SQL: grouping by values resulting from fields compared with constants #34543
Description
At the moment something like select (3 < languages) as multi_language, count(*) from test_emp group by multi_language doesn't work. The exception is not entirely accurate in my opinion and the ES query used in this scenario is very similar with the one from #34400.
