問題與像在PHP的mysqli

Question

哪些錯誤與此代碼？：

SELECT alias FROM Articls 
WHERE (title LIKE '%key%' 
OR sections LIKE '%key%' 
OR description LIKE '%key%' 
OR category LIKE '%key%' 
OR subcategory LIKE '%key%) 
AND MATCH (content) AGAINST ('key') 
GROUP BY alias ORDER BY alias DESC LIMIT 500 

，但我得到了一個錯誤。所以我簡化代碼這樣：

SELECT alias FROM Articls 
WHERE (title LIKE '%key%' 
OR content LIKE '%key%' 
OR sections LIKE '%key%' 
OR description LIKE '%key%' 
OR category LIKE '%key%' 
OR subcategory LIKE '%key%) 
ORDER BY alias DESC LIMIT 500 

但我仍然得到一個錯誤：

Warning: mysqli_fetch_all() expects parameter 1 to be mysqli_result, boolean given in /home/admin/domains/example.com/public_html/lib/core/p.php on line 141 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''%news%)

Answer 1

您在最後的LIKE語句結尾缺少一個撇號。

SELECT alias FROM Articls 
WHERE (title LIKE '%key%' 
OR content LIKE '%key%' 
OR sections LIKE '%key%' 
OR description LIKE '%key%' 
OR category LIKE '%key%' 
OR subcategory LIKE '%key%') 
ORDER BY alias DESC 
LIMIT 500
