Select Distinct Rows From Duplicate Rows....
Nov 28, 2007
Dear Gurus,
I have table with following entries
Table name = Customer
Name Weight
------------ -----------
Sanjeev 85
Sanjeev 75
Rajeev 80
Rajeev 45
Sandy 35
Sandy 30
Harry 15
Harry 45
I need a output as follow
Name Weight
------------ -----------
Sanjeev 85
Rajeev 80
Sandy 30
Harry 45
OR
Name Weight
------------ -----------
Sanjeev 75
Rajeev 45
Sandy 35
Harry 15
i.e. only distinct Name should display with only one value of Weight.
I tried with 'group by' on Name column but it shows me all rows.
Could anyone help me for above.
Thanking in Advance.
Regards
Sanjeev

Hi, I have the following script segment which is failing:
CREATE TABLE #LatLong (Latitude DECIMAL, Longitude DECIMAL, PRIMARY KEY (Latitude, Longitude))
INSERT INTO #LatLong SELECT DISTINCT Latitude, Longitude FROM RGCcache
When I run it I get the following error: "Violation of PRIMARY KEY constraint 'PK__#LatLong__________7CE3D9D4'. Cannot insert duplicate key in object 'dbo.#LatLong'."
Im not sure how this is failing as when I try creating another table with 2 decimal columns and repeated values, select distinct only returns distinct pairs of values.
The failure may be related to the fact that RGCcache has about 10 million rows, but I can't see why.
Any ideas?

Hello everyone, I'm working on a SQL statement that I "thought" worked fine until I noticed I was getting a duplicate row. Below is the SQL statement from the stored procedure: SELECT DISTINCT number AS 'RteNum', leg_orig AS 'Origin',
leg_dest AS 'Dest', AcEquipment.EquipmentDesc AS 'EquipType',
SUBSTRING(trailer_option, 1, 1) AS 'TrailerOption',
leg_depart_time_local AS 'DeptTime',
leg_arrive_time_local AS 'ArrTime',
dev.fnConvertEffectiveDaysToDaysOfWeek(SUBSTRING(leg_effective_local, 2 ,7)) AS 'EffectiveDays',
TruckEditor.EffectiveDays as 'NewEffectiveDays'
FROM lhif_prod
JOIN AcEquipment ON AcEquipment.EquipmentType = lhif_prod.Equipment_Type
LEFT JOIN dev.TruckEditor ON TruckEditor.Origin = lhif_prod.leg_orig AND TruckEditor.Dest = lhif_prod.leg_dest
AND TruckEditor.RouteNum = lhif_prod.number AND TruckEditor.DeptDate = lhif_prod.leg_depart_date_local
WHERE leg_depart_date_local BETWEEN @DateStart AND @DateEnd
AND Type_Code = 'T' AND leg_orig = @LocID
ORDER BY RteNum, Dest, DeptTime Here is what comes back from this query:ABE00 ABEA ABER CTV5 H 1855 1915 MTWT--- NULLABE01 ABEA ABER CTV5 H 1941 2001 MTWT--- NULLABE02 ABEA ABER CTV5 H 2045 2105 MTWTF-- NULLABE03 ABEA ABER CTV5 H 2059 2119 MTWTF-- NULLABE04 ABEA ABER CTV2.5 H 2245 2305 MTWTF-- NULLABE11 ABEA ABER WALKIN H 2045 2100 MTWTF-- NULLABE11 ABEA ABER WALKIN H 2045 2100 MTWTF-- MT-TF--ABE12 ABEA ABER WALKIN H 2109 2124 MTWTF-- NULLEF038 ABEA EWRHB 53BULK H 0100 0245 -TWTFS- NULLEF085 ABEA EWRHA CTV5 H 1955 2140 MTWT--- NULLEF106 ABEA EWRHB CTV5 H 1901 2046 -----S- NULLEF140 ABEA ABER CTV5 H 0550 0610 M------ NULLEF166 ABEA EWRRA CTV5 H 2230 0010 MTWT--- NULLEF366 ABEA EWRRA CTV5 H 2230 0010 ----F-- NULLEF543 ABEA EWRRA CTV5 H 2200 2345 MTWTF-- NULL The 2 rows in bold are the issue right now. There should only be 1 row (the 2nd one where the last column is not null). I'm not sure why it returns both columns when I'm doing a join on there to add that last column. Can anyone help me out with this? I'm not very strong in SQL, so if I'm overlooking something, I'd appreciate any help you can provide. Thanks.

Hi,
I'm having a little bit of trouble trying to figure out how to do this query, right now I have:
SELECT I.AppItemId, P.ProductID, P.PartNum, P.Relist, I.AppUserId
FROM ProductsToRelist I join Products P on P.ProductID = I.AppSKU
WHERE P.Relist = 1 and I.AppStatus = 5 and Not I.AppItemId is Null
and it returns something like this:
AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
1665 -30987 SELECT_OOS11
2433 -30987 SELECT_OOS11
4272 -30984 SELECT11
2436 -30984 SELECT11
2793 -32708 SELECT11
But I only it want it to return 1 record for each ProductID like so:
AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
4272 -30984 SELECT11
2793 -32708 SELECT11
ProductID is the primary key for the Products table, and a product can be in the ProductsToRelist table many times but each row would have a unique AppItemId. I know that I need to use Distinct or a different kind of join, but I'm not sure which. How would you suggest to do this?
Thanks

I have the following tablecolumns: [col1], [col2],[col3] and [NAME].I want to select the name column for each row where [col1]='07'.The problem is that there are several rows where [col1] contains '07' and also the name is the same. [col2] and [col3] contain different data for these double rows...however, I cant use the [col1] and [col2] values in my query because I dont know what values they contain beforehand.So now, when I execute my query and add the DISTINCT key I still get all the double rows!I hope this explains my problem, help is really appreciated...ow, btw: deleting the double rows is not an option....

I get a tabseparated textfile with data every friday. Faulty rows are to be returned to the source.
Double rows are considered a fault. How do I select all double rows?
I join the data later on with four columns so if these columns are alike the rows are considered identical even if other columns are not. Ie:
A, B, C, D, 12, 34, 48, 76
A, B, C, D, 23, 45, 56, 99
These two rows are considered alike since I join on A+B+C+D.
I'd like to select ALL double rows and insert them into a separate table that I can return to the source. Does anyone have an idea how to do this?

Is it possible to retrieve Distinct rows from this Select Statement?
I'm getting the correct results, but duplicate rows because some customers place more than one order on the same day.
Code:
SELECT dbo.Customers.CustomerID, dbo.Customers.Title, dbo.Customers.FirstName, dbo.Customers.LastName, dbo.Customers.CustomerEmail, dbo.Customers.DateCreated,
CONVERT(char, dbo.Customers.DateCreated, 103) AS [DD/MM/YYYY], dbo.loyalty_points.LPoints, dbo.Orders.OrderID
FROM dbo.Customers INNER JOIN
dbo.loyalty_points ON dbo.Customers.CustomerID = dbo.loyalty_points.CustomerID INNER JOIN
dbo.Orders ON dbo.Customers.CustomerID = dbo.Orders.CustomerID
WHERE (CONVERT(char, dbo.Customers.DateCreated, 103) = CONVERT(char, GETDATE() - 6, 103))

I have a table with four columns: id, value1, value2, and name. I need to select all duplicate rows with the same name in the name field. Once selected I need to average the value1 and value2 rows with each other. Then I would like to delete the duplicate rows and replace with the new averaged values. Should I first move the duplicate rows to a temp table and then average? Any help would be appreciated.

Please help me with an SQL Query that fetches all the records from the three tables but a unique record for each forum and topicid with the maximum lastpostdate. I have to bind the result to a GridView.Please provide separate solutions for SqlServer2000/2005.
I have three tables namely – Forums,Topics and Threads in SQL Server2000 (scripts for table creation and insertion of test data given at the end). Now, I have formulated a query as below :-
SELECT ALL f.forumid,t.topicid,t.name,th.author,th.lastpostdate,(select count(threadid) from threads where topicid=t.topicid) as NoOfThreads
FROM
Forums f FULL JOIN Topics t ON f.forumid=t.forumid
FULL JOIN Threads th ON t.topicid=th.topicid
GROUP BY t.topicid,f.forumid,t.name,th.author,th.lastpostdate
ORDER BY t.topicid ASC,th.lastpostdate DESC
Whose result set is as below:-
forumid
topicid
name
author
lastpostdate

Hi,
I want to select the 8 most saled products from large orders table... the problem is that when i use the "distinct" sentence (something like this- "SELECT TOP 8 distinct id, products, productid FROM tbl_orders ORDER BY id") I get back the distinct of any columns.... (and any ID is distinct, of course), but if i don't include the id's in the distinct sentence, i can't order by id's.
can i get the last orders, only by distinct product, and not by distinct id, and order them by the id's?

I used the following select statement to get duplicate records on Case_number column
select cases.distinct case_link, cases.case_number
from cases
group by case_link
having case_number > 1
I got the error message that
"'cases.warrant_number' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
AND
cases.case_number' is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause.
Any idea on a better statement to use. THANKS FOR YOUR HELP!

Hi. I'm a SQL Server newbie, very experienced with Access, developing an ASP.NET database editor web app. I query the database with a statement more or less in the following form:
SELECT organisation.OrgID, organisation.Name, organisation.whatever FROM services INNER JOIN servicegrouping ON services.serviceID=servicegrouping.serviceID INNER JOIN organisations ON servicegrouping.OrgID = organisations.OrgID WHERE services.service=x OR services.service=y
In other words, I have a database of organisations. The services offered by the organisations are in a separate table, and I only want to return organisations that offer services X or Y.
Okay, now if I did this in Access, this query would return just one record for each organisation that meets the condition, unless I was to include a field from the services table in the SELECT clause, in which case of course I would get one record for each organisation and unique service offered.
But in MS SQL, the query returns duplicate rows if there is more than service offered by the organisation that meets the WHERE condition (=x or =y). Why is this and what do I need to do to my SQL statement to ensure I only get unique rows?

Hi,
I've a query which gets a set of data from multiple tables -
select *
FROM A
inner JOIN q
ON (RIGHT(q.name,CHARINDEX('-',REVERSE(q.name))-1)= a.id)
inner JOIN t
ON (t.id = q.id)
inner JOIN s
ON (q.name = s.name )
inner join l
on (s.name = l.name
and t.name = l.name)
WHERE A.id = 764
and s.name = '764'
I get repeated # of rows for each id. I've some 136 rows for each q.id ( there are 6 q.ids and hence I get 816 rows instead of 136) These 136 rows are actually divided among thse q.ids as
id=5, 4 rows
id=6, 8 rows
id=7, 24 rows
id=8, 40 rows
id=10, 60 rows
total=136 rows
Let me know what I'm missing here
Thanks for your help!

Hi All,
I'm a beginner in SQL and would like some help with writing a query that needs to:
a) Return the latest time that an event happened (along with the event), and also
b) Determine if this event occurred more than 30mins ago.
For example, Table EVENT consists of the following data:
EVENT DateTime,
A 16/1/08, 14:03:55
B 16/1/08, 14:30:27
A 16/1/08, 17:42:18
I would like the results for the first part of query to be:
EVENT DateTime,
A 16/1/08, 17:42:18
B 16/1/08, 14:30:27
I have tried creating a query based off this thread, but for some reason it kept complaining that the EVENT column in Table EVENT didn't exist.
For the part b), I have no clue as to what I should do apart from that I would need to use NOW().
Any help would be appreciated.

Hello,
I have a question, what does a statement look like that finds the duplicate rows and combines them,
I have a table named PRODUCTS in it 3 columbs Cost, Stock, Part_number.
I need to find all Part_numbers that dublicate, Combine the rows into 1 & combine (sum, add) their stock together is the new row & take an avarerage of their cost and use it as cost in the new row where they combine.
Please help me, I am stalled. Looked all over the internet & could not find anything, I really need this for a project I can not finish.
I have the following SQL statement:
SELECT part_number,
COUNT(part_number) AS NumOccurrences
FROM Products
GROUP BY Part_number
HAVING COUNT(part_number) > 1

I have a csv file that I need to import daily into a SQL Server 2005 table. Much of the table contents could just be overwritten with the new csv file, however there are a set of Rows within the table that need to be appended to , rather than overwritten.
There is no Primary Key in the csv file that can be used.
I'm not sure this is the best approach, but what I have been trying to do, is append the entire csv file to the existing table, and then go back and delete the duplicates.
When I run the Delete, it does delete the majority of the records, but leaves a couple hundred behind. The number left behind varies with each run, can't seem to identify a pattern here. Running the Delete a second time does clean up the rows left behind in the first execution of the Delete, and gives the result I want.
Any thoughts as to why this needs to be run twice? Or is a better approach available?
Here is my code -
SELECT [Pkg ID], [Elm (s)], [Type Name (s)], [End Exec Date], [End Exec Time], dupcount=count(*)
INTO temppkgactions
FROM pkgactions
GROUP BY [Pkg ID], [Elm (s)], [Type Name (s)], [End Exec Date], [End Exec Time]HAVING count(*) > 1
DELETE TOP (SELECT COUNT(*) -1 FROM dbo.temppkgactions WHERE dupcount > 1 )
FROM dbo.pkgactions
DROP TABLE temppkgactions
Thanks

I have a large table that consists of the columns zip, state, city, county. The primary key "zip" has duplicates but the rows are unique.
How do I filter out only the duplicate zips.
