>                 URL: https://issues.apache.org/jira/browse/SPARK-38363
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL
>    Affects Versions: 3.3.0
>            Reporter: Gengliang Wang
>            Assignee: Apache Spark
>            Priority: Major
>
> When executing df.summary(), Spark SQL converts String columns as Double for the 
> percentiles/mean/stddev metrics. 
> This can cause runtime errors with ANSI mode on. 
> Since this API is for getting a quick summary of the Dataframe, I suggest using "TryCast" for the problematic stats so that the API still works under ANSI mode.
