Show HN: A “Write Less, Do More” DB Class Based on PDO [PHP]

I just want to raise my concern about the security issues the current implementation provides. At a glance the <i>update</i> method provides a simple way to execute arbitrary SQL.<p>Please be aware

TL;DR - it does everything PDO does (thanks to class inheritance) but also has some nice short-hand methods for getting jobs done quicker. DRY and KISS.

Where are the tests?
