For a specific module, how can I check which database updates have been applied in Drupal 9? I've downloaded a database from a server and I want to check what the current module schema is.

In Drupal 7, this was in the system database table, but that no longer exists.

For Drupal 9.3+/10:

drush php-eval "echo \Drupal::service('update.update_hook_registry')->getInstalledVersion('mymodule');"

Source: Change record

For Drupal 8/9 up to 9.3:

drush php-eval "echo drupal_get_installed_schema_version('mymodule');"

Source: gist

  • Check the API documentation - drupal_get_installed_schema_version() is deprecated in Drupal 9 and will be removed in Drupal 10. If you use the recommended replacement now, you won't have to make any changes to this code in the future.
