What is the difference between CHAR and VARCHAR2? If
VARCHAR2 serves the uses of CHAR why CHAR is still used and
not been discarded yet?
Answer Posted / pradeep
in char it allocates the memory space as static where as in
varchar2 it allocates the memory space as dynamic.
Another difference is accessing a variable declared as char
is faster than, accessing a varchar2. So CHAR is still used
