php - MySQL 通过截断小时、分钟和秒来按时间戳进行过滤

Question

我已连接日期时间选择器客户端以根据日期范围过滤结果，但我无法选择日期选择器日期来包含服务器上的日期。例如，如果我选择 dateTo 为 2014 年 11 月 6 日，结果将不包括该记录，但如果我选择 2014 年 11 月 7 日，它将包括 2014 年 11 月 6 日。我确信这与 unixtimestamp 有关服务器包括 H:M:S，但我不知道如何截断它们。我尝试使用 DATE_FORMAT 甚至 FROM_UNIXTIME 使用 '%M %d, %Y'，但是返回的范围都不正确，这似乎是迄今为止最接近的。

PHP 将 2014 年 11 月 6 日(或同等日期)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 

我需要做什么来截断来自 packageinstance.created 的 SQL 查询中的时间？

更新

使用下面的 @alu 答案进行 PHP 日期格式化，然后添加 DATE_FORMAT 这似乎有效，但是相当冗长，这是多余的吗？没有单独使用 @alu 答案，但它很有帮助。

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

试试这个。

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