Using expressions in ado/data designer

I was reading on MSDN that one can use calculating expressions in visual studio's dataset designer ([price] * [stock], for example), but what about when it comes to more complicated expressions or functions like datepart() or strings.right() in access? I noticed after research, these functions translate to sql server in almost the same capacity, The VS2010 query builder is not liking any non-operator expression. What do you do if you need pieces of data from a query such as part of a date?

Edit: I have found this listing:

Are these the only expressions supported?
