Apache Spark reassigned SPARK-39497:
------------------------------------
Assignee: Apache Spark (was: Gengliang Wang)
> Improve the analysis exception of missing map key column
> --------------------------------------------------------
>
> Key: SPARK-39497
> URL: https://issues.apache.org/jira/browse/SPARK-39497
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Gengliang Wang
> Assignee: Apache Spark
> Priority: Minor
>
> Sometimes users forgot to add single quotes on the map key string literal,
> for example `map_col[a]`. In such a case, the Analyzer will throw an
> exception:
> {code:java}
> [MISSING_COLUMN] Column 'struct.a' does not exist. Did you mean one of the
> following? ...{code}
> We can improve this message by saying that the user should append single
> quotes if the map key is a string literal.
