我在SQL服务器中有一个数据透视表，我用查询创建。列是月，行是按客户ID，枢轴中的值是每个月的订阅金额的总和。我希望能够每个月使用该月的新数据更新这个数据，但我不确定如何完全重新创建表格。
有没有办法创建一个新列（对于新月）并使用UPDATE用客户的总计订阅金额填充它？
这是我创建表格的查询：
SELECT * INTO [Service Contract Data].[dbo].[Pivot_Results] FROM [Service Contract Data].[dbo].[filtered_data]
PIVOT (SUM([Service Contract Data].[dbo].[filtered_data].[Subscription Amount])
FOR filtered_data.[Month]
