Azure Sql数据库查询

Question

我已经在Azure上创建了一个数据库，我也可以通过设置防火墙等从本地服务器访问Azure Sql数据库

我注意到的是，当我进行表架构更改（例如，创建新表或向现有表添加新列）时，更改不会反映在Azure应用程序上（尽管我可以在Azure SQL数据库查询编辑器中看到最新的表更改） ）

我尝试修改Azure提供的默认TODO表的示例TODO应用程序。

从Azure下载应用程序并运行它之后，通过从TODO表加载适当的数据，应用程序可以正常运行。

但是，当我向现有的TODO表中添加新的列/重命名列时，更改DOT文件以在api服务中添加新列并发布了该服务。 APP停止显示具有连接错误的数据...

Answer 1

在MyApp08112017.QSCustomerViewController + d__9.MoveNext（）[0x0008c]从Azure \\ MyApp08112017_Xamarin_iOS \\ MyApp08112017 \\ QSCustomerViewController.cs：33的E：\\ Workspaces \\ ATM Project \\ ZIPs中

根据错误消息，您将C＃后端用于Azure移动应用程序。 要添加新表，您需要定义表的模型并为其创建表控制器。 要编辑列，可以编辑表模型。 在将后端发布到Azure之前，需要先执行代码迁移，您可以通过add-migration手动创建迁移文件，并利用命令update-database来应用现有迁移。 另外，您可以启用自动编码优先迁移。 更多细节，您可以参考adrian hall的书《 实现表控制器》 。 移动者，您也可以检查处理发布失败 。
