I have a sql server 2008 db and focussed on two specific columns in a table of over 300 million records. I wanted to find duplicate records which the table has but disinguish from this result set how many and if any of the duplicates have a different field 2.
eg.

field 1: idUrl
field 2: assignedId

so for duplicates of course:

SELECT [idUrl]
       ,[assignedId]
FROM [Feeds].[dbo].[LogFeed]
group by idUrl, assignedId
having COUNT(entryId) > 1
order by entryid desc

So I want to find records where for any duplicates of idUrl are there any records where assignedId is not the same for the duplicate idUrls.

eg

 idUrl            assignedID
 www.google.com       10
 www.google.com       10
 www.google.com       10
 www.google.com        7

    we can write in so many ways i am giving the sample try this one

    DECLARE @table table (idUrl varchar(100),assignedID int)
    INSERT INTO @table
    values(‘www.google.com’, 10),
    (‘www.google.com’, 10),
    (‘www.google.com’ , 10),
    (‘www.google.com’ , 7)

    SELECT idUrl, COUNT ( Distinct AssignedID )   FROM @table 
Group By idUrl Having COUNT( Distinct AssignedID ) > 1
