Error acceso 404 wp-admin

Regards!

I can not access the desktop of my site. The wp-admin link gives a 404 error.

Activate the debug in wp-config to show errors and boot this:

WordPress database error: [Unknown column ‘url’ in ‘where clause’]
SELECT count (*) FROM wp_datalist WHEREurl = “/ wp-admin /”

I have made many attempts to fix this problem, specifically those described in this post:

Without none give result.

I do not have a backup to restore.

Can someone help me or know what I can do?

Thanks in advance 🙂
