ZF2低于/高于查询不到

Question

SQL查询大

Select * FROM table_name 
WHERE category = 'category_name' 
AND created < 'todays_date' 
AND created > 'yesterdays_date' 

还需要添加ORDER和LIMIT条件。 如何在ZF2中实现这一点？

我有这样的代码：

$rowset = $this->tableGateway->select(function ($select) { 
     $select->where(['category' => $this->category]); 
     $select->order('id Desc'); 
     $select->limit($this->limit); 

     $DBtimeNow = new \DateTime(); 
     $select->lessThanOrEqualTo("created", $DBtimeNow->format('Y-m-d H:i:s')); 
     $DBtimeNow->sub(new DateInterval('P1D')); 
     $select->greaterThanOrEqualTo("created", $DBtimeNow->format('Y-m-d H:i:s')); 
    });

你需要为你想使用运营商使用谓词对象：在这种情况下<=和>=。您可以通过使用ZF2的Zend\Db这个组件Zend\Db\Sql\Where来获得这些信息，因为它扩展了Zend\Db\Sql\Predicate。然后我们可以在需要时使用这些操作员。请查看以下内容：

$select = $this->tableGateway->getSql()->select(); 

// here is the catch 
$predicate = new \Zend\Db\Sql\Where(); 

$select->where(['category' => $this->category]); 

// now use thus 
$DBtimeNow = new \DateTime(); 
$select->where($predicate->lessThanOrEqualTo("created", $DBtimeNow->format('Y-m-d H:i:s')), 'AND'); 
$DBtimeNow->sub(new DateInterval('P1D')); 
$select->where($predicate->greaterThanOrEqualTo("created", $DBtimeNow->format('Y-m-d H:i:s')), 'AND'); 

$select->order('id Desc'); 
$select->limit($this->limit); 

$resultSet = $this->tableGateway->selectWith($select);
