[GitHub] [incubator-doris] weizuo93 opened a new issue #7510: [Bug] 'nan' value returned by function 'percentile_approx' can not be parsed as double type by JDBC

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_
