SQL in a Nutshell is pretty good. There shouldn't be any performance benefits if the engine is working properly but it is emminently more readable. You may well hit problems with your SELECT * approach with names colliding, especially when you start adding UNIONs. It is always advisable to use explicit relational variable names (columns).
