Answer Posted / m arunachalam
These is a simple difference only...
Varchar- It can fixed size to the memory.
Ex:varchar(50)->Memory can take 50 characters to
allocate...
If You given string 'arunachalam' it contains 11 characters
and assign to memory. Remaining 39 character also assign to
empty character in memory....
Varchar2-It can fixed size by your given data length..
Ex:Varchar2(50)->Memory can take 50 characters to allocate...
If You given string 'arunachalam' it contains 11 characters
and assign to memory. Remaining 39 character here not assign
to memory and memory size should be reduced from remaining
size....
