Yep... did that in November, but had to take my work laptop with me too.  Fortunately I only had to take care of 2 issues the week I was out of state.  I try to document everything and anything database related in our IT department's Wiki, and the day before my last day I always put together a list of routine stuff, known issues and how to handle them, where I store all my "magic" scripts that no-one else seems to understand, and the third party password manager file location.  I still get questions though.

I've put a lot of effort to improving the database ecosystem, and when I started people didn't have a good view of things.  The first 3 months here was difficult as I wrestled the octopus to get things to a manageable level, but once I did it allowed me to focus on being able to help the developers better learn SQL to improve their applications and make things run smoother so that people weren't always upset with performance and problems.
