Nico Kruber updated FLINK-21566:
--------------------------------
Labels: stale-major usability (was: stale-major)
> 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
> Priority: Minor
> Labels: stale-major, usability
>
> 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.
