  We investigate the implications of the SNO charged-current (CC) and electron
scattering (ES) measurements of solar \br neutrino fluxes for neutrino mass and
mixing parameters by performing a global and unified $\chi^2$ analysis of the
solar neutrino data in the framework of two neutrino mixing. We consider both
$\nu_e -\nu_{active}$ and $\nu_e -\nu_{sterile}$ solutions and perform (i)
analysis of the total rates data of Cl, Ga, SK and SNO experiments and (ii)
global analysis including the total rates data, the recoil electron spectrum
data of SK and the CC spectrum observed at SNO. For the $\nu_e-\nu_{active}$
case the inclusion of the SNO results in the analysis of the total rates
reduces(enhances) the goodness-of-fit (GOF) of the SMA(LMA) solution. The flat
spectrum observed at SK further favours the LMA solution over the SMA solution
and no allowed area is obtained in the SMA region at 3$\sigma$ level from the
global analysis. For the $\nu_e -\nu_{sterile}$ case, with the inclusion of the
SNO results, all the solutions are disfavoured with a probability of more than
99% from the total rates analysis while for the global analysis the GOF of
these become much worse.
