Hey guys

I get the following error, when I enable the rdf module in the core:

Error messagePDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'drupal7_test2.rdf_mapping' doesn't exist: SELECT mapping AS mapping FROM {rdf_mapping} rdf_mapping WHERE (type = :db_condition_placeholder_0) AND (bundle = :db_condition_placeholder_1) ; Array ( [:db_condition_placeholder_0] => comment [:db_condition_placeholder_1] => comment_node_wlanap ) in _rdf_mapping_load() (line 197 of /var/www/drupal7/modules/rdf/rdf.module).

I'm using drupal 7.2.
Does anyone have a suggestion to solve this problem?
Regards
Philip

It sounds like the rdf_mapping table was deleted manually, so it needs to be created again. Try completely uninstalling the rdf module and then reinstalling it.

How can I reinstall this module? I mean it's in the core... xD Do you maybe know which update creates this table? I made an upgrade from Drupel 6.14 to 7.2 and in the Database from the 6.14 version there is no table called "rdf_mapping".

You can uninstall core modules in the same way you uninstall contrib modules.

I tested this out on my local copy and I would recommend also deleting the rdf module entry from the system table. In system, search for name='rdf' and then delete the row. Then when you enable rdf module, it will create the table.

@Higarigh can you confirm that you had the contributed rdf module installed in Drupal 6 before upgrading to Drupal 7?

I had the contrib module installed and got this issue. in addition to manually deleting the module from the system table, I also had to manually empty the cache and the cache_bootstrap tables to get past this error...

I had the rdf module installed in a Drupal 6 site, upgraded the site to Drupal 7, and ran into this problem when I tried to install the schema.org module which requires rdf . I was able to get the site working again by removing the rdf module directory from the Drupal 7 core modules directory, and removing the rdf row from the system table as suggested here. Thanks! After that I got another copy of the rdf module, placed it in the core modules directory, and turned on the rdf module again, and everything is working again. Yes joy.
