-----------------------------------
Summary: Display input field name list when throw Cannot resolve
field exception
Key: FLINK-12271
URL: https://issues.apache.org/jira/browse/FLINK-12271
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Reporter: Hequn Cheng
Assignee: Hequn Cheng
Currently, when we select a field that does not exist, an cannot solve field
exception is thrown. For example,
{code:java}
org.apache.flink.table.api.ValidationException: Cannot resolve field [_4]
{code}
It would be better to also display the input field list to indicate existing
fields, such as:
{code:java}
org.apache.flink.table.api.ValidationException: Cannot resolve field [_4],
input field list:[_1, _2, _3].
{code}
