> Key: SPARK-36005
> URL: https://issues.apache.org/jira/browse/SPARK-36005
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.2
> Reporter: Sun BiaoBiao
> Priority: Major
>
> In https://github.com/apache/spark/pull/32109 this pr, we introduced the
> char/varchar type,
> As described in this issue:
> To be safe, this PR doesn't add char/varchar type to the query
> engine(expression input check, internal row framework, codegen framework,
> etc.). We will replace char/varchar type by string type with metadata
> (Attribute.metadata or StructField.metadata) that includes the original type
> string before it goes into the query engine. That said, the existing code
> will not see char/varchar type but only string type.
> so The canCast method of type of char/varchar needs to be consistent with
> StringType
