Not really and it's something I've seen a few times...

When someone has a background in VB or C and has been dumped into SQL development then they might be able to write code but they lack the set based thinking which a good DB developer needs (they might not even be aware of being able to return sets depending on how much exposure they're had to databases in their previous life).

Usually a helping hand with their first few pieces of work will get them thinking the right way from the outset.

I know from experience when dabbling in ASP .NET that something which I've spent hours and several tens of lines of code trying to get to work can be ripped apart and rewritten as a very simple class by someone who knows what they're doing
