Sodium hydrogencarbonate is NaHCO3.
It does not dissolve in water to give a hydrogen atom, but can give a hydrogen ion.
It still has one of the acidic hydrogens of carbonic acid left, so can donate an H+ to a strong enough base:
NaHCO3 + NaOH ----> Na2CO3 + H2O
NaHSO4 is sodium hydrogensulphate. The argument is exactly the same, but I don't know which chemical you are actually referring to.

NaHSO4 is sodium hydrogensulphate. rating: 1 1 0
Addition of more of alkali converts Bicarbonate into Carbonate.
For Example NaHCO3 + NaOH = Na2CO3 + H2O.
Here OH of NaOH is combining with HCO3- to give CO3 -2 and H2O.

You have miss-spell ed the equation. Sodium Hydrogen Carbonate is NaHCO3. It dissociates into Na+ and HCO3 -. HCO3- can behave like carbonic acid, but it will not give Hydrogen atom. Addition of more of alkali will convert Bicarbonate into Carbonate. For Example NaHCO3 + NaOH = Na2CO3 + H2O. Here OH of NaOH is combining with HCO3- to give CO3 -2 and H2O.

Sodium hydrogen carbonate = NaHCO3
Sodium hydrogen sulfate = NaHSO4
They both can be either acidic or basic, depending on the other reactant. That is called amphoteric. Just like water, water can be a Lewis base to form H3O+, but it can also be Lewis acid to form OH-.
HCO3- + H2O <-> H3O+ + CO32-

firstly, the eqn u have given is telling that the substance is sodium bisulphate not sodium bicarbonate.
secondly, sodium bisulphate ionises as follows,
NaHSO4 <==> Na(+) + HSO4(-)
& sodium bicarbonate dissociates as,
NaHCO3 <==> Na(+) + HCO3(-)

forget it. it practically does not. the primary dissociation goes along
NaHSO4 =Na+ + HSO4-
it is true, that the HSO4 ion could dissociate further to
HSO4-= H+ + SO42-
but this equilibrium is almost totally to the left.
