How i can write query return the douplicate record with deffrint IDs ?! [modified]

[dan sh]

If you will read Shameel's reply to your earlier post, you should be able to figure it out. Anyways, a general query would be:

select [colNames]
from tableName
group by [colNames]
having count(*) > 1

you are right and i know that ! but if i write this :

select [ID,colNames,Phone,...]from tableNamegroup by [colNames]having count(*) > 1

i will have 0 douplicate record !! , why ? because IDs for each douplicted records are different !! and if use all columns without IDs ,i will got douplicted record without IDs. please see the example in my question , i don't need to ignore any IDs. could you please help me to find way? Thanks .

All you need is a variation on SQL code shown by others. Try this:

SELECT ID, otherfields FROM table
GROUP BY otherfields
HAVING COUNT(*) > 1

i.e. don't use MAX(ID) or TOP(ID) and include all fields ("otherfields") that are relevant for identity checking :)

Use CTE feature of SQL server 2005..... Example:

;WITH SalesCTE(Product, SaleDate, SalePrice, Ranking)

AS

(

SELECT

Product, SaleDate, SalePrice,

Ranking = DENSE_RANK() OVER(PARTITION BY Product, SaleDate, SalePrice ORDER BY NEWID() ASC)

FROM SalesHistory

)

DELETE FROM SalesCTE

WHERE Ranking > 1

As Luc mentioned, you don't need to group by ID. You will get the duplicate records then.

Hi, This query works for SQL Server2005,but try to convert for Access2007. A)

CREATE TABLE #tmpData
(
id INT IDENTITY(1,1),
custname VARCHAR(MAX)
)

INSERT INTO #tmpData
SELECT m.Customername
FROM mytable1 m
GROUP BY m.Customername,m.phonenumber,m.city,m.street HAVING COUNT(m.Customername)>1

DECLARE @i AS INT
DECLARE @query AS nvarCHAR(MAX)

SET @i=0
SET @query = 'select * from mytable1 where customername in ('

WHILE(@i<(SELECT COUNT(*) FROM #tmpData))
BEGIN
SET @i=@i+1
SET @query=@query+(SELECT char(39)+custname + char(39) FROM #tmpData WHERE id=@i)+','

END
SET @query=SUBSTRING(@query,1,LEN(@query)-1)
SET @query=@query+')'

EXEC( @query)
DROP TABLE #tmpData

I just played around and found too way to work for Access (I tested it on Access 2003 and not for 2007 version,but i think it should work too for Access2007 version) B)

select a.id,a.Customername , a.phonenumber, a.city, a.street
from mytable1 a
inner join
(select Customername , phonenumber, city, street
from mytable1
group by customername,phonenumber,city,street
having count(*) > 1) b
on a.Customername = b.Customername

Try this Will work for Sql Server(Any version), MySql,Oracle, MSAccess

select * from myTable where customername in (
select customername
from myTable
group by customername,phonenum,city,street
having(count(customername)>1 and count(phonenum)>1 and count(city)>1 and count(street)>1))

Output:

id customername phonenum city street
19 jon 555 NK st.5
37 jon 555 NK st.5

Hope this helps :)
