我在mvc视图中有一个表单，其中包含名称、用户名、电子邮件地址、分支机构和部门的下拉列表。有两个存储过程正在检查重复的用户名和电子邮件地址。如果用户单击更新按钮，将显示错误

情景1

如果用户删除用户名并输入唯一的用户名，则表单将不会提交，因为数据库中仍然存在电子邮件地址

如果用户返回原始用户名，我如何允许更新继续

将旧值（仅用户名和电子邮件）与新值进行比较，如果它们相同，则不检查以前是否存在。如果它们不同，则检查新的是否唯一

如果电子邮件是'user1@example.com，username='user1'

然后他输入了电子邮件user1@eample.com'但用户名='user1updated'

您首先检查旧电子邮件和新电子邮件（两者都是'user1@example’）那就好了。然后用新用户名检查旧用户名（此处不同），因此我检查数据库中是否存在新用户名（“user1updated”），如果没有，我会更新，否则不更新
