I have MSDE on my PC and am considering downloading SQL Express 2008 R2 on the same machine as a new instance so I can have both. Is it possible to open one instance of Toad and and show the databases currently in MSDE and a separate instance of Toad and show SQL Express? If so, how is this done? Will MSDE and SQL Express appear as two different servers or is there some other way they will be distinguished? Are there any known pitfalls to this approach?
