zend-framework - Zend 框架：更新查询

Question

那是我的更新功能：

$id = 5; $points = 100;

public function update($id, $points) {
    $this->update(array('points = ?' => new Zend_DB_Expr('points + 1')), array('id = ?' => $id));
}

但是，当我调用此函数时，会发生错误：

**SQLSTATE[HY093]：参数号无效：没有绑定参数

Answer 1

应该是

$this->update (array (
    'points' => new Zend_DB_Expr ('points + 1') 
), array (
    'id = ?' => $id 
));
