调研方向

通过 Python ADBC DBAPI 路径复现该查询，从 cur.execute 和游标关闭路径开始。跟踪 Flight SQL Action::SelectPreparedStatement 错误以及随后对 ClosePreparedStatement 的处理。当除以零能被及时报告，且不再出现 traceback 中显示的会话被窃取和清理错误时，即表示完成。

由索引模型根据 Issue 内容生成。

描述

The following query should report a division by zero:

import adbc_driver_flightsql.dbapi as flight_sql

with flight_sql.connect(uri="grpc://localhost:15432",
                        db_kwargs={"username": "avogelsgesang",
                                   "adbc.flight.sql.rpc.call_header.x-flight-sql-database": "avogelsgesang"
                                   }
                        ) as conn:
   with conn.cursor() as cur:
        cur.execute("SELECT 1/0;")

However, this does not work as expected. Instead cur.execute first hangs for a couple of minutes before then reporting

Traceback (most recent call last):
  File "/home/avogelsgesang/Documents/af-query.py", line 9, in <module>
    cur.execute("SELECT 1/0;")
  File "/home/avogelsgesang/.local/lib/python3.10/site-packages/adbc_driver_manager/dbapi.py", line 669, in execute
    handle, self._rowcount = self._stmt.execute_query()

During handling of the above exception, another exception occurred:
