Apache Spark reassigned SPARK-36698:
------------------------------------
Assignee: (was: Apache Spark)
> Allow expand 'quotedRegexColumnNames' in all expressions when it’s expanded
> to one named expression
> ---------------------------------------------------------------------------------------------------
>
> Key: SPARK-36698
> URL: https://issues.apache.org/jira/browse/SPARK-36698
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Pablo Langa Blanco
> Priority: Minor
>
> With
> {code:java}
> spark.sql.parser.quotedRegexColumnNames=true{code}
> regular expressions are not allowed in expressions like
> {code:java}
> SELECT `col_.*`/exp FROM (SELECT 3 AS col_a, 1 as exp){code}
> I propose to improve this behavior and allow this regular expression when it
> expands to only one named expression. It’s the same behavior in Hive.
> *Example 1:*
> {code:java}
> SELECT `col_.*`/exp FROM (SELECT 3 AS col_a, 1 as exp){code}
> col_.* expands to col_a: OK
> *Example 2:*
> {code:java}
> SELECT `col_.*`/col_b FROM (SELECT 3 AS col_a, 1 as col_b){code}
> col_.* expands to (col_a, col_b): Fail like now
