Question

我正在尝试从我的数据库中获取一些必须在一个间隔内开始或结束的数据：

基本的SQL查询如下所示：

SELECT broadcast.id, broadcast.id_channel, broadcast.start_at, broadcast.real_start_at, broadcast.real_end_at, broadcast.title, broadcast.sended, FROM `broadcast` 
WHERE (
    (broadcast.real_start_at >= :p1 AND broadcast.real_start_at <= :p2) 
    OR 
    (broadcast.real_end_at >= :p3 AND broadcast.real_end_at <= :p4)) 
    AND broadcast.sended=:p5 AND broadcast.id_plurimedia=:p6 
LIMIT 50

推进查询就是这个：

$broadcastsQuery = BroadcastQuery::create()
        ->limit(20);
        ->condition('cond1', 'broadcast.real_start_at >= ?', $this->date_start, \Criteria::GREATER_EQUAL)
        ->condition('cond2', 'broadcast.real_start_at <= ?', $this->date_end, \Criteria::LESS_EQUAL)
        ->combine(array('cond1', 'cond2'), \Criteria::LOGICAL_AND, 'cond3')
        ->condition('cond4', 'broadcast.real_end_at >= ?', $this->date_start, \Criteria::GREATER_EQUAL)
        ->condition('cond5', 'broadcast.real_end_at <= ?', $this->date_end, \Criteria::LESS_EQUAL)
        ->combine(array('cond4', 'cond5'), \Criteria::LOGICAL_AND, 'cond6')
        ->where(array('cond3', 'cond6'), null, 'OR');
        ->filterBySended(true)
        ->find();

当我执行我的脚本时，我遇到了这个错误：

Unable to execute SELECT statement [SELECT broadcast.id, broadcast.id_channel, broadcast.id_plurimedia, broadcast.id_aedra, broadcast.start_at, broadcast.real_start_at, broadcast.real_end_at, broadcast.title, broadcast.sended, broadcast.date_creation, broadcast.date_edition FROM `broadcast` WHERE ((broadcast.real_start_at >= :p1 AND broadcast.real_start_at <= :p2) AND (broadcast.real_end_at >= :p3 AND broadcast.real_end_at <= :p4)) AND broadcast.sended=:p5 LIMIT 50] [wrapped: Warning: PDOStatement::bindValue() expects parameter 3 to be long, string given in /var/www/projectKI/vendor/propel/propel1/runtime/lib/connection/DebugPDOStatement.php line 114] (500 Internal Server Error)

我真的不明白为什么我收到错误以及为什么我的查询有“AND”语句而不是“OR”。

Answer 1

我注意到Propel不能做一个简单的＆＃34; OR ＆＃34; （_or（））在2个过滤器之间，包含日期间隔。

它还有Criteria的问题所以我通过用字符串

替换标准来解决我的问题

$broadcastQuery->condition('c1', 'broadcast.real_start_at > ?', $this->date_start)
               ->condition('c2', 'broadcast.real_start_at < ?', $this->date_end)
               ->combine(array('c1', 'c2'), 'and', 'c3')
               ->condition('c1', 'broadcast.real_end_at > ?', $this->date_start)
               ->condition('c2', 'broadcast.real_end_at < ?', $this->date_end)
               ->combine(array('c1', 'c2'), 'and', 'c4')
               ->combine(array('c3', 'c4'), 'or');

在两个过滤器之间推动Symfony2“OR”
