AW: Locate duplicate accounts in a file

After having removed the duplicates
... what about adding either a unique key constraint or an unique index to
the file for avoiding future duplicates?

ORDER BY turned out not to be essential. Only five records to deal with.
Definitely nice to know the proper syntax, especially if there had been a
lot more to deal with. Not sure yet, but the duplicates >might< have been
there due to a field that had been forced to a number 1 - a cycle count.
File was prepared elsewhere.

Thanks.

Subject: Locate duplicate accounts in a file

I have a file that is supposed to have one record per account number.
There is at least one duplicate account in the file.

I'm thinking there is a simple(?) way to locate the duplicates with SQL.
But, I am missing something.

I have select siacct, count(siacct) from spbsobdp group by siacct
order by siacct

Which produces a nice list. How can I change the output so only those
records with count > 1 show?

My first thought is to redirect to a file and then query that. Is
there another option?
