> URL: https://issues.apache.org/jira/browse/SPARK-30249
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Rakesh Raushan
> Priority: Minor
>
> Column names such as `a:b` , `??`, `,,`, `^^` , `++`etc are allowed when we

> While when we are creating tables with `orc` all such column names are marked
> as invalid and analysis exception is thrown.
> These column names should also be not allowed for parquet tables as well.
