Mysql的子查詢結果在where子句中

Question

我試圖讓子查詢銷售的結果，並在WHERE子句中使用它... 我要排除銷售額等於1

是否有一個如何做到這一點？

SELECT 
    p.product_id, 
    etp_vendor.active, 
    (SELECT AVG(rating) AS total FROM etp_review r1 WHERE r1.product_id = p.product_id AND r1.`status` = '1' GROUP BY r1.product_id) AS rating, 
    (SELECT etp_category.sale FROM etp_category WHERE etp_category.category_id = etp_product_to_category.category_id ORDER BY etp_category.sale LIMIT 1) AS sales, 
    (SELECT pd2.price FROM etp_product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '1' AND pd2.quantity = '1' AND (pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW()) ORDER BY pd2.priority, pd2.price LIMIT 1) AS discount, 
    (SELECT ps.price FROM etp_product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '1' AND (ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW()) ORDER BY ps.priority, ps.price LIMIT 1) AS special 
FROM 
    etp_product p 
    LEFT OUTER JOIN etp_product_description pd ON (p.product_id = pd.product_id) 
    LEFT OUTER JOIN etp_product_to_store p2s ON (p.product_id = p2s.product_id) 
    INNER JOIN etp_product_to_vendor ON (p.product_id = etp_product_to_vendor.product_id) 
    INNER JOIN etp_product_to_category ON (p.product_id = etp_product_to_category.product_id) 
    INNER JOIN etp_vendor ON (etp_product_to_vendor.vendor_id = etp_vendor.vendor_id) 
WHERE 
    pd.language_id = '1' AND 
    p.`status` = '1' AND 
    etp_vendor.active = '1' AND 
    p.date_available <= NOW() AND 
    p2s.store_id = '0' 
GROUP BY 
    p.product_id 
ORDER BY 
    p.sort_order, 
    LCASE(pd.name)

是的，你可以使用HAVING條款

GROUP BY 
    p.product_id 
HAVING sales != 1 /* or HAVING sales <> 1*/ 
ORDER BY 
    p.sort_order, 
    LCASE(pd.name)
