Review Comment:
I tried removing the `LIMIT`. I don't understand why, but the presence
causes a different type of exception to be thrown. With `LIMIT` we get
`SqlException`, without `CalciteException`. The message and origin stays the
same.
To be consistent with other tests, I left the `LIMIT`. Let me know what do
you think.
