Question

I am trying to list all the duplicate records in a table. This table does not have a Primary Key and has been specifically created only for creating a report to list out duplicates. It comprises of both unique and duplicate values.

The query I have so far is:

SELECT [OfficeCD]

      ,[NewID]
      ,[Year]
      ,[Type]
  FROM [Test].[dbo].[Duplicates]

  GROUP BY [OfficeCD]

       ,[NewID]
      ,[Year]
      ,[Type]
      HAVING COUNT(*) > 1

This works right and gives me all the duplicates – that is the number of times it occurs.

But I want to display all the values in my report of all the columns. How can I do that without querying for each record separately?

For example:

Each table has 10 fields and [NewID] is the field which is occuring multiple times.I need to create a report with all the data in all the fields where newID has been duplicated.

Please help.
Thank you.

You need a subquery:

SELECT * FROM yourtable 
WHERE NewID IN (
  SELECT NewID FROM yourtable
  GROUP BY OfficeCD,NewID,Year,Type
  HAVING Count(*)>1
)
