尝试使用 python 和 mariadb 创建查询

问题描述

抱歉，这可能真的很简单，但我是学习代码的新手， 我想全部退回

yesterday = ((dt.date.today()-dt.timedelta(days=1)))    
cur.execute("SELECT * FROM iron_condor WHERE open='yes' AND DATE(buy_date)<DATE(?)"(yesterday))

我要回来了

Traceback (most recent call last):
  File "/home/pi/Documents/openoptions.py",line 86,in <module>
    cur.execute("SELECT * FROM iron_condor WHERE open='yes' AND DATE(buy_date)<DATE(?)"(yesterday))
TypeError: 'str' object is not callable

解决方法

yesterday = ((dt.date.today()-dt.timedelta(days=1)))    
cur.execute("SELECT * FROM iron_condor WHERE open='yes' AND DATE(buy_date)<DATE(?)",(yesterday,))

注意 2 个逗号。您可能需要将 yesterday 转换为 str。
