多线程和Python SQL3

Question

我使用Python 2.7和SQLite3数据库。我想在数据库上运行需要一些时间的更新查询。另一方面，我不希望用户必须等待。 因此，我想开始一个新的线程来做数据库更新。

Python引发错误。有没有一种有效的方式来告诉数据库在它自己的线程中执行更新，而无需等待线程完成？

line 39, in execute ProgrammingError: SQLite objects created in a thread can only be used in that same thread.The object was created in thread id 3648 and this is thread id 6444

至于示例去我试图写一个Anki插件。产生这个错误的附加组件的代码是：

from anki.sched import Scheduler 
import threading 

def burying(self, card): 
    buryingThread = threading.Thread(target = self._burySiblings, args = (card,)) 
    buryingThread.start() 

def newGetCard(self): 
    "Pop the next card from the queue. None if finished." 
    self._checkDay() 
    if not self._haveQueues: 
     self.reset() 
    card = self._getCard() 
    if card: 
     burying(self, card) 
     self.reps += 1 
     card.startTimer() 
     return card 

__oldFunc = Scheduler.getCard 
Scheduler.getCard = newGetCard
