Question

我有这个SQL和PHP：

$articles = returndata("
     SELECT 
         (SELECT COUNT(*) from blog_posts) as totalcount,
         (SELECT COUNT(*) from comments where assetid = d.assetid) as replies,
         c.name as categoryname,
         d.category as categoryid,
         d.assetid, 
         d.title,
         d.postdate,
         d.articlecontent
     FROM blog_categories c 
         INNER JOIN 
         blog_posts d 
     GROUP BY d.assetid 
     ORDER BY postdate DESC 
         LIMIT " . (($page - 1) * $size) . ", " . $size
, $database);

我还有一个变量$ query，它包含一个多字查询（比如“hello world”），我想用这个搜索我的数据库。我已经尝试了正确的事情（我认为），但它一直返回0。

试试这个::

SELECT 
(SELECT COUNT(*) from blog_posts) as totalcount, 
(SELECT COUNT(*) from comments where assetid = d.assetid) as replies, 
c.name as categoryname, 
d.category as categoryid, 
d.assetid, 
d.title, 
d.postdate, 
d.articlecontent 
FROM blog_categories c 
INNER JOIN blog_posts d on // join condition
// THE WHERE CLAUSE SHOULD BE HERE LIKE column like '%sample word%'


GROUP BY d.assetid ORDER BY postdate DESC LIMIT

如何将WHERE LIKE放入此SQL SELECT？
