我想添加我的请求的括号，但我不知道如何添加。你能帮助我吗 ？ 我的 SQL 查询：
SELECT *
FROM vw_my_asn_header
WHERE username = 'toto'
AND (shipment_number LIKE '20151106052811' OR
shipment_number LIKE '20151110053250' OR
shipment_number LIKE '20151116054359')
ORDER BY message_id ASC
我的功能：
public function searchSitesDeliveries($username, Search $search)
{
$select = $this->tableGateway->getSql()->select();
array(new Predicate\Expression('username = ?', $username)),Predicate\PredicateSet::COMBINED_BY_AND);
if (!empty($search->get_shipment_number()))
{
$valeur = $search->get_shipment_number();
if(is_array($valeur))
{
$valeur = array_unique($valeur);
foreach ($valeur as $key => $value)
{
if($key == 0)
{
$predicate_set->andPredicate(new Predicate\Expression('shipment_number IN', '%'.$value.'%'));
$predicate_set->nest();
$bool = true;
}
else
{
$predicate_set->orPredicate(new Predicate\Like('shipment_number', '%'.$value.'%'));
}
}
if($bool == true)
{
$predicate_set->unnest();
}
}
else {
$predicate_set->andPredicate(new Predicate\Like('shipment_number', '%'.$valeur.'%'));
}
}
$select->where($predicate_set);
$resultSet = $this->tableGateway->selectWith($select);
return $resultSet;
}
$predicate_set->nest；给我带来下一个错误：
`Call to undefined method Zend\Db\Sql\Predicate\PredicateSet::nest()`
在文件的开头，我：

有什么问题吗？
谢谢你
我写了一个测试：
public function searchSitesDeliveries($username, Search $search)
{
if (!empty($search->get_shipment_number()))
{
$valeur = $search->get_shipment_number();
if(is_array($valeur))
{
$toto = array();
$valeur = array_unique($valeur);
$select = $this->tableGateway->getSql()->select();
$titi = "$" ;
$compteur = 0;
foreach ($valeur as $key => $value)
{
$toto[$compteur] = $value;
$compteur = $compteur + 1;
}
for ($i=0; $i < ($compteur); $i++) {
\Zend\Debug\Debug::dump($toto[$i]);
if($i== 0 || $i == $compteur )
{
$titi = $titi . "select->where->equalTo('user_name', '".$username."')->next->like('shipment_number','".$toto[$i]."')";
}
else
{
$titi = $titi . "->or->like('shipment_number','".$toto[$i]."')->unnest;";
}
}
\Zend\Debug\Debug::dump($titi);
$resultSet = $this->tableGateway->selectWith(eval($titi));
}
}
return $resultSet;
}
但是：
string(173) "$select->where->equalTo('user_name', 'toto')->next->like('shipment_number','20151125056269')->or->like('shipment_number','20151014048501')->unnest;"
和 :
Message error : Not nested
这个例子更简单
$select->where->equalTo('user_name', $userName)
->nest()
->like('shipment_number', '20151106052811')
->or
->like('shipment_number', '20151110053250')
->or
->like('shipment_number', '20151116054359')
->unnest()
如果你想使用
Predicate$predicate = new Predicate\PredicateSet(
[
new Predicate\Operator('user_name', Predicate\Operator::OPERATOR_EQUAL_TO, $userName),
new Predicate\PredicateSet(
[
new Predicate\Like('shipment_number', '20151106052811'),
new Predicate\Like('shipment_number', '20151110053250'),
new Predicate\Like('shipment_number', '20151116054359'),
],
Predicate\Predicate::COMBINED_BY_OR
],
Predicate\Predicate::COMBINED_BY_AND
);
$select->where->addPredicate($predicate);
这是一个动态解决方案：
use Zend\Db\Sql\Where;
public function searchSitesDeliveries($username, Search $search)
{
if (!empty($search->get_shipment_number()))
{
$valeur = $search->get_shipment_number();
if(is_array($valeur))
{
$result = array();
$valeur = array_unique($valeur);
$where = new Where();
$where->equalTo('username', $username);
if (!empty($valeur) {
$where->nest();
$or = false;
foreach ($valeur as $value)
{
if ($or) $where->or;
$where->like('shipment_number', $value)
$or = true;
}
$where->unnest();
}
$select = $this->tableGateway->getSql()->select();
$select->where($where);
$resultSet = $this->tableGateway->selectWith($select);
return $resultSet;
}
// error processing ... when $valeur isn't an array
}
// error processing ... when get_shipment_number is empty
}
我认为@newage的回应很好，但也许你可以像这样使用IN SQL语句
SELECT *
FROM vw_my_asn_header
WHERE username = 'toto'
AND shipment_number IN ('20151106052811', '20151110053250', '20151116054359')
ORDER BY message_id ASC
通过 Zend\Db，您可以使用
new Predicate\In('shipment_number',array('20151106052811', '20151110053250', '20151116054359'))
我正在做这个解决方案，它有效，但我不喜欢我的代码，因为它是静态的，如果有人有使其动态的提示，我很感兴趣。
public function searchSitesDeliveries($username, Search $search)
{
if (!empty($search->get_shipment_number()))
{
$valeur = $search->get_shipment_number();

{
$result = array();
$valeur = array_unique($valeur);
$compteur = 0;
foreach ($valeur as $key => $value)
{
$compteur = $compteur + 1;
$result[$compteur] = $value;
}
$select = $this->tableGateway->getSql()->select();
switch($compteur)
{

$predicate_set = new Predicate\PredicateSet(array(new Predicate\Expression('username = ?', $username)), Predicate\PredicateSet::COMBINED_BY_AND);

$select->where($predicate_set);
