Zend Framework 2 tablegateway使查询变慢

时间：2014-05-22 06:35:23

标签： mysql zend-framework2

我正在使用zend框架2进行php项目。

我有一个函数，可以运行近300个查询，我使用zf2 tablegateway进行查询。 我的主要问题是完成此操作需要大约120秒。 在使用Byprofiler和Zenddeveloper工具进行分析并提取所有查询之后，我将查询作为独立测试，所有这些查询都需要0.5秒来完成，因此我的结论是tablegateway或zf2增加了119秒的重载。

发生了什么，我该怎样避免这种情况？有关使用zf2的任何建议吗？

修改 以下是查询集：

请注意，由于数据模型的复杂性，这些查询无法以任何方式加入或优化（如果是这样，我会破坏61个加入限制）。

EDIT2 以下是调用retrive值的主要方法：

public function findTreeValues($table, $container_id){

    $ret = array();

    $sql = new Sql($this->tableGateway->adapter);
    $select = new \Zend\Db\Sql\Select;
    $select->columns( array('value') );
    $select->from(array('a'=> $table));
    $select->join(array('b'=>'field_set_value'), new Expression("a.value = b.id "), array('label', 'custom_field_id'));
    $select->where( array('a.container_id' => $container_id) );
    $select->order('b.label');

    $statement = $sql->prepareStatementForSqlObject($select);
    //echo $sql->getSqlStringForSqlObject($select);
    $values = $statement->execute();

    foreach ($values as $v){
        $ret[$v['custom_field_id']][$v['value']] = $v['label'];
    }
    return $ret;
}

public function getValue($custom_field_id, $container_id){

    $obj = $this->find($custom_field_id, $container_id);
    return $obj ? $obj->value : null;
}

答案 0 :(得分：2)

经过调试和调查，我发现ZF2 tablegateway对从db中恢复的数据进行类型解析。对于每个数据，例如对于INT类型的ID或对于字符串类型的字段，它将进行类型转换为正确的php类型。

通常，当你使用mysql从db中选择时，返回数据总是字符串。 这似乎是缓慢的部分：

protected function executeSelect(Select $select)
{
    $selectState = $select->getRawState();
    if ($selectState['table'] != $this->table) {
        throw new Exception\RuntimeException('The table name of the provided select object must match that of the table');
    }

if ($selectState['columns'] == array(Select::SQL_STAR)
    && $this->columns !== array()) {
    $select->columns($this->columns);
}

// apply preSelect features
$this->featureSet->apply('preSelect', array($select));

// prepare and execute
$statement = $this->sql->prepareStatementForSqlObject($select);
$result = $statement->execute();

// build result set
$resultSet = clone $this->resultSetPrototype;
$resultSet->initialize($result);

// apply postSelect features
$this->featureSet->apply('postSelect', array($statement, $result, $resultSet));

return $resultSet;
}

通过简单扩展TableGateway类并删除以下内容来覆盖此方法：

//构建结果集 $ resultSet = clone $ this-＆gt; resultSetPrototype; $ resultSet-＆GT;初始化（$结果）; $ this-＆gt; featureSet-＆gt; apply（＆＃39; postSelect＆＃39;，array（$ statement，$ result，$ resultSet））;

我的应用程序得到了令人难以置信的提升。现在即使复杂的查询也非常快。希望这会对某人有所帮助。
