错误：Cursor'对象没有属性'_last_executed [英] Error: Cursor' object has no attribute '_last_executed

问题描述

我有这个游标

cursor.execute("SELECT price FROM Items WHERE itemID = ( 
                  SELECT item_id FROM Purchases 
                  WHERE purchaseID = %d AND customer_id = %d)", 
                  [self.purchaseID, self.customer])

我得到这个错误

'Cursor' object has no attribute '_last_executed'

但是当我尝试这样：

cursor.execute("SELECT price FROM Items WHERE itemID = ( 
                  SELECT item_id FROM Purchases 
                  WHERE purchaseID = 1 AND customer_id = 1)", 
                  )

没有错误。如何解决这个问题？

there is no error. How do I fix this?
