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，我不确定任何人需要哪个部分，这里是github 链接

我已经创建了一个注册表单，并且我已经创建了一个订单表。

当我尝试注册时，我在第二页收到此错误

完整的消息错误是：描述：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源自代码的位置的更多信息。

异常详细信息：System.Data.SqlClient.SqlException：在 SET 子句或 INSERT 的列列表中多次指定列名“phoneNumber”。 在同一个子句中，一列不能分配多个值。 修改子句以确保一列只更新一次。 如果此语句更新或将列插入到视图中，列别名可以隐藏代码中的重复项。

源错误：

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

Answer 1

错误非常明显，您尝试使用插入查询，但在命令中两次指定phone number列：

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

再次查看您的查询，消除双重冲突，它将解决您的问题。

Answer 2

例外情况是，在向表中插入值时，您基本上在SET子句中多次指定了phoneNumber ，即

INSERT INTO TestTable(Id, Name, phoneNumber, Age, phoneNumber)
SELECT * FROM BLABLA

请在Name和Age之后注意double phoneNumber 。

Answer 3

检查您的文件。 同一个人可能在一个记录中有多个输入CRLF。有时人们有多个电话号码，并且可能在CSV文件中用分隔。如果您还算不错，只需按逗号分隔即可。 您的一行中有一个逗号，因此最后一列会重复出现。 查找具有两个数字的人。 另一种方法是将文件分成两个小块，例如10个小文件一个一个地加载，您将看到其中至少一个失败，然后再次将失败的文件拆分并继续这样做。

Answer 4

检查您的数据绑定或映射，您可能会意外地绑定/映射同一列的其他控件或字段。 另一种可能性是您使用相同的变量名来引用控件或字段。 我在任何地方都使用Alpha软件，遇到了同样的问题，并且在修复了数据绑定并更改了变量名后设法解决了该问题。 可能会有一点差异，但根可以相同。 希望这个帮助！

Answer 5

对于 EFCore 6，由于外键列名大小写不正确，我出错了。 当我将“companyid”更改为“CompanyId”时，它已修复。

public int? CompanyId { get; set; }

[ForeignKey("companyid")]
public virtual Company Company { get; set; }
