Upgrade from 1.9 to 2.2 fails due to 'display' column problem



    • Affected Branches:


      When upgrading form 1.9 to 2.2, I got the following problem in the web interface:

      Error reading from database
      Debug info: Unknown column 'display' in 'field list'
      SELECT id, name, display, displayoptions, tobemigrated, revision FROM mdl_resource WHERE id = ?
      [array (
      0 => '250',

      After doing a google search on that, it seems that it affected other users too who originally installed from a Moodle versions before 1.9. I moved some modules out of the way to try to determine if it one of those affected the part of the upgrade, and then the upgrade seemed to have just completed and after moving the modules back it didn't complain either (I'm pretty sure that's not the right way to deal with this).

      It would be ideal if the upgrade scripts could detect this problem and fix it instead of just giving up.
