project: Hive
Issue Type: Bug
Components: Logical Optimizer
Affects Versions: 1.3.0, 2.0.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Fix For: 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. A possible solution is
to transform the placeholder constant into a function over the grouping keys.
