当debug设置为0时,如何获得执行查询的列表?

我在AppController中有以下功能:

// log INSERT, UPDATE, DELETE queries
private function __logQueries(){
    $db         = &ConnectionManager::getDataSource('default');
    $query_logs = $db->getLog();

    if( isset($query_logs['log']) && !empty($query_logs['log']) ){

        $this->loadModel('SqlLog');

        foreach($query_logs['log'] as $log_q){
            $query = $log_q['query'];
            if( stristr($query, 'INSERT ') || stristr($query, 'UPDATE ') || stristr($query, 'DELETE ') ){

                $q_data = array(
                        'query'     => $query,
                        'page'      => $this->Misc->getCurrentPageURL(),  // get the current page
                        'referrer'  => trim(env('HTTP_REFERER')) == '' ? '' : env('HTTP_REFERER'),
                        'ip'        => env('REMOTE_ADDR'),
                        'browser'   => env('HTTP_USER_AGENT'),
                        'user_id'   => SessionComponent::check('Auth.User') ? SessionComponent::read('Auth.User.id') : 0,
                        'username'  => SessionComponent::check('Auth.User') ? addslashes(SessionComponent::read('Auth.User.username')) : '',
                    );

                $this->SqlLog->create();
                $this->SqlLog->save($q_data);

            }
        }
    } // end if query occured

}

public function beforeRedirect(){
    $this->__logQueries();
}

public function afterFilter(){
    $this->__logQueries();
}

当debug设置为2时,会记录insert,update和delete查询,但是当debug设置为0时如何记录这些查询?

2 个答案:

答案 0 :(得分:0)

是否记录查询取决于DboSource::$fullDebug属性,它是在DboSource构造函数中设置的,默认情况下truedebug > 1 true }}

所以你要做的就是用debug覆盖这个属性的值,这样就可以确保在这一点上记录查询,无论App::uses('ConnectionManager', 'Model'); ConnectionManager::getDataSource('default')->fullDebug = true; 设置如何。

在指定的路径中创建自己的dbo文件:

更改sql日志文件路径$ filename ='C:\ xampp \ htdocs \ your_project_dir \ app \ sql.txt';

第2步:打开/app/config/database.php 并更改'driver' => 'dbo_mysql_with_log',

这将在以下路径中记录所有sql脚本

C:\xampp\htdocs\your_project_dir\app\sql.txt
