We're having a little trouble selecting the proper database for WordPress.
Are you sure it exists?
Your database name is currently specified as techenig_wordpress. Is this correct?
On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?
I get this error when I load up my wordpress page. Any idea why? how do I get this running. BTW I have no MySQL, or PHP knowledge whatsoever so I'm not sure if I setup the table correctly. But how do I fix this and I'll worry about that when I come to it?
