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 …

当列是创建的别名时,我无法弄清楚为什么我会得到一个未知列.任何帮助都会很棒.

码:

SELECT DISTINCT 
    c.id, 
    ((SUM(c.width_feet)*12)+(SUM(c.width_inches))) AS width, 
    ((SUM(c.height_feet)*12)+(SUM(c.height_inches))) AS height 
    FROM carpets AS c 
    WHERE c.active = '1' 
    AND (width BETWEEN '0' AND '275') 
    AND (height BETWEEN '0' AND '599') 
    ORDER BY c.item_no 

错误:

'where子句'中的未知列'width'
