MySQL通过时间戳截断小时，分钟和秒来过滤

Question

我已经连接了一个datetimepicker客户端，以根据日期范围过滤结果，但是我无法获得选择的日期选择器日期以包括服务器上的日期。 因此，例如，如果我选择dateTo为2014年11月6日，则结果将不包括该记录，但是如果我选择2014年11月7日，则结果将包括2014年11月6日。我确定这与unixtimestamp有关该服务器包括H：M：S，但我不知道如何截断它们。 我尝试使用DATE_FORMAT甚至使用'％M％d，％Y'的FROM_UNIXTIME，但是返回的范围都不正确，这似乎是迄今为止最接近的范围。

PHP将2014年11月6日（或等效日期）转换为时间戳并附加到SQL查询：

if( !empty($query_filters['dateFrom']) && !empty($query_filters['dateTo']) ) 
{
    $sql .= " AND UNIX_TIMESTAMP(packageinstance.created) 
              BETWEEN " . strtotime($query_filters['dateFrom']) . " 
              AND " . strtotime($query_filters['dateTo']);
}
else if( !empty($query_filters['dateFrom']) && empty($query_filters['dateTo']) ) 
{
    $sql .= " AND UNIX_TIMESTAMP(packageinstance.created) >= " . strtotime($query_filters['dateFrom']);
}
else if( !empty($query_filters['dateTo']) && empty($query_filters['dateFrom']) ) 
{
    $sql .= " AND UNIX_TIMESTAMP(packageinstance.created) <= " . strtotime($query_filters['dateTo']);
}

生成的SQL

SELECT SQL_CALC_FOUND_ROWS 
     packageinstance.id, 
     UNIX_TIMESTAMP(packageinstance.created) as epoch_time, 
     user.username, 
     status.name as status, 
     package.type 
FROM packageinstance 
JOIN user    ON user.id    = packageinstance.creatorid  
JOIN status  ON status.id  = packageinstance.status 
JOIN package ON package.id = packageinstance.packageid 
WHERE packageinstance.locationid = 1 
AND status LIKE '%%' 
AND UNIX_TIMESTAMP(packageinstance.created) < 1415228400 
ORDER BY epoch_time DESC LIMIT 5 OFFSET 0 

我需要做些什么来截断packageinstance.created中此SQL查询中的时间？

UPDATE

使用下面的@alu答案进行PHP日期格式设置，然后添加DATE_FORMAT似乎可行，但这太冗长了吗？ 不能单独使用@alu回答，但这很有帮助。

if( !empty($query_filters['dateFrom']) && !empty($query_filters['dateTo']) ) 
{
    $sql .= " AND DATE_FORMAT(packageinstance.created, '%Y-%m-%d') 
              BETWEEN DATE_FORMAT('" . date('Y-m-d 00:00:00', strtotime($query_filters['dateFrom'])) . "', '%Y-%m-%d')  
              AND DATE_FORMAT('" . date('Y-m-d 00:00:00', strtotime($query_filters['dateTo'])) . "', '%Y-%m-%d')";
}
else if( !empty($query_filters['dateFrom']) && empty($query_filters['dateTo']) ) 
{
    $sql .= " AND DATE_FORMAT(packageinstance.created, '%Y-%m-%d') >= 
              DATE_FORMAT('" . date('Y-m-d 00:00:00', strtotime($query_filters['dateFrom'])) . "', '%Y-%m-%d')";
}
else if( !empty($query_filters['dateTo']) && empty($query_filters['dateFrom']) ) 
{
    $sql .= " AND DATE_FORMAT(packageinstance.created, '%Y-%m-%d') <= 
              DATE_FORMAT('" . date('Y-m-d 00:00:00', strtotime($query_filters['dateTo'])) . "', '%Y-%m-%d')";
}

Answer 1

尝试这个。

 $sql .= " AND packageinstance.created >= '" . date('Y-m-d 00:00:00', strtotime($query_filters['dateFrom'])) . "'";
