varchar means fixed length character data(size) ie., min size-1 and max-2000
where as varchar2 means variable length character data ie., min-1 to max-4000
Varchar & Varchar2 both having the same size, & working as same.
Bt the main diff is varchar is an ANSI Datatype & Varchar2 is the Oracle datatype.
Varchar - If we declare datatype as varchar then it will occupy space for null values. It can store upto 2000 bytes of character.
Varchar2 - If we declare datatype as varchar2, it will not occupy any space. It can store 4000 bytes of character.
