Re: Locate duplicate accounts in a file

Technically this is a CTE (Common table expression) not a correlated
subquery.

Correlated Subquery.


With List As(
Select SIACCT, Count(SIACCT) as MyCount
From SPBSOBDP
Group By SIACCT)
Select * From List
Where MyCount > 1

I think that is right.

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?
