Question

我已将站点从具有mysql服务器的服务器迁移到了具有MariaDB服务器版本的其他站点，并且该站点在旧服务器上正常运行

但是在新版本中，我收到此错误：

1064您的SQL语法有错误；检查手册对应于您的MariaDB服务器版本，以使用正确的语法位于“ #__whmportfolio_item行来自{4）的行中”附近第1行

这是该模块的辅助代码：

<?php

    class ModWhmPortfolioHelper
    {
        public static function toggleVoteAjax() {
        $db = JFactory::getDbo();
        $u = WhmportfolioFrontendHelper::getUid();
        $pfid = JRequest::getInt('pfid', 0);
        if(!$pfid) {
            return null;
        }
        $rs = $db
        ->setQuery("SELECT id FROM #__whmportfolio_liked WHERE u = '{$u}'")
        ->loadObject();
        if(is_null($rs)) {
            $db

        }
        else {

        return $db

        ->loadObject()->c;
    }

    }


    }

Answer 1

#引入了一个注释，该注释一直持续到行尾。

要在表名中使用#，请使用反引号将其引号：

  ->setQuery("DELETE FROM `#__whmportfolio_liked` WHERE id = {$rs->id}")
                          ^                     ^

第1行“（＃4）中的行来自## whmportfolio_item`行附近的语法错误”
