I’ve written about my DBA Database quite a few times. Some of the code in that database is written recently, and some of it was originally written a decade ago. Regardless of how old it is, or how good of a DBA I was when I wrote it, these little scripts are life-savers, and they are always at my fingertips.
And Andy has made them available to your fingertips as well. And the rest of your hands, I suppose.
