> Key: FLINK-37064
> URL: https://issues.apache.org/jira/browse/FLINK-37064
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Gateway
> Affects Versions: 2.1.0
> Reporter: Feng Jin
> Priority: Major
> Fix For: 2.0.0
>
>
> By default, when duplicate field names appear in the definition query,
> Calcite automatically appends an index to the field names to prevent
> conflicts. However, when generating a schema based on the query, we should
> explicitly check for and handle field name conflicts instead of relying on
> Calcite’s default behavior. This ensures that the resulting schema is
> consistent with user expectations and avoids unintended naming patterns.
