JOIN part_categories pc ON pg.category_id = pc.id
WHERE vp.model_year_engine_id = 1
ORDER BY pc.display_order, pg.display_order;
*/

-- 2. Buscar alternativas aftermarket para una parte OEM
/*
SELECT
    m.name AS fabricante,
    m.quality_tier AS calidad,
    ap.part_number,
    ap.name_es AS nombre,
    ap.price_usd AS precio,

*/

-- 3. Búsqueda full-text de partes
/*
SELECT p.*
FROM parts p
JOIN parts_fts ON p.id = parts_fts.rowid
WHERE parts_fts MATCH 'filtro aceite'
ORDER BY rank;
*/

-- 4. Obtener hotspots de un diagrama con info de partes
/*
SELECT
    dh.callout_number,
    dh.shape,
    dh.coords,
    p.oem_part_number,
    p.name_es AS nombre
FROM diagram_hotspots dh
LEFT JOIN parts p ON dh.part_id = p.id
WHERE dh.diagram_id = 1
ORDER BY dh.callout_number;
*/

-- 5. Buscar por número de parte (incluye cross-references)
/*
SELECT DISTINCT
    p.id,
    p.oem_part_number,
    p.name_es,
    'OEM' AS source
FROM parts p
WHERE p.oem_part_number LIKE '%04152%'
