Blocker Description
Note: The query in the test case doesn't look meaningful, but I'm not sure the problem is limited to such nonsensical queries. If the analysis shows that it indeed does, I don't object demoting it from a blocker.
CREATE TABLE t (f INT); |
INSERT INTO t VALUES (1),(2); |
SELECT DISTINCT CONVERT(STDDEV(f), CHAR(16)) AS f1, UUID() AS f2 FROM t GROUP BY f2 WITH ROLLUP; |

# Cleanup

DROP TABLE t; |
