> The syntax proposed is the following:
> RANK <alias> (BY (<col_ref>|<col_range>)+)?
> Which now is running on the patch attached with the code implemented so far, with the corresponding tests.
> And small update to the syntax:
> RANK <alias> (BY (<col_ref>|<col_range>)+)? DENSE
> I append "DENSE" for dense rank implementation.
> Looking forward to reading your comments.
