-----------------------------------
Summary: Improve error message for "Unsupported casting"
Key: FLINK-21566
URL: https://issues.apache.org/jira/browse/FLINK-21566
Project: Flink
Issue Type: New Feature
Components: Table SQL / API
Affects Versions: 1.12.1
Reporter: Nico Kruber
In a situation like from FLINK-21565, neither the error message {{Unsupported
casting from TINYINT to INTERVAL SECOND(3)}}, nor the exception trace (see
FLINK-21565) gives you a good hint on where the error is, especially if you
have many statements with TINYINTs or operations on these.
The query parser could highlight the location of the error inside the SQL
statement that the user provided.
