While debugging SQL queries with:

< ?php echo $this->element('sql_dump'); ?>

(in your layout) or DebugKit works great, you have to `render` for it to work. In this particular case that was a problem because I had an `exit;` statement in the middle of my controller to prevent redirection.

The following statement was my rescue:

$log = $this->Model->getDataSource()->getLog(false, false);
debug($log);

I leaves you a nice SQL log in array format!

PS: make sure to replace Model with an actual model name…

    Hi..
    I need your help friend. I want to execute custom sql query in my cakephp app. What should I do with my view file (.ctp)? Example, in my controller :

    function getCount() {

    $qr = “some_queries”;
    $this->set(‘report’, $this->my_model->query($qr));

    }

    Please give me solution for this problem.
    Thank you.

    I don’t now for sure if I understand what you mean, but if you set `report` in your controller (by using custom sql or find) you can use it as `$report` in your view.

    I span the wheel a little bit further and made a switch to output/die or log/continue:

    wont work in production mode.

  6. Charles Santos

    to work in produce mode you need to change the Configure::write(‘debug’, 0); to Configure::write(‘debug’, 2); in config/core.php

  7. tersmitten

    Thats true but you probably don’t want to log SQL queries in production mode. Also Configure::write(‘debug’, 2) is bad for performance since caches are invalidated immediately.

    I am getting

    Error: Call to a member function getDataSource() on null

  14. Mischa ter Smitten

    That means that you’re calling it on a non-existing model (e.g. change Model to User)
