Version : Oracle 8i


I have table a with an in  index on  a  'char' field.  Will there be any
difference in index performace


based on whether a column is char as opposed to varchar2 ?
I know that  the 'comparison semantics'  differ for   char & varchar2  but I
would like to know the


difference between  char & varchar2  from performance stand point.



Thanks
