I've been using Drupal 4.6.5 for a few days creating some nodes.
Today I decided to try 4.7 Beta.
I backuped mySQL database using the EXPORT feature of phpadmin.
I created a test site for my 4.7, created a new database in MYSQL adminstrator from my webhost, updated my settings.php links to that new database and then tried to import my aforementioned backup.
This caused problems:
Firstly, I had to remove the CREATE DATABASE line from the backup file because I got an error message saying the database already existed.
Once removed that line and I imported the file "successfully", the new test site, running 4.7, arrived with errors:
Warning: Unknown column 'referer' in 'field list' query: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (0, 'php', 'Unknown column 'referer' in 'field list'\nquery: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (0, 'page not found', '<em>node</em> not found.', 1, '', '/TEST%20SITE/', '', '67.68.91.182', 1136514718) in /homepages/25/d149789965/htdocs/TEST SITE/includes/database.mysql.inc on line 108.', 2, '', '/TEST%20SITE/', '', '67.68.91.182', 1136514718) in /homepages/25/d149789965/htdocs/TEST SITE/includes/database.mysql.inc on line 108
