gianm opened a new issue #10204:
URL: https://github.com/apache/druid/issues/10204
This query on the builtin example "wikipedia" dataset:
```
SELECT
(SELECT MIN(__time) FROM wikipedia w2 WHERE w1.countryName =
w2.countryName) AS firstseen,
countryName
FROM wikipedia w1
GROUP BY countryName
ORDER BY firstseen
```
Throws the following error during planning:
```
