Is it possible to lower case a database field?

Hi There!
I’ve been successfully querying my DB and converting my inputs/queries into lowercase. My challenge right now is that sometimes my database column is mixed case and I’d like case insensitive searches.

Right now I’m doing something like Name = Input:lowercase but is there something like - Name:lowercase = Input:lowercase

Or is a totally easier way for me to do what I want to do? Unfortunately, I do not have control of my data source so right now I cannot change my database content.
