For the benefit of those who find this thread in the future: Manually manipulating information in the database is a horrible idea.
If you want to revert an accidental marking of everything as read, you can just set the view mode to all articles or use the dedicated (virtual) feed "Recently read" to see what's been marked read, then select all and toggle the selection(s) back to unread.
All that being said, NGPriest, you literally deleted raw information from the database. You can't get that information back. If you have a backup you can restore it, otherwise you're out of luck. The ttrss_user_entries table contains meta data; it is linked to the ttrss_entries table by ID and reconstructing that data manually would be tedious to say the least.
