多線程和Python SQL3

Question

我使用Python 2.7和SQLite3數據庫。我想在數據庫上運行需要一些時間的更新查詢。另一方面，我不希望用戶必須等待。 因此，我想開始一個新的線程來做數據庫更新。

Python引發錯誤。有沒有一種有效的方式來告訴數據庫在它自己的線程中執行更新，而無需等待線程完成？

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

至於示例去我試圖寫一個Anki插件。產生這個錯誤的附加組件的代碼是：

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
