weizuo93 opened a new issue #7510: URL: https://github.com/apache/incubator-doris/issues/7510
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Version master branch. (commit id : 6e052f4ede6beea1d561113f24252c32fc7fc743) ### What's Wrong? The return value type of the function `percentile_approx` would be parsed as double type. When `nan` value returned by function `percentile_approx`, the return value can not be parsed as double by JDBC and the exception `Bad format for number 'nan' in column ...` will be thrown by JDBC. The stack is shown as following： ``` java.sql.SQLException: Bad format for number 'nan' in column 1. at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:965) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:898) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:887) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:861) at com.mysql.jdbc.ResultSetImpl.getDoubleInternal(ResultSetImpl.java:2324) at com.mysql.jdbc.ResultSetImpl.getDoubleInternal(ResultSetImpl.java:2264) at com.mysql.jdbc.ResultSetImpl.getDouble(ResultSetImpl.java:2232) at com.mysql.jdbc.ResultSetImpl.getObject(ResultSetImpl.java:4506) at org.example.JdbcService.nanTest(JdbcService.java:93) ``` ### What You Expected? The return value can be parsed by JDBC successfully. ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
