Cannot log in.Deleted admin account by mistake

Help!
I have stupidly deleted my admin account and can no longer log in to my website.
I have tried restoring it to a previous date, but that did not seem to work.
I looked in FAQ and found this:

Go to your phpMyAdmin (supplied by your hosting company), click the "SQL" tab and run this query:

DELETE FROM admin WHERE admin_name = 'Admin'; INSERT INTO admin (admin_name, admin_email, admin_pass, admin_level) VALUES ('Admin', 'admin@localhost', '351683ea4e19efe34874b501fdbf9792:9b', 1); "given " query inthe

I got an "error" asking which database.
This is where I stop what I am doing, as I do not want to make matters worse.
The site was built for me so my knowledge is very limited, but can cope if my hand is held !!

Sorry, forget this request above!
Beyond all my expectations, the above has worked. Whoever posted that has been a real life saver. Thank you soooooooooo much. xx
