Timo Walther created FLINK-32470:
------------------------------------
Summary: SqlValidateException should be exposed as
ValidationException
Key: FLINK-32470
URL: https://issues.apache.org/jira/browse/FLINK-32470
Project: Flink
Issue Type: Bug
Components: Table SQL / API, Table SQL / Planner
Reporter: Timo Walther
Assignee: Timo Walther
{{ValidationException}} is the main exception of the Table API and SQL in case
the user did something wrong. Most exceptions are wrapped into
{{ValidationException}}.
Since the parser module has no access to it, it introduces a custom
{{SqlValidateException}}. However, this should not be exposed to users. It
should only serve as an intermediate exception that is translated in
{{FlinkPlannerImpl#validate}}.
{{SqlParserException}} and {{SqlParserEOFException}} could also be simplified
to {{ValidationException}} but at least they are correctly annotated and
located in the {{o.a.f.table.api}} package.
