我试图运行查询,但我不能得到正确的输出,我得到了这个错误,我尝试了一些stackoverflow(如。但我无法解决。

这是发生错误的主要代码
if (!empty($data['filter_manufacturer_id'])) {

ON (p.product_id = p2m.product_id)
WHERE p2m.manufacturer_id = '" . (int)$data['filter_manufacturer_id'] . "'";
}
您已经在抛出错误的行附近混合了。将查询更改为如下所示:
SELECT COUNT(DISTINCT p.product_id) AS total
FROM oc_product p
LEFT JOIN oc_product_description pd ON (p.product_id = pd.product_id)
LEFT JOIN oc_product_to_store p2s ON (p.product_id = p2s.product_id)
AND pd.language_id = '1' AND p.status = '1'
AND p.date_available <= NOW() AND p2s.store_id = '0'
LEFT JOIN oc_product_to_manufacturer p2m ON (p.product_id = p2m.product_id)
AND p2m.manufacturer_id = '8'

我的数据库中有两个表,即linkrecord(URL,NAME)和dishrate(dishname,rate,review)。我想创建一个第3个表viz记录,其中包含URL、dishname和评级从第一个两个表,与dishname对应,这是两个表共同的。我尝试了下面的Insert查询,但它显示了错误:“com.MySQL.jdbc.exceptions.jdbc4.mysqlSyntaxerRo
