Scrivi sottoquery per ottenere i totali dei clic e delle vendite per ciascun annuncio nell'intervallo di date. Unisciti a questi con l'ad tabella per ottenere il nome dell'annuncio e il product tabella per ottenere i nomi dei prodotti. Combina i nomi dei prodotti usando GROUP_CONCAT .
SELECT ad.ad_name, IFNULL(clicks, 0) AS clicks, IFNULL(product_sale, 0) AS product_sale, IFNULL(GROUP_CONCAT(DISTINCT p.product_name), '') AS products
