每次插入电子邮件和密码时都会出现此错误：

无法在具有唯一索引“aspnet\u Users\u index”的对象“dbo.aspnet\u Users”中插入重复的键行。重复的键值为（f12020b5-6b40-488a-bc55-2bb4708986b2，）。违反主键约束“PK__aspnet_M__1788CC4DA6E8A466”。无法在对象“dbo.aspnet_成员身份”中插入重复密钥。重复的键值为（556ba324-9720-4081-a4be-89fbb38902fc）。违反主键约束“PK__aspnet___AF2760AD5013D67A”。无法在对象“dbo.aspnet\u UsersInRoles”中插入重复键。重复的键值为（556ba324-9720-4081-a4be-89fbb38902fc、084b9f2d-08d4-4e74-911e-ac5ae50dfaf9）。声明已终止。声明已终止。声明已终止

将distinct添加到select语句

  SELECT DISTINCT  @USERID, -- UserId - uniqueidentifier
                   RoleId -- RoleId - uniqueidentifier
  FROM dbo.aspnet_Roles WHERE RoleName IN ('Empresas')

---

您可以检查@USERID是否为NULL，这很好。但在

ELSE

（即

@USERID不是null

）部分中，您尝试再次插入。这是您违反PK的行为。

“无法插入重复密钥”似乎不言自明。您在理解哪一部分时遇到困难？问题是，该过程在没有将用户名和电子邮件添加到aspnet_成员表的情况下插入数据库
