问题描述
我正在尝试查找特定用户的时间重叠,我认为我的逻辑会捕获所有时间段,但这仅在开始或结束在时间范围之间时才捕获,但如果两者都是开始和结束,则未找到任何内容在一些记录时间段之间!
I'm trying to find time overlaps of a specific user, I think my logic would catch all over laps, but this catches only if start OR end is in between a time frame but nothing is found if both are start and end are in between some records time period!
$tempModel = clone $this; // clone model
$criteria->addCondition('
( t.user = :user AND (t.startDate >= :start AND t.startDate <= :end ))
OR
( t.user = :user AND (t.endDate >= :start AND t.endDate <= :end ))
');
$criteria->params = array(
':start' => date('Y-m-d', strtotime($tempModel->startDate)),
':end' => date('Y-m-d', strtotime($tempModel->endDate)),
':user ' => $tempModel->userID ,
);
if(!empty($tempModel->idUserTime)) // dont find updated record
$criteria->addCondition('t.idUserTime != ' . $tempModel->idUserTime);
$criteria->addCondition('t.active = 1'); // if this is an active user time
$hasRecord = Usertime::model()->findAll($criteria);
问题出在哪里?
推荐答案
两个日期重叠,如果每个人的边界中至少有一个在另一个边界之间:
Two dates are overlapping, if at least one of each one's boundaies are between the other's boundaries:
...
WHERE some_other_conditions AND (
date1.start BETWEEN date2.start AND date2.end OR
date1.end BETWEEN date2.start AND date2.end OR
date2.start BETWEEN date1.start AND date1.end OR
date2.end BETWEEN date1.start AND date1.end
)
