    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.
