I often find in my sharepoint development environments that I have issues with transaction logs filling up. This gives me the "Error" page with no indication of what the problem is...yes I can go and change the <customErrors> tag to set the customer errors mode to off and add the callstack to the page but it still doesn't address the problem. I whipped this script up because the dev sql server we are using has well over a hundred db's on it and I didn't fell like manually typing the ALTER DATABASE [xxx] SET RECOVERY SIMPLE for each one or doing the clickity click thing either. Now the solution below probably breaks lots of best practices and such but it works for what I wanted it to do....which is modify all existing db's recovery mode. To modify new db's recovery mode, just set the model db's option to simple and voila..you are ready to go.
Quick note: YOU PROBABLY DO NOT WANT TO EVER...I MEAN EVER...USE THIS ON A PRODUCTION SYSTEM.
