不能在AspNetUsers表

Question

我试图使用存储过程来填充AspNetUsers表中插入用户，但我得到以下错误：

Msg 515, Level 16, State 2, Procedure Insert_Users, Line 36 Cannot insert the value NULL into column 'Id', table 'MyDatabase.dbo.AspNetUsers'; column does not allow nulls. INSERT fails.

我读了一些其他职位，应该有以下属性列Id：[DatabaseGenerated(DatabaseGeneratedOption.Identity)]，但我无法找到实际声明的位置。

我不想手动插入所有用户，因为我没时间了，我需要尽快完成。

WHILE @athleteKey < @atheletsCount 
    SET @id = NEWID() --Line 36 
    print CAST(@id AS nvarchar(128)) 
    SET @fname = (SELECT FirstName FROM [BIBD].[dbo].[Athlete] where AthleteKey=@athleteKey)

    SET @username = CONCAT(LOWER(@fname),'.',LOWER(@lname)) 
    SET @email = CONCAT(LOWER(@fname), '.', LOWER(@lname), '@gmail.com')

      ,@lname) 

    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

在WHILE循环中需要BEGIN-END。
否则它只是不分配值给@id并且不处理循环
