[jira] [Created] (CALCITE-4916) Need more exception information about "Non-query expression encountered in illegal context"

xuyang created CALCITE-4916:
-------------------------------

             Summary: Need more exception information about "Non-query expression encountered in illegal context"
                 Key: CALCITE-4916
                 URL: https://issues.apache.org/jira/browse/CALCITE-4916
             Project: Calcite
          Issue Type: Improvement
            Reporter: xuyang


As a user, in most cases I was confused with the exception with "Non-query expression encountered in illegal context", and re-check my entire sql even if the sql is too long. I see some issues about this exception have been existed. The root cause is that the exception lacks some necessary information such as  position and expected sequences following. So, maybe the exception information can be improved to be more clear to users.
