MySQL / MariaDB事务访问冲突1064

我在使用事务查询时遇到了一些麻烦。我有2张桌子, “科目”和链接表调用“tutorsubjects”。我使用的是MariaDB版本10.0.21。我创建了以下查询,但我不断收到“语法错误或访问冲突:1064”错误。

public function addSubject($values){        

    try {
        $temp = $this->db->query("
        BEGIN;
        INSERT INTO subjects
        (subject_code, subject_name, subject_grade, subject_description, subject_category)
        VALUES (:subject_code, :subject_name, :subject_grade, :subject_description, :subject_category);

        SET @last_id = LAST_INSERT_ID();

        INSERT INTO tutorsubject
        (tutor_id , subject_id)
        VALUES (:tutor_id, @last_id);
        COMMIT;",$values);
        return $temp;
    } catch (DBException $e) {
        echo "Error:<br/>" . $e->getMessage();
        return null;
    } catch (Exception $e) {
        echo "Error:<br/>" . $e->getMessage();
        return null;
    }
}

以下是解析为查询的值

$array = array("subject_code" => $code,
    "subject_name" => $subject_name,
    "subject_grade" => $grade,
    "subject_description" => $subject_description,
    "subject_category" => $subject_category, 
    "tutor_id"=>$selecttutor);

我收到以下错误:

  

SQLSTATE [42000]:语法错误或访问冲突:1064 SQL语法中有错误;查看与您的MariaDB服务器版本对应的手册,以便在''reach'附近使用正确的语法。'subject'('subject_code','subject_name','subject_grade','subject_de'在第1行   原始SQL:INSERT INTO'达到'。'subject'('subject_code','subject_name','subject_grade','subject_description','subject_category')VALUES(:subject_code,:subject_name,:subject_grade,:subject_description,:subject_category) ;

我的问题是,当我在phpMyAdmin中运行此查询时,它完成没有任何问题。我正在使用一个发现here的PDO MySQL类作为我的数据库交互的基础。我开始认为也许班级不直接支持交易?

任何想法都会非常感激。

您应该尝试单独保留COMMITBEGIN个查询。

尝试:

 // start the transaction
 $this->db->query("BEGIN;");

 //rest of your queries with db->query() go here
 $this->db->query("INSERT INTO subjects
    (subject_code, subject_name, subject_grade, subject_description, subject_category)
    VALUES (:subject_code, :subject_name, :subject_grade, :subject_description, :subject_category);

    SET @last_id = LAST_INSERT_ID();

    INSERT INTO tutorsubject
    (tutor_id , subject_id)
    VALUES (:tutor_id, @last_id);");

 //commit
 $this->db->query("COMMIT;");

MySQL正在尝试将所有这些作为一个查询执行,并且它不会将整个命令识别为单独的查询。 PhpMyadmin自己将它们分开,这就是它们在那里正确运行的原因。

有些东西是围绕数据库和表名添加撇号。这在语法上是错误的(除非你打开了某个ansi模式)。他们需要是支持者(`)。

尝试让PHP完成工作+使用PDO事务方法,值部分未经测试,因此您需要确保其正确:

$this->db->beginTransaction();

$this->db->query("INSERT INTO subjects
(subject_code, subject_name, subject_grade, subject_description, subject_category)
VALUES (:subject_code, :subject_name, :subject_grade, :subject_description, :subject_category)", $values);

$values['last_id'] = $this->db->lastInsertId();

if (empty($values['last_id'])) {
    $this->db->rollBack();
} else {
    $this->db->query("INSERT INTO tutorsubject
    (tutor_id , subject_id)
    VALUES (:tutor_id, :last_id)", $values);

    $this->db->commit();
}
