描述
### Describe the bug, including details regarding any error messages, version, and platform.
Here's an example of code that causes the issue:
```## Doesn't work when the params are set on a created column on the fly
# stmt = text("SELECT *, (CASE WHEN (`OID` IS NULL) THEN :x ELSE :y END) as Temp FROM `Dynamic.Schema.Dts`.`Table`")
# rows = con.execute(stmt, {'x': 1, 'y': 0}).fetchall()
```
I'm unable to select with this query because I create a column on fly in runtime, after it's created I would like to query it.
And it's seems impossible.
I've tested it with: 15.0.2 and it still has the same issue.
Thank you in advance for the help.
If anymore information is required please comment that.

贡献指南
调研方向
首先,使用报告的 15.0.2 版本,通过 FlightRPC 和 flight-jdbc 组件重现所提供的查询,然后跟踪运行时创建的列的参数是如何处理的。该 issue 未指定源文件或测试;当查询能够使用所提供的动态参数成功执行,并且有一个回归测试覆盖此行为时,即表示完成。
由索引模型根据 Issue 内容生成。
