Root Cause

The session has been expired due to a rollback or close, and attempting to execute SQL on it raises this error.

generic

中文

会话因回滚或关闭而过期，尝试对其执行 SQL 会引发此错误。

Workarounds

  1. 95% success Close and create new session 
    Close the expired session and create a new one: session.close(); session = Session()
  2. 80% success Start new transaction 
    Use session.begin() to start a new transaction if the session is still in a recoverable state.

Dead Ends

Common approaches that don't work:

  1. Using expire_all() to revive session 70% fail

  2. Creating new session without closing old 50% fail
