Transact SQL :: Remove Duplicate Records But Keep At Least 1 Record
Dec 3, 2010I have a table that "Geography" that has the following columns: city, state, zip
There are tons of duplicate cities in this table. I ran this query and it shows me the number of occurrences of each city. I want to delete all the duplicates except for 1. I don't want to do this manually as there are a lot of records.
What would the SQL look like to delete the duplicate records but keep at least one?

Remove Duplicate Entries
May 8, 2008
I am a newb at ms sql and was hoping someone could help me
eliminate duplicate PRODUCT.PRODUCT from this statement. I have tried using DISTINCT with the same results.The ProductImage table is causing this because
the duplicates are from the PRODUCT.PRODUCT that have more than 1 image.
If anyone could rewrite this statement so I can learn from this, it would
be most appreciated!
Thank you for your time
<asp:SqlDataSource ID="SqlDataSource3" runat="server"ConnectionString="<%$ ConnectionStrings:LocalSqlServer %>"SelectCommand="SELECT Product.Product.productid,Product.Product.catid,Product.Product.name,Product.Product.smalltext,Product.Product.longtext,Product.Product.price,Product.ProductSpecial.saleprice, Product.ProductSpecial.feature,Product.ProductImage.imgId, Product.ProductImage.imgUrlFROM Product.ProductINNER JOIN Product.ProductSpecialON Product.ProductSpecial.productid = Product.Product.productidINNER JOIN Product.ProductImageON Product.Product.imgid = Product.ProductImage.imgId"></asp:SqlDataSource>
Remove Duplicate Data
Dec 16, 2004I have a query that for one reason or another produces duplicate information in the result set. I have tried using DISTINCT and GROUP BY to remove the duplicates but because of the nature of the data I cannot get this to work, here is an example fo the data I am working with
ID Name Add1 Add2
1 Matt 16 Nowhere St Glasgow
1 Matt 16 Nowhere St Glasgow, Scotland
2 Jim 23 Blue St G65 TX
3 Bill 45 Red St
3 Bill 45 red St London
The problem is that a user can have one or more addresses!! I would like to be able to remove the duplicates by keeping the first duplicate ID that appears and getting rid of the second one. Any ideas?
Cheers

Sep 5, 2007I have a table containing over 100,000 email addresses. This email table gets duplicates in it, and our customers don't want a second (or third or fourth) copy of our news letter. To prevent this, we run the following SQL to kill the duplicates:
Code Snippet
DELETE FROM _email WHERE _email.eid IN
(
SELECT tbl1.eid FROM _email AS tbl1 WHERE Exists
(
SELECT emailaddress, Count(eid) FROM _email WHERE _email.emailaddress = tbl1.emailaddress GROUP BY _email.emailaddress HAVING Count(_email.eid) > 1
)
)
AND _email.eid NOT IN
(
SELECT Min(eid) FROM _email AS tbl1 WHERE Exists
(
SELECT emailaddress, Count(eid) FROM _email WHERE _email.emailaddress = tbl1.emailaddress GROUP BY _email.emailaddress HAVING Count(_email.eid) > 1
)
GROUP BY emailaddress
);
This query takes about 2hrs to run which is really hurting our server preformance. Is there any way to do this faster?

As you can see, Joe Smith has two rows, but only one of the rows is complete. I would like to delete only the row that has a NULL value in the phone and area code for Joe Smith. There are a few thousand rows that are like this. They have duplicates all but the area code and phone number.I am used to using a CTE to remove duplicates, but I am a little lost on this one. The things that I have tried, have not worked exactly as I planned.

Filtering/Grouping To Remove Duplicate Values...
Oct 18, 2001There's some SQL below (T-SQL) & I'm wanting to have this result set
grouped by Venue_ID in order to remove rows where there are duplicate values contained in just one column.
The columns BCOM_ID contain unique values, but Venue_ID can have duplicate
values. I only want to get rows for one instance of the Venue_ID (per
BCOM_ID) - doesn't matter which instance but basically, no duplicates.
Oh yes, one of the columns is a Bit column.
Any ideas would be welcome & appreciated!
Many thanks,

View 2 Replies View RelatedDuplicate Record Question
May 4, 2004In order to check that a new users ID does not already exist in the database I thought it would be a good idea to put the Insert into a Try Catch statement so that I can test for the duplicate record exception and inform the user accordingly. I was also trying to avoid querying the data base before executing the Insert.
The problem is what to actually test for. When the code throws the exception it is a big long string . .
"Violation of PRIMARY KEY constraint 'PK_Users_2__51'. Cannot insert duplicate key in object 'Users'"
I just thought that there has to be something simplar to test for than comparing the exception to the above string.
Can anyone tell me of a better way of doing this ?
(by the way I am only using Web Matrix and MSDE in case it matters)

Duplicate Record Problem
Nov 4, 2005I am working on a web application that utilizes a sql server database. One of the tables is a large text file that is imported through a DTS package from a Unix server. For whatever reason, the Unix box dumps quite a few duplicate records in the nightly run and these are in turn pulled into the table. I need to get rid of these duplicates, but can't seem to get a workable solution. the query that is needed to get the records is:SELECT tblAppointments.PatientID, tblPTDEMO2.MRNumber, tblAppointments.PatientFirstName, tblAppointments.PatientLastName, tblAppointments.PatientDOB, tblAppointments.PatientSex, tblAppointments.NewPatient, tblAppointments.HomePhone, tblAppointments.WorkPhone, tblAppointments.Insurance1, tblPTDEMO2.Ins1CertNmbr, tblAppointments.Insurance2, tblPTDEMO2.Ins2CertNmbr, tblAppointments.Insurance3, tblPTDEMO2.Ins3CertNmbr, tblAppointments.ApptDate, tblAppointments.ApptTimeFROM tblAppointments CROSS JOIN tblPTDEMO2WHERE (tblAppointments.PatientID = tblPTDEMO2.MRNumber)AND tblAppointments.Insurance1 = 'MED'AND tblAppointments.ApptTypeID <> 'MTG'AND tblAppointments.ApptTypeID <> 'PNV'AND DateDiff("dd", ApptDate, GetDate()) = 0Order By tblAppointments.ApptDateMy first thought was to try to get a Select DISTINCT to work, but couldn't figure out how to do this with the query. My next thought was to try to set up constraints on the table, but, since there are duplicates, the DTS package fails. I assume there is a way to set up the transformations in a way to get this to work, but I'm not enough of an expert with SQL Server to figure this out on my own. I guess the other way to do this is to write some small script or application to do this, but I suspect there must be an easier way for those who know what they are doing. Any help on this topic would be greatly appreciated. Thanks.

Apr 23, 2008So I'm working on updating and normalizing an old database, and I have some duplicate records that I can't seem to get rid of. Every column is identical, right down to what is supposed to be the key. I can't right a delete query to just isolate one row, and I can't delete (or even udpate) any row in management studio. Any thoughts on how to remove the extra rows?
There is a field that's supposed to be unique, so I can write a simple query to get all of the problem rows. The only thing is that they come back in pairs.
