从Magento集合输出原始SQL查询

我有以下收藏，并希望在我的IDE Xdebug工具中查看原始SQL-

I have the following collection and want to view the raw SQL within my IDE Xdebug tool -

$collection = Mage::getResourceModel('rp/organisation_collection')
                ->searchByPostcodeLastname($postcode, Slastname)
                ->addFieldToSelect(array('organisation_id'))
                ->setPageSize(1);

$qry = $organisation->load()->getSelect();

这虽然显示Varien对象似乎并没有给我原始SQL供我检查-有人可以确认我做错了吗?

This while does show the Varien object doesn't seem to give me the raw SQL for me to check - can someone confirm what I am doing wrong?
