根因分析
会话因回滚或关闭而过期,尝试对其执行 SQL 会引发此错误。
English
The session has been expired due to a rollback or close, and attempting to execute SQL on it raises this error.
解决方案
-
95% 成功率 Close and create new session
Close the expired session and create a new one: session.close(); session = Session()
-
80% 成功率 Start new transaction
Use session.begin() to start a new transaction if the session is still in a recoverable state.
无效尝试
常见但无效的做法:
- Using expire_all() to revive session 70% 失败
- Creating new session without closing old 50% 失败
