Logging all the sql in Magento for debug

In Magento development you need some time to check the sql query running in the background

For this you can insert a code into the lib/Varian/Db/Adaptor/Pdo/Mysql.php


$code = 'SQL: ' . $sql . "\r\n";
if ($bind) {
       $code .= 'BIND: ' . print_r($bind, true) . "\r\n";
}
$this->_debugWriteToFile("[".date('Y-m-d H:i:s')."] ".$code);


in your query method of the page.
now your query method look like

    public function query($sql, $bind = array())
    {
        $this->_debugTimer();
        try {
            $this->_checkDdlTransaction($sql);
            $this->_prepareQuery($sql, $bind);
         
/* Inserted code Starts */
           $code = 'SQL: ' . $sql . "\r\n";
           if ($bind) {
                $code .= 'BIND: ' . print_r($bind, true) . "\r\n";
          }
          $this->_debugWriteToFile("[".date('Y-m-d H:i:s')."] ".$code);
/* Inserted code Starts */

            $result = parent::query($sql, $bind);
        } catch (Exception $e) {
            $this->_debugStat(self::DEBUG_QUERY, $sql, $bind);
            $this->_debugException($e);
        }
        $this->_debugStat(self::DEBUG_QUERY, $sql, $bind, $result);
        return $result;
    }


You can find the log at /var/debug/pdo_mysql.log


Mage::log("MyArray:".print_r($arr,true), null, 'logfile.log');

create a method in your helper:

<?php
class Rajiv_Catalog_Helper_Data extends Mage_Core_Helper_Abstract {
public function getTopCat(){
$category = Mage::registry('current_category');
$it = 10; //Amount of iterations before script gives up

if ($category) {
while($category->getLevel() != 2 && $it > 0) {
$category = $category->getParentCategory();

if (!$category) {
break;
}
}
