Magento: Set LIMIT on collection

Question

The question that I tried to find out was how do we set a Limit on a Collection, the answers that I found on Google was only available for the Catalog with a setPage($pageNum, $

Answer 1

There are several ways to do this:

$collection = Mage::getModel('...')
            ->getCollection()
            ->setPageSize(20)
            ->setCurPage(1);

Will get first 20 records.

Here is the alternative and maybe more readable way:

$collection = Mage::getModel('...')->getCollection();
$collection->getSelect()->limit(20);

This will call Zend Db limit. You can set offset as second parameter.
