Question

查詢1子句使用時：

select products 
from buyde_deal 
where displayflag = '1' 
and end_date> now() 
and start_date < now() limit 1 

輸出：

查詢2：

SELECT id,productname ,cat_id ,subcat_id,shortdescription1,shortdescription2,shortdescription3 ,sellingprice,sellpricevat,mrp,regularprice,costprice,sku,qty,pweight,seller_id,shippingcost,color,size,discount 
FROM `buyde_product` 
WHERE id IN ( 
    select products 
    from buyde_deal 
    where displayflag = '1' 
    and end_date> now() 
    and start_date < now()) 
ORDER BY `buyde_product`.`id` " 

輸出：

如果我運行第二個查詢，只返回一條記錄。我需要表1中的所有記錄。

Answer 1

嘗試使用find_in_set：

SELECT id, 
     productname, 
     cat_id, 
     subcat_id, 
     shortdescription1, 
     shortdescription2, 
     shortdescription3, 
     sellingprice, 
     sellpricevat, 
     mrp, 
     regularprice, 
     costprice, 
     sku, 
     qty, 
     pweight, 
     seller_id, 
     shippingcost, 
     color, 
     size, 
     discount 
FROM `buyde_product` 
     JOIN (SELECT products 
      FROM buyde_deal 
      WHERE displayflag = '1' 
        AND end_date > Now() 
        AND start_date < Now()) t 
     ON FIND_IN_SET(`buyde_product`.`id`, t.products) 
ORDER BY `buyde_product`.`id`
