Question

好的，所以我正在做一个与上传文件和日期有关的项目。我的应用程序允许用户上传文件，他们可以看到他们上传的文件。如果需要，他们可以删除它们。一旦他们认为上传的文件很好，他们就可以完成它，这意味着他们无法删除上传的文件。另外，点击“结束”＆＃39;按钮会将数据库中的状态更改为“已提交”＃39;并加上时间戳。

到目前为止，我发现这两个错误。不知怎的，我在我的SQL中收到了这个错误：

更新leb2。docs AS Doc设置Doc。status =＆＃34;已提交＆＃34;， Doc。datesubmitted = 2015-02-14 14:46:21 在Doc。schoolId = 15

错误：SQLSTATE [42000]：语法错误或访问冲突：1064 SQL语法中有错误;检查与您的MySQL服务器版本相对应的手册，以便在Doc附近使用正确的语法。schoolId = 15＆＃39;在第1行

这些是我的代码：

public function finalize_init(){
        $this->layout = 'school';
        $id = $this->request->params['pass'][0];
        $this->Doc->id = $id;

        $this->Doc->updateAll(array(
            'Doc.status' => '"Submitted"',
            'Doc.datesubmitted' => date('Y-m-d H:i:s')
            ), array(
                'Doc.schoolId'=>$id
                )
        );
        $this->redirect(array('action'=>'documents_init'));
    }

这是我的数据库表：

CREATE TABLE `docs` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `schoolId` int(11) DEFAULT NULL,
  `datesubmitted` datetime DEFAULT NULL,
  `status` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;

我不确定日期的错误是什么。

我希望有人可以帮我解决这个问题。谢谢！

Answer 1

最终查询应该如下所示，

UPDATE leb2.docs AS Doc SET Doc.status = "Submitted",  Doc.datesubmitted = '2015-02-14 14:46:21' WHERE Doc.schoolId = 15;

查询中缺少的是dateubmitted值的qoute

$date = date('Y-m-d H:i:s');

    $this->Doc->updateAll(array(
        'Doc.status' => '"Submitted"',
        'Doc.datesubmitted' => "'{$date}'"
        ), array(
            'Doc.schoolId'=>$id
            )
    );

实现查询， datesubmitted值应该用double qoute和single qoute括起来 “ '{$日期}'”
