为什么要使用sprintf（）??

$query = "SELECT 
    p.id as ID,
    sk.meta_value AS SKU,
    p.post_title AS PRODUTO,
    pc.meta_value AS PRECO,
    ap.meta_value AS APLICACAO,
    fb.meta_value AS FABRICANTE,
    ct.name AS CATEGORIA,
    im2.meta_value AS IMAGEM
FROM wp_posts p

INNER JOIN wp_postmeta pr ON (
    p.ID = pr.post_id AND
    p.post_type = 'product' AND
    p.post_title like '%".$busca."%'
)

    p.ID = es.post_id AND
    es.meta_key = '_stock'

LEFT JOIN wp_postmeta im1 ON (

    im1.meta_value IS NOT NULL AND
