Python Selenium MySQL-如果ID不存在，则插入

我有以下代码：

def read_excel_all_members(mycursor, mydb):
with open('.\\docs\\allMembers.csv') as allMembersCSV:
    csv_reader_object = csv.reader(allMembersCSV, delimiter=';')
    next(csv_reader_object)
    sql = "INSERT INTO allMembers (idnr, lastname, firstname) VALUES (%s, %s, %s)"
    for row in csv_reader_object:
        sql2 = 'SELECT count(*) FROM allMembers WHERE idnr =' + row[0]
        exists = mycursor.execute(sql2)
        if not exists != 0:
            val = [
                (row[0], row[1], row[2])
            ]
            mycursor.executemany(sql, val)
mydb.commit()

但是我总是会遇到一个错误-如果行[0]此时不存在，我只想插入该行

我的代码有什么问题

错误：

  File "C:/Users/usera/PycharmProjects/untitled1/console.py", line 38, in <module>
    functions.read_excel_all_members(mycursor, mydb)
  File "C:\Users\usera\PycharmProjects\untitled1\functions.py", line 128, in read_excel_all_members
    exists = mycursor.execute(sql2)
  File "C:\Users\usera\PycharmProjects\untitled1\venv\lib\site-packages\mysql\connector\cursor.py", line 521, in execute

    raise errors.InternalError("Unread result found")
mysql.connector.errors.InternalError: Unread result found``` 


Pls help me.

The CSV is like:

> ID;Familienname;Vorname
1538;Jakob;Schwarz

文件“C:/Users/usera/PycharmProjects/untitled1/console.py”，第38行，在
函数。读取所有成员（mycursor、mydb）
文件“C:\Users\usera\PycharmProjects\untitled1\functions.py”，第128行，在read\u excel\u all\u成员中
exists=mycursor.execute（sql2）
文件“C:\Users\usera\PycharmProjects\untitled1\venv\lib\site packages\mysql\connector\cursor.py”，第521行，在execute中
self.\u connection.handle\u unread\u result（）
文件“C:\Users\usera\PycharmProjects\untitled1\venv\lib\site packages\mysql\connector\connection.py”，第1059行，在handle\u unread\u result中
引发错误。内部错误（“找到未读结果”）
mysql.connector.errors.InternalError:找到未读结果`
请帮帮我。
CSV类似于：
>身份证；家名；沃名称
1538;雅各布；施瓦兹

现在我有了解决方案：

def read_excel_all_members(mycursor, mydb):
with open('.\\docs\\allMembers.csv') as allMembersCSV:
    csv_reader_object = csv.reader(allMembersCSV, delimiter=';')
    next(csv_reader_object)
    sql = 'INSERT INTO allMembers (idnr, lastname, firstname) VALUES (%s, %s, %s)'
    for row in csv_reader_object:
        sql2 = 'SELECT count(*) FROM allMembers WHERE idnr =' + row[0]
        mycursor.execute(sql2)
        result = mycursor.fetchone()
        if result == (0,):
            val = [
                (row[0], row[1], row[2])
            ]
            mycursor.execute(sql, val[0])
mydb.commit()
