如何在Magento中将特定属性的字符串数据类型更改为Integer

I created an input field attribute in Magento Catalog->Attributes->Manage Attributes. However, Magento saves all these data as string.

Question:

Is there a way I can change the data type of that specific attribute to integer via admin dashboard?

Or

Do I need to locate the exact database table of that attribute to change it as integer?

UPDATE: As @SimBeez mentioned that there is no way to change the data type of an attribute in admin back end.

UPDATED QUESTION:

How can I programatically update the data type of a specific attribute from string to Integer?

Thanks!

There is no any way to change attribute type INT (admin panel), By default Magento store data as a string.

I would suggest you not to touch DB instead delete your old custom attribute & make new one & while making it(from magento admin) you can select "Input Validation for Store Owner" & can select "Integer Number"
