Question

我到目前为止能够在zend2 SELECT查询中应用AND和LIKE，但无法弄清楚如何应用OR运算符。这是我的问题：

 $this->table = $data['table'];
    $select = new Select();
    $spec = function (Where $where) {
        $where->like('title', 'border%');
    };
    $select->from($this->table)
            ->where(array('id'=>  8));
    $select->where($spec);
    $resultSet = $this->selectWith($select);
    $resultSet->buffer();
    return $resultSet;

返回此sql语句

SELECT `rs_morning_report`.*   
FROM `rs_morning_report` 
WHERE `id` = :where1 AND `title` LIKE :where2

现在我要添加“AND（扇区LIKE％a％OR sector LIKE％b％）”

Answer 1

您可以使用Where对象链接它们。

$where = new Where();
$where->equalTo('fieldOne', 'XX')
    ->AND
    ->equalTo('field_two', 'XXX')
    ->OR
    ->equalTo('field_three', 'XXX')
;

$select->where($where);

如果需要，您也可以嵌套它们：

$where = new Where();
$where->equalTo('fieldOne', 'XX')
    ->NEST
        ->equalTo('field_two', 'XXX')
        ->OR
        ->equalTo('field_three', 'XXX')
    ->UNNEST
;

$select->where($where);

Answer 2

要生成OR语句，您可以将Zend\Db\Sql\Predicate\PredicateSet与参数PredicateSet::COMBINED_BY_OR一起使用。

示例：

use Zend\Db\Sql\Predicate;

$select->where(array(
    // Other conditions...
    new Predicate\PredicateSet(
        array(
            new Predicate\Like('sector', '%'.$sectorA.'%'),
            new Predicate\Like('sector', '%'.$sectorB.'%'),
        ),
        Predicate\PredicateSet::COMBINED_BY_OR
    ),
));
