c# - 在 SET 子句中多次指定列名 'phoneNumber'

Question

我正在为我的学生项目创建一个在线咖啡店。

因为它是一个大文件，而且我不确定有人需要哪一部分，这里是 github link

我已经创建了注册表单和订单表。

当我尝试注册时，在第二页出现此错误

完整的消息错误是: 说明:在执行当前 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在代码中的来源的更多信息。

异常详细信息:System.Data.SqlClient.SqlException:在 INSERT 的 SET 子句或列列表中多次指定了列名称“phoneNumber”。在同一子句中不能为一列分配多个值。修改子句以确保列只更新一次。如果此语句更新列或将列插入 View ，列别名可以隐藏代码中的重复项。

来源错误:

第 164 行:
第 165 行:}; 第 166 行:var result = await UserManager.CreateAsync(user, model.Password); 第 167 行:if (result.Succeeded) 第 168 行:{

完整日志如下:

[SqlException (0x80131904): The column name 'phoneNumber' is specified more than once in the SET clause or column list of an INSERT. A column cannot be assigned more than one value in the same clause. Modify the clause to make sure that a column is updated only once. If this statement updates or inserts columns into a view, column aliasing can conceal the duplication in your code.]

Answer 1

错误很明显，您尝试使用插入查询，但在命令中指定了两次 phone number 列:

在 SET 子句或 INSERT 的列列表中多次指定了列名称“phoneNumber”。

再次检查您的查询并消除双重冲突，它将解决您的问题。
