Caching is used to prevent calls to the database. Usually caching systems like Memcached use Memory, that's extremely fast. For instance, if you have a huge trafficked website if for each single request you have to do that select on MySQL you are wasting resources.

What you have to do is to cache the result but then refresh it only after something has changed.

I guess you have a website where you can add new products, after adding a new product you can invalidate the cached version.
