Code:
SELECT DISTINCT
items.id,
items.name,
items.bagtype
FROM
tradeskill_recipe_entries
INNER JOIN tradeskill_recipe ON tradeskill_recipe.id = tradeskill_recipe_entries.recipe_id
INNER JOIN items ON tradeskill_recipe_entries.item_id = items.id
WHERE
tradeskill = 58
AND tradeskill_recipe_entries.iscontainer = 1;
The above query will allow you to select any containers that are part of a Research Combine DB-wide. Maybe it could help some people who may not know how to grab them from DB to do the suggested change.
