I'm using DNN 4.9.5. I have two users I'm trying to delete and every time I try I get the following error message "Can't Delete User". I've search the forum looking for a SQL script or any other method of doing so. I haven't found anything that works or that I understand much of. I have a site that I've been testing and it's ready for launch. But I would like to rid the two test users before doing so. Any help would do.

Note: I've had other users that I could deleted OK. I'm not a DB expert so I'm VERY leery of l assessing the database directly.

Thanks

Are you trying to hard delete or soft delete the users? If it's a soft delete I'm pretty sure you cannot delete either the Admin or Host account. And you must have at least one Admin account per site from what I understand.

If you are looking for a hard delete (purging them from the database directly). Then the following script will remove them from the database. You must run it from inside your DNN installation and not the SQL server directly.

Hard Delete User Script

//Since DNN can only soft delete users you'll have to run the follow script to ensure that all user data is hard deleted from the database
//You must run the script from the HOST MENU through DNN and not from sQLserver directly
//The script will only delete one user at time, you will have to keep executing it until all users have been deleted

delete {databaseOwner}{objectQualifier}userroles where userid=(select top 1 userid from {databaseOwner}{objectQualifier}userportals where isdeleted=1 and userid not in (select userid from {databaseOwner}{objectQualifier}userportals where isdeleted=0))
delete {databaseOwner}{objectQualifier}userprofile where userid=(select top 1 userid from {databaseOwner}{objectQualifier}userportals where isdeleted=1 and userid not in (select userid from {databaseOwner}{objectQualifier}userportals where isdeleted=0))
delete aspnet_membership where userid=( select userid from aspnet_users where username=(select username from {databaseOwner}{objectQualifier}users where userid=(select top 1 userid from {databaseOwner}{objectQualifier}userportals where isdeleted=1 and userid not in (select userid from {databaseOwner}{objectQualifier}userportals where isdeleted=0))))
delete aspnet_users where username=(select username from {databaseOwner}{objectQualifier}users where userid=(select top 1 userid from {databaseOwner}{objectQualifier}userportals where isdeleted=1 and userid not in (select userid from {databaseOwner}{objectQualifier}userportals where isdeleted=0)))
delete {databaseOwner}{objectQualifier}userportals where userid=(select top 1 userid from {databaseOwner}{objectQualifier}userportals where isdeleted=1 and userid not in (select userid from {databaseOwner}{objectQualifier}userportals where isdeleted=0))
delete {databaseOwner}{objectQualifier}users where userid not in (select userid from {databaseOwner}{objectQualifier}userportals) and issuperuser=0

My guess is that those users have inserted data into a table that has a foreign key on the users table.  Have you looked in the EventLog to see if there is any more information stored on the error?

Overall, a SQL delete is not recommended as there are multiple tables that you have to modify.

How do I find out what tables the users are linked to? I would like to get ride of them. The event log shows no errors.
