Creating an integer product attribute in Magento is a straightforward process that involves defining the

It seems like the support provided by Varien for those who purchase the Enterprise Edition is not very helpful, so I am turning to this community for guidance.

In Magento, I want to create a product attribute of type int. However, when I try to do this from the admin panel, it ends up being created as a varchar.

My ultimate goal is to establish a "total sold" attribute that can be used for sorting products by the highest number of sales in the category display. The issue with it being stored as a varchar is that when sorted, it treats the values as strings rather than numbers.

Varien informed me that to set this attribute as an integer, I would need to make changes directly to the database. It appears that I would need to update the backend_type column in the eav_attribute table to int, which should then store the values in the catalog_product_entity_int table instead of catalog_product_entity_varchar table. Does this plan sound correct? Has anyone else tackled this task before?

Given my experience thus far, is this level of support from Varien what can be expected? Their assistance hasn't been very useful, especially considering how seemingly simple this task should be (especially since I only asked for guidance, not for them to complete it for me).

Changing the type of an existing attribute is a task I've never attempted before. I typically avoid directly modifying the mysql database structure as it can lead to unexpected outcomes, similar to tweaking a memory location in a running desktop application without full knowledge of its ramifications. Moreover, while I can't provide concrete evidence, it's highly likely that the EAV implementation has evolved over time within the product's lifecycle, resulting in varying solutions for different versions.

If starting anew is an option, consider programmatically adding an attribute to the model (referencing the "Final Array of Key Value Pairs that Define the Attribute" section in this resource). Alternatively, even without starting from scratch, undertaking the creation of an integer attribute programmatically and comparing your database before and after alterations could shed light on the necessary backend adjustments for attribute creation.

Considering changing the backend_type in eav_attribute is a step in the right direction. However, this alone will not transfer the attribute values to

catalog_product_entity_int</code automatically. To achieve this, you must execute an <code>INSERT INTO SELECT

query to move your data from catalog_product_entity_varchar.

If you plan on calculating total sales per product and developing a custom module, you can add a new int type attribute using the mysql-install file following instructions from this blog post. Additionally, utilizing the module creator extension can provide you with the necessary framework to start building your module.

An alternative approach would be to keep the attribute as varchar and modify the category sort to interpret the attribute as an int. Nevertheless, switching the type might be a safer and more efficient solution.

When it comes to expectations for support, the specifics of the agreement will determine whether it covers bug fixes, server and application configuration, and other related tasks. It is unlikely that a support agreement would include writing new code for custom requirements, although there may be exceptions.

Their website clearly states that services such as Code Development, Development Support, and Custom Extensions are not included in their support agreements.

Thank you, Jonathan

I had a similar issue and needed to find a solution without losing attribute values.

To start, I used Magento's dataflow system (System/ImportExport/Profiles) to export products with attributes. Creating a profile to export with 'only mapped fields' selected, I included the SKU and the specific attribute that needed an integer value in the database.

Next, I created a SQL install file within a module to update the database:

$installer->startSetup();
$installer->updateAttribute('catalog_product', '<<your_attribute_code>>', array(
'backend_type'    => 'int',
));
$this->endSetup();
?>

Afterwards, I made sure to reindex product_attribute and product_flat_data.

The following step involved selecting all products using this attribute and updating their values to 100 using the "update attributes" action.

Don't forget to reindex once more!

Lastly, import the file using another profile in the dataflow.

Wishing you the best of luck navigating these steps!
