Root Cause

A ROLLBACK command was issued without a corresponding BEGIN TRANSACTION, or a savepoint name was used that does not exist.

中文

发出了 ROLLBACK 命令，但没有对应的 BEGIN TRANSACTION，或者使用了不存在的保存点名称。

Workarounds

  1. 95% success Wrap the ROLLBACK in a try-except block and only execute it if a transaction is active. In Python: `try: cursor.execute('ROLLBACK') except sqlite3.OperationalError: pass`. Alternatively, use a context manager: `with connection: cursor.execute(...)` which auto-commits/rolls back.

  2. 90% success Review the code to ensure every ROLLBACK is paired with a BEGIN TRANSACTION. Use a connection wrapper that tracks transaction state (e.g., a flag `in_transaction` set to True on BEGIN and False on COMMIT/ROLLBACK).

Dead Ends

Common approaches that don't work:

  1. 60% fail

    If the code already has a transaction, this creates nested transactions that may not be handled correctly, leading to 'cannot commit - no transaction is active' errors later.

  2. 90% fail

    The WAL mode affects concurrency and crash recovery, not transaction management. It does not fix missing transactions.
