更新时PDO错误42000

Question

我收到PDO错误信息42000

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id='4'' at line 15

我不知道为什么，当我读到有关此问题的其他问题时，我尝试用反引号转义列和表名，但这没有帮助。

这是我的SQL语句：

private function _update()
{
    $sql = 'UPDATE projects SET
    name=:name,
    client=:client,
    createDate=:createDate,
    timestamp=:timestamp,
    url=:url,
    localUrl=:localUrl,
    budget=:budget,
    payoff=:payoff,
    estimated_time=:estimated_time,
    tasksDuration=:tasksDuration,
    currentStundenlohn=:currentStundenlohn,
    tagPercentage=:tagPercentage,
    tagCategoryPercentage=:tagCategoryPercentage,
    WHERE id=:id';
    $abfrage = self::$db->prepare($sql);
    $abfrage->execute($this->toArray());
    pdo_error($abfrage);
}

你看到可能出现的问题吗？

删除最后一个额外的逗号,。

$sql = 'UPDATE projects SET
    name=:name,
    client=:client,
    createDate=:createDate,
    timestamp=:timestamp,
    url=:url,
    localUrl=:localUrl,
    budget=:budget,
    payoff=:payoff,
    estimated_time=:estimated_time,
    tasksDuration=:tasksDuration,
    currentStundenlohn=:currentStundenlohn,
    tagPercentage=:tagPercentage,
    tagCategoryPercentage=:tagCategoryPercentage // From here
    WHERE id=:id';
