Oracle SQL Syntax for Aggregate Cp

Posted on 2011-09-27

select distinct dictatorid,dictatorlastname, count(dictatorid) 
from ichart.transactions where
reportperiod = '201108'
group by dictatorid, dictatorlastname
order by dictatorid ASC;

Open in new window


Can someone tell me how to modify this Oracle query so it only returns records where the total of each distinct dictatorid is greater than 1?   I am trying to identify dictatorid's that have been assigned to more than one last name and what last names they are assigned to.

Thanks!

SELECT   dictatorid, dictatorlastname
    FROM (SELECT dictatorid, dictatorlastname, COUNT(*) OVER (PARTITION BY dictatorid) cnt
            FROM ichart.transactions
           WHERE reportperiod = '201108')
   WHERE cnt > 1
ORDER BY dictatorid ASC;

Something like:

select dictatorid,dictatorlastname, count(dictatorid)
from ichart.transactions where
   reportperiod = '201108'
group by dictatorid, dictatorlastname
having count(dictatorid) > 1
order by dictatorid ASC;

None of these answers is quite doing it for me.

The way I see it, if any dictatorid shows up at all it should show up at least twice,
ex:  1800NOC     SMITH        2
       1800NOC     JONES       2

But with the examples so far I am getting dictatorids that show up only once with only one of the last names that are assigned to it.

Please try again!

Thanks!

I made the assumption that a given dictator/name combo was unique.

my original query should have picked up what you have shown
but could have also given false-postives on

1, codefinger
1, codefinger

as that is a count of 2 for that id,

this will handle duplicate names on a single id  and will ignore the above


SELECT   dictatorid, dictatorlastname
    FROM (SELECT dictatorid,
                 dictatorlastname,
                 COUNT(DISTINCT dictatorlastname) OVER (PARTITION BY dictatorid) cnt
            FROM transactions
           WHERE reportperiod = '201108')
   WHERE cnt > 1
ORDER BY dictatorid ASC;

sdstuber,

That seems to work pretty well when I add DISTINCT to the first line.  I can probably get away with that, but it would be really cool if I could also have a column that counted the distinct instances so I could sort by it.....so the most over-used dictatorid's could be at the top....

Care to give it a try?
