Question

我的查询有问题，即使我现在发布帖子，TIMESTAMPDIFF也是如此不适用于MINUTE。但是，如果我把DAY或MONTH付诸实施，我真的无法弄清楚可能是什么问题。我的帖子比秒更新。如有任何帮助，将不胜感激

SELECT h2s_job.job_id,
       h2s_job.job_title,
       h2s_job.job_description,
       h2s_job.job_category,
       h2s_job.wantORoffering,
       h2s_job.address,
       h2s_job.cell,
       h2s_job.email,
       h2s_job.date_registered,
       h2s_ad_info.date_registered,
       h2s_job.user_id
FROM h2s_job
INNER JOIN h2s_ad_info ON h2s_job.user_id=h2s_ad_info.user_id
WHERE TIMESTAMPDIFF(MINUTE,h2s_ad_info.date_registered ,NOW())<1

Answer 1

我假设date_registered是TIMESTAMP或DATETIME。如果是这样，你可以这样做：

where NOW() - SECOND(h2s_ad_info.date_registered) < 1

Answer 2

试试这个，

"SELECT TIMESTAMPDIFF(MINUTE, h2s_ad_info.date_registered, now()),
           h2s_job.job_id,
           h2s_job.job_title,
           h2s_job.job_description, 
           h2s_job.job_category,
           h2s_job.wantORoffering,
           h2s_job.address,h2s_job.cell,
           h2s_job.email,
           h2s_job.date_registered,
           h2s_job.user_id 
    From h2s_job
    INNER JOIN h2s_ad_info
    ON  h2s_job.user_id=h2s_ad_info.user_id
    where (TIMESTAMPDIFF(MINUTE, h2s_ad_info.date_registered, now()) < 1)";

这可能对你有所帮助。

我发现了你的问题：它从你插入时间开始：转到你的数据库使date_registered数据类型为datetime：然后使用bellow函数并使用$ date_registered插入你的数据库：更改国家和城市得到正确的时间，因为这是你遇到问题的地方：我确定你的系统上的时间与你原来的不一样。所以针对你的国家和城市

<?php
    # function to get right time 
    date_default_timezone_set('Africa/Johannesburg');
    function time_diff_conv($start, $s)
    {
        $string="";
        $t = array( //suffixes
            'd' => 86400,
            'h' => 3600,
            'm' => 60,
        );
        $s = abs($s - $start);
        foreach($t as $key => &$val) {
            $$key = floor($s/$val);
            $s -= ($$key*$val);
            $string .= ($$key==0) ? '' : $$key . "$key ";
        }
        return $string . $s. 's';
    }

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

# use this if u wanna show day friday like that date('l jS \of F Y \a\t h:i:s A')."\n";
    # function to get right time 
?>

TIMESTAMPDIFF适用于白天，但不适用于分钟
