Question

通过向我的MySQL数据库发送multi_query我遇到了问题。我想获取文件的内容并通过多查询将其发送到数据库

我用这个方法创建了一个MySQLi类：

    public function multi_query($resource)
    {   
        $Timer  = microtime(true);
        if($this->MySQLiObj->multi_query($resource))
        {
            do {
                if ($result = $this->MySQLiObj->store_result())
                    $result->free();

                $this->queryCount++;

                if(!$this->MySQLiObj->more_results()){break;}

            } while ($this->MySQLiObj->next_result());      
        }

        $this->SQL[]    = $resource;

        if ($this->MySQLiObj->errno)
        {
            if($this->MySQLiObj->error == true) {
                echo "SQL Error: ".$this->MySQLiObj->error."<br><br>Query Code: ".$resource;
            } else {
                return "SQL Error: ".$this->MySQLiObj->error;
            }
        }
    }

我在这里使用它：

    $mysqli = new \System\Database\MySQLi($_SESSION["server"], $_SESSION["username"], $_SESSION["password"], $_SESSION["database"], $_SESSION["port"]);
    echo $mysqli->multi_query(file_get_contents('install.sql'));

这是我的.sql文件：

SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";


/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;

CREATE TABLE `t_User`
(
    `p_ID` INT(11) UNSIGNED AUTO_INCREMENT,
    `m_Firstname` VARCHAR(75) NOT NULL,
    `m_Surename` VARCHAR(150) NOT NULL,
    `m_Email` VARCHAR(255) NOT NULL UNIQUE,
    `m_Password` VARCHAR(65) NOT NULL,
    `m_ActivationCode` VARCHAR(36) NOT NULL UNIQUE,
    `m_Activated` BIT DEFAULT 0,
    `m_Online` BIT DEFAULT 0,
    `m_LastActivity` DATETIME,
    `m_Birthdate` DATE,
    `m_ProfilPicture` VARCHAR(255),
    `m_SchoolID` INT(11),
    `m_AddressID` INT(11),
    `m_IsAdmin` BIT DEFAULT 0,
    PRIMARY KEY (`p_ID`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

CREATE TABLE `t_School`
(
    `p_ID` INT PRIMARY KEY AUTO_INCREMENT,
    `m_Name` VARCHAR(150) UNIQUE NOT NULL,
    `m_Description` VARCHAR(255),
    `m_Homepage` VARCHAR(150) UNIQUE,
    `m_AddressID` INT,
    `m_ManagerID` INT NOT NULL UNIQUE
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

这是我的错误：

SQL错误：SQL语法中有错误;检查与您的MySQL服务器版本对应的手册，以便在'SET SQL_MODE =“NO_AUTO_VALUE_ON_ZERO”附近使用正确的语法; / *！40101在第1行设置@OLD_CHARACTER_SET_CL'

如果我删除完整的第一行并不重要。我还尝试将文件的内容复制到php变量中......但它也不起作用。

希望有人可以帮助我：/

说到 mysqli_multi_query ，它对我有用：

$q = <<<HERE
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;

CREATE TABLE `t_User`
(
    `p_ID` INT(11) UNSIGNED AUTO_INCREMENT,
    `m_Firstname` VARCHAR(75) NOT NULL,
    `m_Surename` VARCHAR(150) NOT NULL,
    `m_Email` VARCHAR(255) NOT NULL UNIQUE,
    `m_Password` VARCHAR(65) NOT NULL,
    `m_ActivationCode` VARCHAR(36) NOT NULL UNIQUE,
    `m_Activated` BIT DEFAULT 0,
    `m_Online` BIT DEFAULT 0,
    `m_LastActivity` DATETIME,
    `m_Birthdate` DATE,
    `m_ProfilPicture` VARCHAR(255),
    `m_SchoolID` INT(11),
    `m_AddressID` INT(11),
    `m_IsAdmin` BIT DEFAULT 0,
    PRIMARY KEY (`p_ID`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
HERE;

$m = mysqli_connect('localhost','test','aaa','test');
$m->multi_query($q);
var_dump($m->error);

没有引发错误，创建了表格。所以，这个功能显然有效。

MySQLi multi_query不起作用
