php - 在 PHP 中选择 MySQL 时出现问题

Question

我收到此错误:

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 'and idcat = 00 OR idcat = 11 OR idcat = 4 OR idcat = 8 OR idcat = 10 OR idcat ' at line 6

我尝试在 PHP 上执行此查询

SELECT *,
        MATCH (name,description) AGAINST ('key') AS relevancia
  FROM offer
  WHERE
      MATCH (name,description)
          and idcat = 00
          OR idcat = 11
          OR idcat = 4
          OR idcat = 8
          OR idcat = 10
          OR idcat = 5
          OR idcat = 7
          OR idcat = 1
          OR idcat = 2
          OR idcat = 3
          OR idcat = 6
          OR idcat = 9
      AGAINST ('key')
  ORDER BY discount DESC
  LIMIT 0, 15

但是如果我尝试直接在 phpmyadmin 上执行此查询，它就可以正常工作。所以我不知道为什么如果同样的咨询在 PHP 上不起作用。

顺便请原谅我糟糕的英语。

编辑:

这是 php 控制台

$sql2 = "SELECT *, 
MATCH (name,description) 
AGAINST ('$search')
AS relevancia 
FROM offer 
WHERE MATCH (name,description) AGAINST ('$search')  
and  $wheres $order $limit";

echo $sql2;
mysql_query("".$sql2."")  or die (mysql_error());

$sql2 上的 php 结果

SELECT *, MATCH (name,description) AGAINST ('key') AS relevancia 
FROM offer 
WHERE MATCH (name,description) AGAINST ('key') 
and idcat IN(00, 11, 4, 8, 10, 5, 7, 1, 2, 3, 6, 9) 
ORDER BY discount DESC LIMIT 0, 3

php-mysql 错误

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
'idcat IN(00, 11, 4, 8, 10, 5, 7, 1, 2, 3, 6, 9) ORDER BY discount DESC' at line 5

Answer 1

试试这个:

SELECT *, concat (name, relevance) AS relevancia 
FROM offer 
WHERE MATCH (name,description) AGAINST  ('key') 
and (idcat = '00' 
OR (idcat > 0 
and idcat<=11))
ORDER BY discount DESC LIMIT 0, 15
