Summary: Enrich the error information to user
Key: FLINK-9625
URL: https://issues.apache.org/jira/browse/FLINK-9625
Project: Flink
Issue Type: Improvement
Reporter: mingleizhang
Assignee: mingleizhang
When the fields too many, and the types do not match with it would cause the
below error. I think we should tell the users which field type does not match.
{code:java}
Exception in thread "main" org.apache.flink.table.api.TableException: Result
field does not match requested type. Requested: String; Actual: Integer
