Answer Posted / dinesh goyal
char is used for fixed length memory storage whereas varchar
is used for variable lenght memory storage.
Fox Example if we have char(10) then we can store 10 bit
value in it but if we store only 6 bit value in it then rest
of the 4 bit space is goes wasted. this limitation is
overcome by varchar.
In varchar if we use less space than define space the rest
of space is not wasted.
