ranflarion opened a new issue, #26125: URL: https://github.com/apache/datafusion/issues/26125
### Describe the bug datafusion-spark's `char` fails on a NULL scalar argument with `Execution error: The argument must be an Int64 array or scalar.`, where Spark returns NULL. `spark_chr` (`datafusion/spark/src/function/string/char.rs`) handles `ScalarValue::Int64(Some(_))` and sends `Int64(None)` to that error. NULL rows of an array argument already return NULL. ### To Reproduce ```sql SELECT char(NULL::INT); ``` ### Expected behavior `NULL`, as Spark returns for `char(NULL)`. -- This is an automated message from the Apache Git Service.
