Dandandan opened a new issue, #9581: URL: https://github.com/apache/arrow-datafusion/issues/9581
### Describe the bug This returns a execution error. We should likely return a null value instead like other aggregation functions. ### To Reproduce ``` create table t(a int); select APPROX_PERCENTILE_CONT(a, 0.5) from t; ``` This returns ```Execution error: aggregate function needs at least one non-null element``` ### Expected behavior Return null value. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
