mysql.connector.errors.ProgrammingError: 1054 (42S22): 'where 子句'中的未知列

如何解决mysql.connector.errors.ProgrammingError: 1054 (42S22): 'where 子句'中的未知列

有一个函数 get_show_listing 查询 MysqL 数据库并根据传递的参数（或缺少）过滤集合。在对传递参数的情况进行单元测试时，会引发以下错误。我想了解导致此错误的原因；尤其是传递给函数的任何参数。

            return func(cursor,*args,**kwargs)
    return wrapper_db_connect
