    "Not all parameters were used in the SQL statement")
mysql.connector.errors.ProgrammingError: Not all parameters were used in the SQL statement

Answer 1

尝试一下：

cursor.execute("SELECT * FROM `member` WHERE `username` = %s AND `password` = %s", (USERNAME.get(), PASSWORD.get()))

Answer 2

您的sql执行查询中有一个错误，如果您要在字段中传递，则应该知道如何很好地进行字符串格式化。例如，您编写的代码应该以这种方式编写

query = "SELECT * FROM `member` WHERE `username` = {} AND 
`password` = {}".format (USERNAME.get(), PASSWORD.get())
cursor.execute(query)

由于您只用一行编写整个查询，因此请尝试使用上述更正进行调整。
