Update Drupal 8 DB to allow Updates to be run again for testing and dev purposes
When working with Drupal 7 and indeed Drupal 8 we may sometimes need to run updates (hook_update) again. In Drupal 7 updating system table should have been sufficient. In D8 things are a little bit different. Run a database update as follows: SELECT collection, name, substring(value, 1, 2500) FROM key_value WHERE collection="system.schema" and name="modulenameinquestion" The above will give us the last update hook that was run on this database. UPDATE key_value SET value = 'i:9999' where collection="system.schema" and name="modulenameinquestion" Hope this helps.
