MYSQL同一列中的值比较

时间：2018-10-24 07:26:07

标签： php jquery mysql

我正在尝试在网站上添加高级搜索功能。

目前，一切正常，除了必须在同一列中比较多个值的那一刻

例如，我希望找回所有同时属于神秘客户和调查员类型的候选人。

因此，我第一次在mysql接口中执行此查询，以检查是否已收集所有内容，但仅考虑了第一个条件，所以我只获得类型为mystery customer的候选人：

  

选择*从候选人资格类型为“％mysteryCustomer％”的候选资格和候选人类型为“％investigators％”的候选资格；

所以我做了一些研究，然后遇到了IN运算符。我使用此运算符修改查询。问题是此错误会发回给我：

  

PHP消息：PHP致命错误：未捕获的PDOException：SQLSTATE [42000]：语法错误或访问冲突：1064您的SQL语法有错误。检查与您的MariaDB服务器版本相对应的手册，以获取正确的语法，以在“ WHERE邮政编码IN（“ East”）LIMIT？，？”附近使用在/xxx/xxx/xxx/search.php:106

的第1行

          //index += $(this).closest('div').attr('id');
          data.push($(this).val());
      });

      var nb_per_page = $('.entriesData').val();
      var search = $('#searchContent').val();

您的问题在这一行：

$query = $cnx->prepare("SELECT * FROM candidacies ".$where.$order.$checkbox." LIMIT :start, :nb_per_page");

$order是ORDER BY子句，而$checkbox是WHERE子句，必须在任何ORDER BY子句之前。将该行更改为此，它应该可以正常工作。

$query = $cnx->prepare("SELECT * FROM candidacies ".$where.$checkbox.$order." LIMIT :start, :nb_per_page");
