However not all objects that use this structure may have their own object table and since multiple of the same type of objects could be created that use the same strucuture, there is a need for unique structure_object_id. Additionally if structure_object_id was not there and for example nexus_menu was referring directly to structure_id, it would have created a problem when menu is deleted as then you have to specifically check if there are any other menus using the same structure before deleting from tiki_structure_objects table''

| +Below is SQL code to retrieve data for list of items in the structure when its id is specified as STRUCTURE-ID. It shows that it still can be done with one database operation just like it was for single item tables (such as nexus_menu_items or tiki_blog_posts): |

| +SELECT tiki_structure_item.structure_item_id, tiki_structure_item.item_type, tiki_structure_item.item_id, tiki_structure_item.url, tiki_structure_item.name, tiki_structure_item.description, tiki_structure_item_position.pos, tiki_structure_item_position.parent_id FROM tiki_structure_item, tiki_structure_item_position WHERE tiki_structure_item_position.stucture_item_id = tiki_structure.structure_item_id AND tiki_structure_item_position.structure_id = STRUCTURE-ID ORDER BY tiki_structure_item_position.pos |
