Yii调试SQL的常用方法,yii调试sql

Yii调试SQL主要有以下方法:

一、系统自带调试:

首先index.php开启调试模式:

// remove the following lines when in production mode 
defined('YII_DEBUG') or define('YII_DEBUG',true); 
// specify how many levels of call stack should be shown in each log message 
defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3); 
//app use time 
//defined('YII_BEGIN_TIME') or define('YII_BEGIN_TIME',microtime(true));

main.php页面:

'errorHandler'=>array( 
  // use 'site/error' action to display errors 
  'errorAction'=>'site/error', 
), 
'log'=>array( 
  'class'=>'CLogRouter', 
  'routes'=>array( 
    array( 
      'class'=>'CFileLogRoute', 
      'levels'=>'error, warning', 
    ), 
    // 下面显示页面日志 
    array( 
      'class'=>'CWebLogRoute', 
      'levels'=>'trace',   //级别为trace 
      'categories'=>'system.db.*' //只显示关于数据库信息,包括数据库连接,数据库执行语句 
    ),    
  ), 
),

YII_TRACE_LEVEL的数字越大,信息越清楚

二、使用调试工具调试:

yii-debug-toolbar把包解压后 放到extensions里边 然后在配置文件main.php中最后加上

'log'=>array( 
   'class'=>'CLogRouter', 
   'routes'=>array( 
     array( 
       'class'=>'ext.yii-debug-toolbar.YiiDebugToolbarRoute', 
       'ipFilters'=>array('127.0.0.1','192.168.1.215'), 
     ), 
   ), 
 ),

没有出现的话加上在'components'下的db里加上两个属性,

'enableProfiling'=>true, 
'enableParamLogging'=>true,

然后如果有其他调试工具的插件的话,可能会出现冲突导致sql语句不出来,把那段代码注掉即可。

(急)yii SQL查询出的结果数组转换成AR模式

除了cactivedataprovider,你还可以使用CArrayDataProvider
我给你写个例子:
controller中:
$rawdata = Yii::app()->db->createCommand('select * from {{post}} where idqueryAll();

$data = new CArrayDataProvider($rawdata, array(
'id' => 'user',
'sort' => array(
'attributes' => array(
'id', 'title', 'content'
),
),
'pagination' => array(
'pageSize' => 10,
),
));
$this->render('gridview_array', array('dataProvider' => $data));

然后view中:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'somegrid',
'dataProvider'=>$dataProvider,
'columns'=>array(
'id',
'title',
'content',
),
));
这样就ok 了~
 

SQL函数怎调试

就是一个一个实验了, 看看哪个结果返回的是你要的。这种自解释的语言没有什么所谓的调试方法。一条命令就搞定的,你认为怎么算是调试呢
