Question

我的代码有什么问题，

with connect_db() as conn:
    cursor = conn.cursor()
    stmt = """INSERT INTO ip_records ip_address VALUES (%s)"""
    try:
        cursor.execute(stmt, (ip))
    except mysql.connector.Error as err:
        print err
        return

我正在尝试将ip地址作为字符串插入mysql表。但我收到此错误：

1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'ip_address VALUES (192.168.11.111)' at line 1

Answer 1

您缺少将IP视为字符串的""：

with connect_db() as conn:
    cursor = conn.cursor()
    stmt = """INSERT INTO ip_records (ip_address) VALUES (%s)"""
    try:
        cursor.execute(stmt, (ip,))
    except mysql.connector.Error as err:
        print err
        return

编辑您还需要昏迷以将参数作为元组(ip,)而不是(ip)

传递

实际错误是语法错误（因为(ip_address)周围没有括号，而python参数错误是由于元组(ip,)没有逗号引起的错误。

引号不是必需的。

Answer 2

You need to add放在ip_address周围的括号中或将其删除。

尝试在mysql表中将IP地址作为字符串插入时出现错误
