Question

我试图在opencart中组合3个查询来构建搜索菜单，但它们总是失败并且出错。

这是示例查询

首先查询：

SELECT p.product_id,
      (SELECT AVG(rating) AS total        
         FROM review r1        
        WHERE r1.product_id = p.product_id        
          AND r1.status = '1'
        GROUP BY r1.product_id) AS rating
  FROM product p       
           LEFT JOIN  product_description pd 
                ON (p.product_id = pd.product_id)
           LEFT JOIN product_to_store p2s 
                ON (p.product_id = p2s.product_id)
 WHERE pd.language_id = '1'       
   AND p.status = '1'       
   AND p.date_available <= NOW()       
   AND p2s.store_id = '0'       
   AND ( LCASE(pd.name) LIKE '%dellxps13%'            
         OR MATCH(pd.tag) AGAINST('dellxps13')           
       )
    OR LCASE(p.model) = 'dellxps13'       
    OR LCASE(p.sku) = 'dellxps13'       
    OR LCASE(p.upc) = 'dellxps13'       
    OR LCASE(p.ean) = 'dellxps13'       
    OR LCASE(p.jan) = 'dellxps13'       
    OR LCASE(p.isbn) = 'dellxps13'       
    OR LCASE(p.mpn) = 'dellxps13'       
 GROUP BY p.product_id       
 ORDER BY p.sort_order ASC, LCASE(pd.name) ASC
 LIMIT 0, 15

第二次查询：

SELECT REPLACE (model," ","") AS 'FIND' 
  FROM product 
 WHERE REPLACE (model," ","")

它已更改为p.model(for innerjoin, p.model = product.model)

第三个查询：

SELECT REPLACE (name," ","") AS 'FIND2' 
  FROM product_description 
 WHERE REPLACE (name," ","")

它已更改为pd.name(for innerjoin, pd.name = product_description.name)。

所以我想首先替换所有，然后select from replace like '%dellxps13%'

任何人都知道如何结合3这个查询？

这是我试图改变并得到错误

AND ((LCASE(SELECT REPLACE (pd.name," ","")) FROM product_description 
WHERE LCASE (REPLACE (pd.name," ",""))) LIKE '%dellxps13%'            
     OR MATCH(pd.tag) AGAINST('dellxps13')           
   )
   OR LCASE((SELECT REPLACE (p.model," ","")) FROM product WHERE LCASE  (REPLACE (p.model," ",""))) = 'dellxps13'

错误1064＆＃39; SELECT REPLACE（pd.name，＆＃34;＆＃34;，＆＃34;＆＃34;））FROM product_description 在哪里LCASE（REPLAC＆＃39;在第16行。

当我不使用LCASE时出错

SELECT p.product_id,
      (SELECT AVG(rating) AS total        
         FROM review r1        
        WHERE r1.product_id = p.product_id        
          AND r1.status = '1'
        GROUP BY r1.product_id) AS rating
  FROM product p       
           LEFT JOIN  product_description pd 
                ON (p.product_id = pd.product_id)
           LEFT JOIN product_to_store p2s 
                ON (p.product_id = p2s.product_id)
 WHERE pd.language_id = '1'       
   AND p.status = '1'       
   AND p.date_available <= NOW()       
   AND p2s.store_id = '0'       
   AND ((SELECT REPLACE (pd.name," ","") FROM pd WHERE REPLACE (pd.name," ","") LIKE '%dellxps13%')         
    OR MATCH(pd.tag) AGAINST('dellxps13'))
    OR (SELECT REPLACE (p.model," ","") FROM p WHERE REPLACE (p.model," ","") LIKE '%dellxps13%')       
    OR LCASE(p.sku) = 'dellxps13'       
    OR LCASE(p.upc) = 'dellxps13'       
    OR LCASE(p.ean) = 'dellxps13'       
    OR LCASE(p.jan) = 'dellxps13'       
    OR LCASE(p.isbn) = 'dellxps13'       
    OR LCASE(p.mpn) = 'dellxps13'       
 GROUP BY p.product_id       
 ORDER BY p.sort_order ASC, LCASE(pd.name) ASC
 LIMIT 0, 15

错误：1146 - 表＆＃39; example.pd＆＃39;不存在

如何在1个查询中组合innerjoin查询和2个替换查询？
