无法在 AspNetUsers 表中插入用户

Question

我正在尝试使用存储过程填充 AspNetUsers 表，但出现以下错误：

Msg 515，级别 16，状态 2，过程 Insert_Users，第 36 行无法 将值 NULL 插入到"Id"列中，表 'MyDatabase.dbo.AspNetUsers';列不允许空值。插入 失败。

我在其他一些帖子上读到，Id 列上应该有以下属性：[DatabaseGenerated(DatabaseGeneratedOption.Identity)] ，但我无法找到物理声明的位置。

我不想手动插入所有用户，因为我没有时间了，我需要尽快完成。

    IF @athleteKey % 5 = 0
        INSERT INTO [MyDatabase].[dbo].[AspNetUserRoles]
                    (UserId,RoleId) VALUES (@id, 3)
    ELSE
        INSERT INTO [MyDatabase].[dbo].[AspNetUserRoles]
                    (UserId,RoleId) VALUES (@id, 4)
    SET @athleteKey = @athleteKey+1
END

你需要在

WHILE 循环中开始-结束。
否则，它只是不为@id赋值，也不处理循环
