Question

I been trying to understand Magento and I read many things on the wiki, but I couldn’t figure out How does Magento works with database tables? because I didn’t see any SQL

Answer 1

If you watch your MySQl log, the calls made by magento can sometimes be 500 lines long or longer … These calls are dynamically constructed using XML files. The best way to manipulate Magento data manually is to use MAGE:: calls or use a direct database connection by using:

$read = $resource->getConnection('core_read');
$sql = "select * from [YOUR_TABLE] where 1 limit 1";
$result = $read->query($sql);

It’s either that or calls that look like:

$value = 'some value';
$item->setData('some_key', $value);
$item->save();

Magento is object oriented, so those are the most commonly accepted and used ways to retrieve/set data in Magento. I hope that helps.
