I have to write a query which extracts everyone from a table who has the same surname and forenames as someone else but different id's.
The query should have a surname column, a forenames column, and two id columns (from the person column of the table).
I need to avoid duplicates i.e. the first table id should only be returned in the first id column and not in the second - which is what i am getting at the mo.
This is what i have done
select first.surname, first.forenames, first.person, second.person
from shared.people first, shared.people second
where first.surname= second.surname
and first.forenames = second.forenames
and not first.person = second.person
order by first.surname, first.forenames
and i get results like this
Porter Sarah Victoria 9518823 9869770
Porter Sarah Victoria 9869770 9518823 - i.e. duplicates
I'm new to SQL and tried to develop a simple query on multiple tables of a database. The query works but returns duplicate records even though there aren't duplicate records in the database.
Here is the script:
SELECT LelyDevice.iAddress, LelyDeviceVisit.tEndVisitDateTime, LelyCow.dBirthDate, LelyCow.iUserNumber, LelyAstronautVisit.lRefusal, LelyAstronautVisit.lFailedMilking, LelyMilkVisitData.nMilkYield, LelyLactationProduction.dCalvingDate FROM LelyDevice INNER JOIN LelyDeviceVisit ON LelyDevice.PK_LelyDevice = LelyDeviceVisit.FK_LelyDevice INNER JOIN LelyCow ON LelyDeviceVisit.FK_LelyCow = LelyCow.PK_LelyCow INNER JOIN LelyAstronautVisit ON LelyDeviceVisit.PK_LelyDeviceVisit = LelyAstronautVisit.FK_LelyDeviceVisit INNER JOIN LelyMilkVisitData ON LelyDeviceVisit.PK_LelyDeviceVisit = LelyMilkVisitData.FK_LelyDeviceVisit INNER JOIN LelyLactationProduction ON LelyCow.PK_LelyCow = LelyLactationProduction.FK_LelyCow
WHERE LelyDeviceVisit.tEndVisitDateTime BETWEEN '2006-07-29 03:20:00.000' AND '2006-08-03 08:58:59.000' AND LelyAstronautVisit.lFailedMilking = 1 ORDER BY LelyDeviceVisit.tEndVisitDateTime DESC
and here is the result: 13012006-08-03 08:57:39.0002002-07-03 00:00:00.000209015.12005-06-02 00:00:00.000 13012006-08-03 08:57:39.0002002-07-03 00:00:00.000209015.12004-06-06 00:00:00.000 13012006-08-02 20:21:54.0002002-07-03 00:00:00.000209012.72005-06-02 00:00:00.000 13012006-08-02 20:21:54.0002002-07-03 00:00:00.000209012.72004-06-06 00:00:00.000 11012006-08-02 19:26:44.0002002-11-20 00:00:00.000221010.02005-03-27 00:00:00.000 13012006-08-02 19:16:33.0002002-11-20 00:00:00.000221012.32005-03-27 00:00:00.000
As you can see the first 2 lines are the same date and time and the next 2 and so on.

I have duplicate results in from my query. I am using the distinct clause but this does not seem to be working. In the example below, I do not want the 79.15 to repeat multiple times eventhough the first column has all distinct values. I am using distinct in my select but this is not stopping the duplicates on the second row. Any guidance would be greatly appreciated. Thanks
I've begun to get the above error from my package. The error message refers to two output columns.
Anyone know how this could happen from within the Visual Studio 2005 UI? I've seen the other posts on this subject, and they all seemed to be creating the packages in code.
Is there any way to see all of the columns in the data flow? Or is there any other way to find out which columns it's referring to? Thanks!
I am trying to get people from my table that have closed accounts. However, in my table many people have more than one account. They will have multiple closed accounts and some active accounts. I need to get the people with only closed accounts.
Values in the table
Code: name surname status Closed Number ----------- --------- ----------- ------------- ---------------------------- Jeff Burns closed 2012/01/01 142 Tina Drewmor closed 2008/05/20 546 Jeff Burns active 1900/01/01 354 Kyle Higgin active 1900/01/01 851 Tina Drewmor closed 2009/04/14 154
The query I am using so far is:
Code: select d.name, d.surname, s.status, s.closed, s.number from d d inner join s s on d.number = s.number where s.status = 'closed'
What I need to see in the results
Code: name surname status Closed Number ----------- --------- ----------- ------------ ----------------------------- Tina Drewmor closed 2008/05/20 546 Tina Drewmor closed 2009/04/14 154
Query should only return less than 3000 records but its returning over 4M. It needs to show all duplicates records.... All the info are on the same table VENDFIl, so I used a self join but it seems to be looping..
SELECT A.FEDTID, B.VENDOR, C.NPI_NUMBER FROM VENDFIL A, VENDFIL B, VENDFIL C GROUP BY A.FEDTID, B.VENDOR
Hi,Say I have a table Job with columns name, date, salary . I want to getthe name ,date and salary for the date when that person earned maximumsalary. I am using something likeSELECT X.name,X.date,X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);The problem is ; if a person earns maximum salary on two dates, both ofthe dates are printed. I just want to get any one of those two rows.I triedSELECT X.name,Min(X.date),X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);but it gives error.Can anybody please suggest a solution?Regards,Aamir
I have three tables, Accounts, AccountCustomer and Customers, and the data-relationshiop between are defined according to the image below:
I created also a query (the sql-query below), displaying the customers for every account that is on the table "Accounts", and I got the results, as we can see in the image below:
SELECT A.AccountID, c.CustomerNo, c.Surname, c.Name, c.TaxNum FROM Accounts A left join AccountCustomer ac on ac.AccountID = A.AccountID left join Customers c on c.CustomerNo = ac.CustomerNo order by A.AccountID;
As we understand, an "AccountID" have multiple customers, so I want to transform tha multiple results to one row, grouping by AccountID (one account belongs to one or many Customers), like the image below:
I tried to use row_number()-expression to get this, but I didn't make it. So my question is, how can I alter my sql-query to get the final result like image above?
Hello, I have a table with say 45 columns. I have a business requirement that requires me to fetch the rows for which col1 , col2, ....col 11 are same and rest can be different. there is an identity column, in the table so I can have duplicate rows also.
how can I effectively write a query that will fetch me all those rows for which my 11 columns are same.
I have a results table that was created from many different sources in SSIS. I have done calculations and created derived columns in it. I am trying to figure out if there is a way to remove duplicate rows from this table without first writing it to a temp sql table and then parsing through it to remove them.
each row has a like key in a column - I would like to remove like rows keeping specific columns in the resulting row based on the data in this key field.
Hello, I have a table T1 and on this table I have an insert trigger. In the trigger I need to check if T1.ID and T1.Type=’xyz’ together are duplicated or not (duplicate dhcek on two columns), if yes return error from trigger. There might be T1.ID and T1.Type=’abc’ duplicated, that is fine.
I have a question regarding duplicate records, the thing is I'm able to query for duplicated records if I type the following:
select ColumnName from TableName where ColumnName in ( select ColumnName from TableName group by ColumnName having count(*) > 1 )
That gives me duplicate records for one column, but I need find duplicate records in more than one column (4 columns to be exact), but the way I need to find these records is they all have to be duplicate, what I'm trying to say is I don't don't want to find the following:
First Last Age Email John Smith 25 jsmith@hotmail.com John Smith 26 jsmith@hotmail.com John Smith 25 jsmith4@hotmail.com
I need to find the following:
First Last Age Email John Smith 25 jsmith@hotmail.com John Smith 25 jsmith@hotmail.com John Smith 25 jsmith@hotmail.com
So all the columns must be exactly the same, that's the only condition I want to show the records, is there any way to do this?
For the record, I'm using MS SQL Server 2000, thank you.
When I add this code in a view and try to save . . .SELECT TOP 610 *FROM dbo.Master INNER JOINdbo.TypeByCase ON dbo.TypeByCase.CaseNum = dbo.Master.CaseNumIt gives the error:ODBC error: [Microsoft][ODBC SQL Server Driver]Column names in eachview or function must be unique.

Hi there,I would like to know how to get rows with duplicate values in certaincolumns. Let's say I have a table called "Songs" with the followingcolumns:artistalbumtitlegenretrackNow I would like to show the duplicate songs to the user. I considersongs that have the same artist and the same title to be the same song.Note: All columns do not have to be the same.How would I accomplish that with SQL in SQL Server?Thanks to everyone reading this. I hope somebody has an answer. I'vealready searched the whole newsgroups, but couldn't find the solution.

f_namef_countryf_ID ABCUS123 DEFGB123 ABCUS456 GHIGB789 etc.
I need to run a query to discover all instances where a f_name and f_country pair exists for more than one f_ID. ABC/US is one such example; IDs 123 and 456 have this pair.
I'm in the process of trying to identify duplicate contacts. I doing this for millions of contacts and have gotten stuck and could use some elegant solutions!
The business rule is this:
Any contact that has the same name, phone and email address are the same contact Any contact that has the same name, and email address are the same contact Any contact that has the same name, email address, but different phone are a different contact. Any contact that has the same name, email address, and a blank phone can be the same contact as one that has the same name, email address, and has an email address Rank by the DataSource_fk. 1 being the highest
Put another way:
If 3 contacts have the same name, 2 have phone '1112223344' and all three have the email address 'johndoe@gmail.com' they are the same contact and the lowest DataSource_fk should be ranked the highest.
I've used the Row_number over (Partition by) in the past, but am unsure how to deal with the blanks in email and phone.
DROP TABLE [dbo].[TestBusinessContact]; GO CREATE TABLE [dbo].[TestBusinessContact] ( [TestBusinessContact_pk] INT IDENTITY(1,1)NOT NULL, [Business_fk]INT NOT NULL CONSTRAINT DF_TestBusinessContact_Business_fk DEFAULT(0),
I have a lot of different data flows that need "Derived Column". There are maybe only 5 different such "Derived Column" but they appear many times. Is there a way to eliminate all that double work? It should be something that does not take me more time to do than just duplicating all the "Derived Columns".
Hi ,I need to place the results of two different queries in the same resulttable parallel to each other.So if the result of the first query is1 122 343 45and the second query is1 342 443 98the results should be displayed as1 12 342 34 443 45 98If a union is done for both the queries , we get the results in rows.How can the above be done.Thanks in advance,vivekian
Hi, I have following data coming from prior transformations.
Id Unit Name NewFlag ___ __________ ____________
1 JacuzziBox 1 2 Hummer H2 0 3 Waste dumper 0
and so on.
I want aggregate task to result 2 fields (without any GROUP BY-ing), so that one contains total number of rows or records, and one contain total number of records with NewFlag=1.
Just wondering if it is possible by using Aggregate and how.
