列名无效。不知道为什么？

Question

最近我将 DateofBirth 添加到表中。在本地，它工作正常。 我还更新了客户的数据库和实体数据模型。但出现错误。

列名“出生日期”无效。 说明：执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

异常详细信息：System.Data.SqlClient.SqlException：列名“出生日期”无效。

Answer 1

表中不存在该列，您必须运行迁移或使用其他方式更新客户数据库

Answer 2

根据堆栈跟踪，我怀疑您在配置类中将 AutomaticMigrationsEnabled 设置为 false。要解决此问题，您需要手动创建一个新的迁移文件。您可以在 Nuget 包管理器控制台中运行 Add-Migration 命令创建新的迁移。

Here is a tutorial on how to create a new migration script.

Answer 3

当我在数据库中更新我的表但尚未在我的界面中的数据绑定或映射中时，我得到了这种错误。在我的数据绑定级别刷新我的数据源后，一切顺利。所以我猜这个错误是由数据库级别和接口级别的数据同步/更新引起的。所以，我要做的就是检查所有的字段控件-列表映射。

Answer 4

确保您的查询有正确的引用。 例如，

cmd.CommandText = "insert into student(id,name,dob) values("+id+","+name+","+dob+")";

是一种编写查询的异常绑定方式。 用这种方法试试

cmd.CommandText = "insert into student(id,name,dob) values('"+id+"','"+name+"','"+dob+"')";
