index on large column

[ssinha]

I have a varchar2(1000)
I need to create index on this field
The data in this feild is probably 50 characters long
I understand that varchar2 does not allocate all 1000 characters .
Is there any performance difference if this field was varchar2(60)?
DOes ther performance matter if this field was indexed ?

I think it shouldn't make any performance difference.
