描述

### Describe the enhancement requested

Some followups from apache/arrow#38404 and apache/arrow#33475. For anyone interested in working on the driver, feel free to file specific issues for any one of these points.

- Add support for complex types
- Add integration testing with databases supporting Flight SQL
- Handle `null` values for bind parameters
- Use a more appropriate exception than `RuntimeException` in AvaticaParameterBinder
- Not all servers can always provide an accurate type for bind parameters. What should we do there? Note that ADBC uses NA/NullType as a wildcard/placeholder type here. This isn't specified in Flight SQL itself, but perhaps we could adopt that convention as well. (Also see: apache/arrow#38549)
- Improve the error message to make it clear when the server hasn't sent a parameter schema https://github.com/apache/arrow-java/issues/121

研究方向

從 Flight SQL JDBC 驅動程式繫結工作以及名為 AvaticaParameterBinder 的進入點開始。將寬泛的清單拆分為一個範圍明確的後續事項,然後找出與 Flight SQL 資料庫相關的整合涵蓋範圍,並為該項目定義完成標準。
