Rajani, find the records with the duplicate names. ;-)
I can't test it, but try something like
select padr(trim(upper(surname))+trim(upper(firstnames)),100) as cName, count(*) as cnt from mytable ;
where internal=1 ;
group by 1 order by 1 ;
having cnt>1
The padr() is to ensure you get the whole name value rather than a truncated version.
Also, consider adding a [ ] between the trimmed names in the index- to preserve the first name/last name distinction.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
