It sounds like your problem is that you have delete a field on your node, which makes Drupal rename the table storing the field data to field_deleted_data_ID. The error you are getting is that one of such tables is missing, and the delete fails since the query to delete the data creates a SQL error.

I know of two ways to solve this.

  • Recreate the table deleted.
  • Delete the field info from field_config and possibly field_config_instance.
  • I'm running into this problem months after the delete happened without knowing the details around that delete event. Any sense what the sql would be to recreate the table? It seems this would work, but what IS a working structure that could make Drupal happy again. Regarding deleting the field info from those two tables...how would you figure out which field? – greggles Dec 14 '12 at 17:47

    @greggles deleted fields have deleted = 1 in field_config – googletorp Dec 14 '12 at 23:15
  • So, interestingly enough I have records in field_config and field_config_instance that both look like partially deleted data. BUT...the field_names in one don't match the field_names in the other. Is that somewhat to be expected? Thanks for your help! – greggles Feb 20 '13 at 19:13
