The error you're getting is because the rollno on the order by is not qualified. Just add "s." before rollno and everything should be ok.
Here is an odd one...I changed my compatibility mode to 2k and I got that error. Looking at the code it should throw that in 2008 also because the column truly is ambiguous. In 2k mode it fails but it can be qualified with either g or s and it works (as expected). In 2008 it apparently doesn't care that it is ambiguous. :w00t:
