-------------------------------
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 asĀ
position and expected sequences following. So, maybe the exception information
can be improved to be more clear to users.
