MySQL查询在phpmyadmin中工作,但不能通过php

Question

任何想法都会有所帮助,我现在已经有一段时间了,只是无法弄清楚出了什么问题.

问题:查询工作正常,直到我在多字搜索中添加,您可以在下面看到粗体.但是,我回应了sql查询,然后粘贴在phpmyadmin,它工作得很好,但通过PHP它得到0记录.它没有任何意义,我无法弄清楚可能导致0结果的原因.

SELECT 
        DISTINCT c.id 
    FROM 
        carpets AS c 
        INNER JOIN carpet_relations AS r1 ON c.id = r1.carpet_id 
        INNER JOIN carpet_relations AS r2 ON c.id = r2.carpet_id
        INNER JOIN carpet_relations AS r3 ON c.id = r3.carpet_id
    WHERE 
        c.active = '1' 



        AND ((c.title LIKE '%north tabriz%') OR **(c.title LIKE '%north%') OR (c.title LIKE '%tabriz%')** OR (c.item_no LIKE '%north tabriz%') OR **(c.item_no LIKE '%north%') OR (c.item_no LIKE '%tabriz%')** OR (c.pattern LIKE '%north tabriz%') OR **(c.pattern LIKE '%north%') OR (c.pattern LIKE '%tabriz%')** OR (c.period LIKE '%north tabriz%') OR **(c.period LIKE '%north%') OR (c.period LIKE '%tabriz%')** OR (c.country LIKE '%north tabriz%') **OR (c.country LIKE '%north%') OR (c.country LIKE '%tabriz%')**)

        AND (c.width_feet BETWEEN '0' AND '22') 
        AND (c.width_inches BETWEEN '0' AND '11') 
        AND (c.height_feet BETWEEN '0' AND '49') 
        AND (c.height_inches BETWEEN '0' AND '11')

尝试这个：

SELECT 
    DISTINCT c.id 
FROM 
    carpets AS c 
    INNER JOIN carpet_relations AS r1 ON c.id = r1.carpet_id 
    INNER JOIN carpet_relations AS r2 ON c.id = r2.carpet_id
    INNER JOIN carpet_relations AS r3 ON c.id = r3.carpet_id
WHERE 
    c.active = '1' 

    AND ((c.title LIKE '%north%')
   OR (c.title LIKE '%tabriz%')
   OR (c.item_no LIKE '%north%')
   OR (c.item_no LIKE '%tabriz%')
   OR (c.pattern LIKE '%north%')
   OR (c.pattern LIKE '%tabriz%')
   OR (c.period LIKE '%north%')
   OR (c.period LIKE '%tabriz%') 
   OR (c.country LIKE '%north%')
   OR (c.country LIKE '%tabriz%'))

    AND (c.width_feet BETWEEN 0 AND 22) 
    AND (c.width_inches BETWEEN 0 AND 11) 
    AND (c.height_feet BETWEEN 0 AND 49) 
    AND (c.height_inches BETWEEN 0 AND 11) 
ORDER BY 
    c.item_no

我删除了“LIKE '%north tabriz%'”部分，因为它们是多余的，因为如果它单独匹配“north tabriz”，那么“north”和“tabriz”也将是正确的。

另外，我去掉了子句之间数字周围的单引号。

无法重现表格来测试它，因为您只显示了 1 个表格，但希望这会有所帮助。
