Review Comment:
Perhaps here's the reason you are looking for:
https://github.com/apache/druid/blob/master/sql/src/main/java/org/apache/druid/sql/calcite/planner/QueryHandler.java#L692
However, in this case, it seems like we do know the exact reason why the
query failed - It's due to the absence of a time column. So perhaps change the
wording to be more assertive.
