Body
After looking under the hood I learned that <code>_selectAttributes</code> instance field was not assigned in <code>Mage_Eav_Model_Entity_Collection_Abstract</code> class and that is why get exception. A solution usually would be what Jonathan Day suggested above - add <code>addAttributeToFilter()</code> method, however. It will return error since it cannot find such attribute for catalog/product. (<code>qty</code> and <code>in_invetory</code> are in <code>cataloginventory_stock_item</code>). I found two solutions to my problem both required going different direction: <ol> <li>One involved pursuing a way to query the Select statement that I had set for product collection(see above) but somehow it was not resetting the collection with new product. WhenI copied that Sql statment in phpMyAdmin, it worked, so how to query that statement from product collection: <pre><code> $stmt = $products->getConnection('core_write')->query($products->getSelect()->__toString()); while($rows = $stmt->fetch(PDO::FETCH_ASSOC)){ echo " Product Id ".$rows['entity_id']; } </code></pre></li> <li>Instead of using <code>catalog/product</code> entity table I used the flat table - <code>cataloginventory_stock_item</code> to accomplish the same thing <pre><code>$stockItem = new Mage_CatalogInventory_Model_Stock_Item(); $stockItems->addQtyFilter('>',0); $stockItems->addFieldToFilter('is_in_stock',array('eq'=>'1')); </code></pre></li> </ol> Now there is a collection of all products with <code>qty > 0</code> and that are in stock.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
