C# EF迁移：参数@objname不明确或声明的@objtype（列）错误

我正在尝试使用迁移更新我的数据库。 当我手工删除所有表格，然后手工重新创建时，我可能把事情搞砸了

我首先使用代码，Add Migration命令告诉我：

 public override void Up()
        {
        DropForeignKey("[dbo.Products]", "[Bundle_Id]", "[dbo.Bundles]");
        DropForeignKey("[dbo.Defects]", "[Product_Id]", "[dbo.Products]");
        DropForeignKey("[dbo.Defects]", "[User_Id]", "[dbo.Users]");
        RenameColumn(table: "[dbo.Products]", name: "[Bundle_Id]", newName: "[Bundles_BundlesId]");
        RenameColumn(table: "[dbo.Defects]", name: "[Product_Id]", newName: "[Products_ProductsId]");
        RenameColumn(table: "[dbo.Defects]", name: "[User_Id]", newName: "[Users_UsersId]");
        RenameIndex(table: "[dbo.Products]", name: "[IX_Bundle_Id]", newName: "[IX_Bundles_BundlesId]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_Product_Id]", newName: "[IX_Products_ProductsId]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_User_Id]", newName: "[IX_Users_UsersId]");
        DropPrimaryKey("[dbo.Bundles]");
        DropPrimaryKey("[dbo.Defects]");
        DropPrimaryKey("[dbo.Products]");
        DropPrimaryKey("[dbo.Users]");
        AddColumn("[dbo.Bundles]", "[BundlesId]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Defects]", "[DefectsId]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Defects]", "[ProductsId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Defects]", "[UsersId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Products]", "[ProductsId]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Products]", "[BundlesId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Users]", "[UsersId]", c => c.Long(nullable: false, identity: true));
        AddPrimaryKey("[dbo.Bundles]", "[BundlesId]");
        AddPrimaryKey("[dbo.Defects]", "[DefectsId]");
        AddPrimaryKey("[dbo.Products]", "[ProductsId]");
        AddPrimaryKey("[dbo.Users]", "[UsersId]");
        AddForeignKey("[dbo.Products]", "[Bundles_BundlesId]", "[dbo.Bundles]", "[BundlesId]");
        AddForeignKey("[dbo.Defects]", "[Products_ProductsId]", "[dbo.Products]", "[ProductsId]");
        AddForeignKey("[dbo.Defects]", "[Users_UsersId]", "[dbo.Users]", "[UsersId]");
        DropColumn("[dbo.Bundles]", "[Id]");
        DropColumn("[dbo.Defects]", "[Id]");
        DropColumn("[dbo.Defects]", "[ProductId]");
        DropColumn("[dbo.Defects]", "[UserId]");
        DropColumn("[dbo.Products]", "[Id]");
        DropColumn("[dbo.Products]", "[BundleId]");
        DropColumn("[dbo.Users]", "[Id]");
        }

    public override void Down()
        {
        AddColumn("[dbo.Users]", "[Id]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Products]", "[BundleId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Products]", "[Id]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Defects]", "[UserId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Defects]", "[ProductId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Defects]", "[Id]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Bundles]", "[Id]", c => c.Long(nullable: false, identity: true));
        DropForeignKey("[dbo.Defects]", "[Users_UsersId]", "[dbo.Users]");
        DropForeignKey("[dbo.Defects]", "[Products_ProductsId]", "[dbo.Products]");
        DropForeignKey("[dbo.Products]", "[Bundles_BundlesId]", "[dbo.Bundles]");
        DropPrimaryKey("[dbo.Users]");
        DropPrimaryKey("[dbo.Products]");
        DropPrimaryKey("[dbo.Defects]");
        DropPrimaryKey("[dbo.Bundles]");
        DropColumn("[dbo.Users]", "[UsersId]");
        DropColumn("[dbo.Products]", "[BundlesId]");
        DropColumn("[dbo.Products]", "[ProductsId]");
        DropColumn("[dbo.Defects]", "[UsersId]");
        DropColumn("[dbo.Defects]", "[ProductsId]");
        DropColumn("[dbo.Defects]", "[DefectsId]");
        DropColumn("[dbo.Bundles]", "[BundlesId]");
        AddPrimaryKey("[dbo.Users]", "[Id]");
        AddPrimaryKey("[dbo.Products]", "[Id]");
        AddPrimaryKey("[dbo.Defects]", "[Id]");
        AddPrimaryKey("[dbo.Bundles]", "[Id]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_Users_UsersId]", newName: "[IX_User_Id]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_Products_ProductsId]", newName: "[IX_Product_Id]");
        RenameIndex(table: "[dbo.Products]", name: "[IX_Bundles_BundlesId]", newName: "[IX_Bundle_Id]");
        RenameColumn(table: "[dbo.Defects]", name: "[Users]_UsersId]", newName: "[User_Id]");
        RenameColumn(table: "[dbo.Defects]", name: "[Products_ProductsId]", newName: "[Product_Id]");
        RenameColumn(table: "[dbo.Products]", name: "[Bundles_BundlesId]", newName: "[Bundle_Id]");
        AddForeignKey("[dbo.Defects]", "[User_Id]", "[dbo.Users]", "[Id]");
        AddForeignKey("[dbo.Defects]", "[Product_Id]", "[dbo.Products]", "[Id]");
        AddForeignKey("[dbo.Products]", "[Bundle_Id]", "[dbo.Bundles]", "[Id]");
        }

我用括号（“[”和“]]”包围了每个名字，这显然对我的案例中的一些人有所帮助。 我发帖是因为，你猜对了，它不适合我

我总是得到：

参数@objname不明确或声明的@objtype（列）错误

谁能猜出是什么阻止我更新我的数据库？我应该从另一个项目重新开始吗

谢谢

编辑：在注释中指出我的括号放置错误后，我更新为：

不幸的是，这并没有解决我的问题。

我的问题是，出于某种原因，当我运行

Create Migration

时，它生成了一个引用表中不存在的字段的命令。一旦我修好了，它就运行得很好。

你的括号错了。例如，

[dbo.Users]

应该是

[dbo].[Users]

哦，这很有道理，我会试试。谢谢没有运气，没有改变我的问题。谢谢你的努力。你想完成什么？如果您只想基于代码优先模型重建数据库，则不需要迁移-您可以使用DropCreate之类的初始值设定项来完成此操作。。。如果需要同步已部署的数据库，可以使用不同的技术。
