循环将列数据插入到SQL Server数据库中

Question

我是C＃的新手。我的问题是我想使用第7列及以上的数量将ean，描述，书码，价格和折扣插入SQL Server：

我当前的代码可以插入数据，但是数量已经定义。我正在考虑进行循环，但出现错误

  

必须声明标量变量

我不确定我的逻辑是正确的。

这是我的SQL Server表的屏幕截图：

我的代码：

A = pd.merge(A, B['brand','city'], how='left',
                                   left_on='station_uuid', right_on='uuid')

在您的b = [ { "id": "160407", "created": "2017-10-30T09:41:37.960+0000", "items": [ { "field": "status", "fieldtype": "test", "from": "10407", "fromString": "Analysis", "to": "4", "toString": "To Do" } ] }, { "id": "160407", "created": "2019-10-30T09:41:37.960+0000", "items": [ { "field": "status", "fieldtype": "test", "from": "10407", "fromString": "Analysis", "to": "3", "toString": "In Progress" } ] } ] 循环中，您有：

def recursive(obj, path=None):
    if path is None:
        path = []

    # Check for object type and unpacked
    if isinstance(obj, dict):
        for key, value in obj.items():
            # Write path for this key
            new_path = list(path)
            new_path.append(key)

            # Check Status = in progress
            condition = 'to' in obj and '3' == obj['to']
            if condition:
                print(new_path) #Print correct value
                return new_path #None

            recursive(value, path=new_path)

    # Check for list type and unpacked
    elif isinstance(obj, list):
        for i, item in enumerate(obj):
            new_path = list(path)
            new_path.append(i)
            recursive(item, path=new_path)

a = recursive(b) #None

因此，在执行查询之前，您要清除 all 先前添加的参数。
