RE: SQL - selecting issue

["Smith, Mike" <Mike_Smith@xxxxxxxxxxxxxxxx>]

2 things  
"With dups as".(I've never seen this before)   When I include this it
chokes running in STRSQL.  If I run 
(select meter, count(distinct premise)
              from file
              group by meter
              having count(distinct premise) > 1 )

I get the list of meters attached to multiple premises. 

I also need to include the premise. So that if meter 99999 is attached
to 3 premises, I want to know what those 3 premises were along with the
meter#

Corrected (and tested ;-)

With dups as (select meter, count(distinct premise)
              from file
              group by meter
              having count(distinct premise) > 1
             )
Select distinct premise, meter
> From file
Where meter in (select meter from dups)
