我正在尝试使用元组通过数据帧更新mysql，但是我被卡住了，我不知道问题出在mydatabase还是我的代码
这是我使用的全部代码

all_data = pd.read_sql('SELECT * FROM govtracker', engine)

'Body', 'From: (Name)', 'To: (Name)'],

myOutlook_inBox.columns = myOutlook_inBox.columns.str.replace(' ', '')
#this object extract 5 chars and 5 numbers from specific column in csv
replaced_sbj_value = myOutlook_inBox['Subject']
.str.extract(pat='(L(?:DEL|CAI|SIN).\d{5})').dropna()
#this columns I want to filter in database
myOutlook_inBox["Subject"] = replaced_sbj_value
# this conditions filters and get and dublicate repeated data from outlook

现在，我将简要说明我的代码和情况
因此，在创建连接并读取熊猫后，我开始创建条件，此条件正在过滤并从pandas数据框中提取了一些值，因为结果是列数据框包含一些值，所以从现在开始，我将使用此输出作为过滤条件通过使用Join在我的datbase中，所以现在我想根据通过使用元组过滤的值来更新come列，并创建一个简单的查询，但是我被卡住了，我发现了此错误，所以如果有人可以帮助我解决这种情况，我谢谢他/她
希望每一件事都足够清楚
