Consider passing named parameters to find and add. That way your existing hash ref gets passed in as a hash with no other change, but a simple find doesn't need to have a hash ref spun up.

Thank you - I don't know why I didn't do it exactly like that because most of the time it will be a hash, not a hashref that gets passed in. Except there are a lot of parameters which could change...hence why I read the table columns out of the information_schema in the new method.
