I was wondering what could be the solution by adding userId in table Articles
We could do this if we want to show articles of a particular User for exemple

I know we have the AddedBy but its only a string of the username.

My problem is that UserId is a Guid and im very not sure how to implement this on the BizObject and on all the related Classes like ArticlesDetails and ArticlesProvider and Articles.cs and so on... also the DataReader...
Like is it a string ??? can we compare the uniqueidentifier as a string... :/


Any help ???

Thanks !

First, username is unique so you can use to locate all articles of specific user.

Second, in your objects you use GUID structure as your type.
And you can can ToString() it if you like.
