The behaviour of GROUP BY const in analyzer is slightly different, it still preserves the const property from the subqueries, and that's why it simply do not execute filters after GROUP BY, but simply one time for the const. The initial bug was about predicate pushdown not about GROUP BY const, so I will update the test. I've also tested the initial bug with fiddle and the new test is idential: - 19.17 (without the fix) - https://fiddle.clickhouse.com/312a48f4-6a5b-411d-a4bb-4b1a757effaf - 20.2 (with the fix) - https://fiddle.clickhouse.com/4e1ad2e5-1c03-4ce7-9ac3-e878ccfae83a Refs: https://github.com/ClickHouse/ClickHouse/pull/8503 Refs: https://github.com/ClickHouse/ClickHouse/issues/5682 Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>
