Apache Spark reassigned SPARK-34856:
------------------------------------
Assignee: Apache Spark (was: Gengliang Wang)
> ANSI mode: Allow casting complex types as string type
> -----------------------------------------------------
>
> Key: SPARK-34856
> URL: https://issues.apache.org/jira/browse/SPARK-34856
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: Gengliang Wang
> Assignee: Apache Spark
> Priority: Major
>
> Currently, complex types are not allowed to cast as string type. This breaks
> the Dataset.show() API. E.g
> {code:java}
> scala> sql(“select array(1, 2, 2)“).show(false)
> org.apache.spark.sql.AnalysisException: cannot resolve ‘CAST(`array(1, 2, 2)`
> AS STRING)’ due to data type mismatch:
> cannot cast array<int> to string with ANSI mode on.
> {code}
