数据库查询不同结果
原标题:Database query different results

我在编辑我的 Magento 仓库时遇到了一个新问题。 问题是 PHP & amp; MySQL 与Magento 相关, 而不是与 Magento 相关, 因为我尝试了使用处理数据库的原始 PHP 代码, 而不是 Magento 处理者和帮手 。

$a = "Tapet colectia Alice Whow C";

$sql = "
  SELECT *
  FROM `catalog_product_entity_varchar`
  WHERE `value` LIKE  %".$a."% 
  LIMIT 0, 30
";

当我搜索 $a 变量 Im 获得 0 结果时,但当我搜索变量 s 值 < code> Tapet coectia Alice Wow C 时,我得到了预期结果。

为什么会发生这种事?

问题回答

所以,你在给Magento数据库打电话,嗯?

require_once  /path/to/app/Mage.php ;
Mage::app();

$db = Mage::getSingleton( core/resource )->getConnection( core_read );
$a =  Tapet colectia Alice Whow C ;
$select = $db->select()
             ->from( catalog_product_entity_varchar )
             ->where($db->quoteIdentifier( value ) .   LIKE ? , "%{$a}%");
$result = $db->fetchAll($select);
echo count($result);
