It's been awhile, but...
     
Today a requirement came up where I have to identify duplicate keys in a 
file.  In the past, I used SQL to do this and seem to recall using count(*) 
in some fashion, i.e.:
     
  select pdiv, ptyp, pvnd, ppo, count(*) from pohedrl3 
  group by pdiv, ptyp, pvnd, ppo
     
This results in:
     
               VENDOR                            
  DIV  TYPE    NUMBER   PO NUMBER     COUNT ( * ) 
  ---  ----  --------  ----------  --------------
   1   MSC    70,225       8,101               1 
   1   MSC   110,275       7,724               1 
   1   MSC   160,415       7,725               1 
   1   MSC   160,415       7,726               1 
   1   MSC   160,415       7,727               1 
   1   MSC   160,415       7,728               1 
(continued for 10000 more rows)
     
How do I specify that I only want count(*) > 1?  Specifying "where count(*) 
> 1" causes numerous syntax errors, no matter where I place it.  A look at 
the infocenter SQL manuals yielded no clues.
     
If someone answers this, could you kindly reply to DBale@TFSA.Textron.com as 
well as MIDRANGE-L so that I get this ASAP?  Thanks!
