I have student table where duplicate student exist by name with there fathers name and mothers name. I need to search those duplicate records. I do not need ti count them but If there is 5 same student with name then the query will show 5 name then I will delete individually. Below I am trying to show the scenario.
Student_name  Â

I have been given a task to locate duplicate and report duplicate records and am trying to determine the best way to do this with databases that have 1 million records plus.
Say I have a table with 20 columns, I need to check to see if 3 of 10 specific columns match.
So if 2 columns are the same its no problem however if 3 or more match, they are considered duplicate.
I 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?
My query wants to insert new supplier if there is any. And it should ignore, if the supplier is already present in the table. But it is trying to insert the supplier which is already available. For example, I have PART A with 2 suppliers ABC and DEF. I am getting data from third party for PART A with supplier DEF. As per the condition, it should ignore the record because DEF is already available . But my query is trying to insert supplier DEF and following that, I am getting primary constraint error.
-- Inserting new preferred supplier into R5CATALOGUE
DECLARE @DATEPROCESS DATETIME; SET @DATEPROCESS = CAST(DATEADD(D, -((DATEPART(WEEKDAY, GETDATE()) + 1 + @@DATEFIRST) % 7), GETDATE()) AS DATE) INSERT INTO R5CATALOGUE(CAT_PART, CAT_SUPPLIER,CAT_GROSS,CAT_LEADTIME,CAT_PURUOM,CAT_REF,CAT_MULTIPLY,CAT_CURR,CAT_SUPPLIER_ORG, CAT_PART_ORG,CAT_DESC,CAT_MINORDQTY)
Hi , i am using sql server 2005. i have one table where i need to find records that have same citycode and hospitalcode and doctorcode then delete the record keeping only one record of them my problem is table structure have idendtity column which is unique. that is m table structure is something like
Someone ran an update statement multiple times so their are multiple entries in the table. Â What is the quickest way to track down the multiple entries? Â I would only want to see where timein and timeoff exist in the table multiple times for the same id. Â So this would be a duplicate
EntryID -- ID Â -- timein -- timeoff 1487 Â 11 Â Â 2015-05-05 16:33:23 Â 2015-05-05 18:45:26 1623 Â 11 Â Â 2015-05-05 16:33:23 Â 2015-05-05 18:45:26
Now i am trying to insert a duplicate copy test by passing testId..Here is my sp
if not EXISTS(SELECT testName from tblTest WHERE UPPER(@testName) = UPPER(@testName)) BEGIN INSERT INTO tblTest SELECT @userId, testName,duration,totalQuestion,termsCondition,0,GETUTCDATE(),GETUTCDATE() from tblTest WHERE id=@testId SET @insertedTestId=@@identity INSERT INTO tblTestQuestion SELECT @insertedTestId,question,0,GETUTCDATE(),GETUTCDATE() from tblTestQuestion WHERE testId=@testId END
how to insert in answer table as one question can be multiple answers.
I need write a query for removing duplicates, for Example in my table I have columns
A_ID name id 1 sam 10 2 sam 10 3 sam 10 4 sam 10 5 ccc 15 6 ccc 15 7 ccc 15 8 fff 20 9 fff 20 10 fff 20
So now I have duplicates values in id column so now I need to take only one value of each and delete the remaining. I need to take first id value 10,15,20 so only 3 rows should be there in my table.
I have a temp table with the following columns and dataÂ
drop table #temp create table #temp (id int,DLR_ID int,KPI_ID int,Brnd_ID int) insert into #temp values (1,2343,34,2) insert into #temp values (2,2343,34,2) insert into #temp values (3,2343,34,2)
[Code]....
I use the rank function on that table and get the following results
select rank() over (order by DLR_ID,KPI_ID,BRND_ID Â ) Rown,* from #temp
I am interested only in Rown and Id columns. For each Rown number, I need to get the min(ID) in the second column and the duplicate ID should be in 3rd column as shown below.If i have 3 duplicate IDs , I should have 3 rows with 2nd column being the min(id) and 3rd column having one of the duplicate ids in ascending order(as shown in Rown=6)
FileType        Val FILENAMETYPE    Direct
Now my requirement is to search for FIleTYPE in above table by passing  @Filename  as parameter and that should return Val as response. How to write a search query for this type.
I have a table in different databases with the same name. My goal is to compare the two tables, and insert a record into the second table where there is not a match in the first table.  So far, my query looks like the following:
SELECT [metal] FROM [ProductionDatabase].[dbo].[Metalurgy] EXCEPT SELECT [metal] FROM [TestDatabase].[dbo].[Metalurgy]
This gives me a list of records from [Production].[dbo].[Metalurgy] which do not reside in [TestDatabase].[dbo].[Metalurgy]. Now, I need to use that list to insert missing records into [TestDatabase].[dbo].[Metalurgy]. How can I modify the above code to INSERT the missing records?
I have a client who needs to copy an existing sale. The problem isthe Sale is made up of three tables: Sale, SaleEquipment, SaleParts.Each sale can have multiple pieces of equipment with correspondingparts, or parts without equipment. My problem in copying is when I goto copy the parts, how do I get the NEW sale equipment ids updatedcorrectly on their corresponding parts?I can provide more information if necessary.Thank you!!Maria
I have a table of raw data where each column can be null. The thought was to create an identity key (1,1) and set as primary for each row. (name/ address / zip/country/joindate/spending) with surrogate key: "pkid".However other queries will not use this primary key. So for instance they may count the # of folks at a zip, select all names, addresses etc. The queries may order by join date, or select all the people that joined on a specific date.No other code would logically use the primary key (surrogate primary id key), therefore would it still have any performance benefits? at this time the table would have no clustured or nonclustured indexes or keys. I'm curious if there are millions of records.
I'm trying to pull all records from one table and just a single record from another. I have this join, (see below). It works ok, but the problem is if a blog record doesn't have a corresponding image record it doesn't return. The end result should be the blog record and a single corresponding image record. But always a blog record.
Consider a 4 tables where 1 of them is considered to be as the parent class and the other 3 are sub-classes and they are disjoint so for every recored i insert in the parent class i want to also insert in one of the subclass according to a condition which checks a certain attribute in the recored that is also entered in the parent class .. how could this be done .
I just wanted to delete a record from a filetable by "delete from dbo.DocumentStore where stream_id = 'A322276D-AE65-E511-8266-005056C00008'".
Then i received error 1934:
Meldung 1934, Ebene 16, Status 1, Zeile 578 Fehler bei DELETE, da die folgenden SET-Optionen falsche Einstellungen aufweisen: 'ANSI_PADDING'. Überprüfen Sie, ob die SET-Optionen für die Verwendung mit indizierte Sichten und/oder Indizes für berechnete Spalten und/oder gefilterte Indizes und/oder Abfragebenachrichtigungen und/oder XML-Datentypmethoden und/oder Vorgänge für räumliche Indizes richtig sind.
Something that i made a mistake with the SET-option for 'ANSI_PADDING' with indexted views and/or calculated rows and/or filtered indeces ...
Just like Unique/Distinct command, is these some way I could list just the duplicate records from a table . The field is numeric. Thanks a lot for you help.
I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.
When I try to create the tables, for the query, I am getting the following error:
Msg 2714, Level 16, State 4, Line 12
There is already an object named 'UserID' in the database.
Msg 1750, Level 16, State 0, Line 12
Could not create constraint. See previous errors.
I have duplicated this error with the following script:
USE [testing]
IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users1]
CREATE TABLE [testing].[dbo].[users1] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users2]
CREATE TABLE [testing].[dbo].[users2] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users3]
CREATE TABLE [testing].[dbo].[users3] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.
I think that the schema is only allowing a single UserID primary key.
Hi I have created a simple application base on the video based on the 'SQL Server 2005 Express for Beginners' video No. 8.It is working great but I would like to add another feature; if an emial address (in my case userName) is entered that already exists in the database I would like to display an message say you have already subscrided.How do I search the database for a duplicate email address? Please keep it simple I am still finding my feet with aspx and c#.Cheers protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e) { SqlDataSource profilesDataSource = new SqlDataSource();
if (rowsAffected != 1) { // Report a problem Server.Transfer("submit_problem.htm"); } else { // Everything was OK Server.Transfer("submit_success.aspx"); } }
I need to identify duplicate records in a table. TableA [ id, firstname, surname] I’d like to see records that may be duplicates, meaning both firstname and surname are the same and would like to know how many times they appear in the table
I’m not sure how to write this query, can someone help? Thanks in advance!
This is part of my trigger on table T1. I am trying to check if the records inserted to T1 is available in myDB.dbo.myTable or not (destination table). If it is available rollback T1. It does not do that although I insert the same records twice.
-- duplicate record check SET @step = 'Duplicate record' IF EXISTS ( SELECT i.myID, i.Type FROM INSERTED i INNER JOIN myDB.dbo.myTable c ON i.myID = c.myID GROUP BY i.myID, i.Type HAVING (COUNT(*) > 1) AND (i.Type = 'In') ) BEGIN ROLLBACK transaction RAISERROR('Error: step: %s. rollback is done.', 16, 1, @step) Return END

In 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)
I 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.
So 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.

I want to Update one of the duplicate row as I don't have any unique id column. So can anybody update one of the the duplicate record without using any id or altering any column.
