Delete DNN users permanently and reset the next userID

Hello,

I have some text DNN users on my DNN users table. I created those users as registered DNN users. I want to delete these users permanently apart from the superuser. But my problem is when I delete these users, then the next new users' userIds are starting from the last userId even we delete the users permanently. The userId should be the next userId after the superuser. How can I do this?

Please, can you advise me?Thank you very much.

I know this is an old post but I'm wondering how to do the same thing. Did you figure this out or does anyone have a solution?

You'll want to read about T-SQL identity seeds

I don't know that I would recommend it, but you could give it a shot.

Re: Delete DNN users permanently and reset the next userID

Well, in my eyes, an ID is just an ID, you should not take care about that. An ID is not suitable to pack any information in it, nor to read anything out of it.

When you have 10 users with the IDs 1 to 10, and you delete the user with the ID 8, the next user you insert may have the ID 11 (or maybe 1011, when you restart the server in the meantime, as it is based on an identity seed and not on a sequence). Therefore it does not say anything, and it does not matter in any way (you do not have 11 nor do you have 1011 users, but 10 - the user ID is meaningless in terms of containing information).

And I would not recommend to play around with identity seeds in a production environment.

Happy DNNing!
