Insert into List(Text) Field
===

I have a Drupal content type that includes Zip Codes (Postal Codes).  An unlimited number of Zip Codes is allowed, and the Zip Codes are defined in the "**Allowed Values List**" in the field definition.  I have many Zip Codes that I need to insert, and have them staged them and their relationship to nodes in a temporary database table.

I do the following insert to both "**field_data_field_zip_codes**" and "**field_revision_field_zip_codes**", but I still do not see the values in the online Content.  

Has someone done this type of thing before, and know what I am missing?  I looked at using "Feeds" but that module doesn't seem to support multi-value fields, just flat tables.

    INSERT INTO  field_revision_field_wp_zip_codes
    SELECT c.entity_type                     AS entity_type
          ,'wp_content_component'            AS bundle
          ,0                                 AS deleted
          ,c.entity_id                       AS entity_id
          ,c.entity_id                       AS revision_id
          ,'und'                             AS language
          ,(@rownum:=@rownum+1) - 1          AS delta
          ,z.zip                             AS field_wp_zip_codes_value
    FROM field_data_field_wp_cc_id c 
      INNER JOIN cc_zips z 
         ON z.cc = c.field_wp_cc_id_value,
         (SELECT @rownum:=0) r
     WHERE z.cc = '1039'
     AND c.entity_id = '3699';
